PET/MR Scanner Development Project on Course
Combining PET and MRI scanning into one machine has great potential for comprehensive imaging of the body. Modern gamma ray detectors use vacuum photomultiplier tubes which are sensitive to magnetic fields, so a major goal of the project was to overcome this limitation. Philips, the leader of HYPERImage, the multi-institution European project to create a PET/MR machine, is announcing considerate success toward its goal.
The milestone that the HYPERImage team has reached is the development of a functional gamma-ray detector that meets the performance requirements of the latest time-of-flight PET scanners. The new gamma-ray detectors have been designed to be compatible with the strong static and dynamic magnetic fields that would be present in a combined PET/MR scanner. Furthermore, the team has achieved major progress with respect to MRI-based static and dynamic PET attenuation correction. Details of these results are presented at the IEEE Nuclear Science Symposium and Medical Imaging Conference, which takes place on October 25-31 in Orlando, Florida, USA.
More about the project from the backgrounder:
The technical breakthrough behind the team's development of an MR-compatible gamma-ray detector is the development of a new solid-state, scalable and compact digital detector technology. This technology is based around silicon photomultiplier arrays that offer the desired sensitivity, energy resolution and timing resolution required for time-of-flight PET measurements, and that feature integrated digital read-out electronics.To increase the effective sensitivity, and to reduce the scan-time and dependence of sensitivity on patient size, the detector has been designed to support time-of-flight PET measurements with extremely short coincidence time resolution. In time-of-flight PET scanners, not only the direction of the gamma ray paths is measured but also the difference in time it takes the pair of gamma rays generated by the PET tracers to reach the detector. This time difference measurement substantially increase the precision with which the tracer can be localized. Time-of-flight measurements increase the effective sensitivity by a factor 10 compared to standard systems.
The silicon photomultiplier array's integrated digital read-out electronics contain a low-jitter and low-power signal acquisition unit. Low power consumption is an essential requirement when preparing the technology for integrated whole body scanning applications.

TRUMF's OR Table Integrated With Siemens Multi-axis Fluoroscopy Systems
Siemens has just announced that it has integrated the TruSystem 7500 OR table from TRUMPF (Puchheim, Germany) with its Artis zee and Artis zeego fluoroscopy scanners. The TruSystem 7500 adjusts to just about any position imaginable and is transparent to x-rays, and so can be used in almost any surgical or invasive radiological procedure. TruSystem 7500 OR table is illustrated above, and Artis zeego multi-axis interventional fluoroscope is shown in the picture below.
The Trumpf OR table has been designed especially for this integration and is equipped with a onepiece carbon tabletop, which can be replaced by a segmented universal tabletop. The table column enables the two tops to be exchanged easily. The carbon tabletop is transparent to X-rays and thus ensures that there will be no disruptive artifacts in the images. It is suitable for interventional procedures and minimally invasive surgery. The integration of the OR table with the Siemens angiography systems also make fast rotations and 3-D imaging possible with the surgical C-arm. The modular design of the segmented tabletop enables extremely flexible positioning of the patient, particularly important in orthopedics and neuro surgery. Complicated positions, such as the chest side position, can be achieved quickly with great precision as well as comfort for the patient and staff.
Along with the integrated Trumpf OR table, Siemens continues to offer its Artis tables for the entire Artis zee series, which are available in three designs: as a standard table, a table with Trendelenburg tilting and one with Trendelenburg and lateral tilting.

GE's New Ultra Small Ultrasound May Become as Ubiquitous as Stethoscope
Yesterday at the Web 2.0 Summit in San Francisco, GE showed off their new 
handheld ultrasound device. The Vscan looks like a cross between an iPod and a cell phone, making it possibly the world's smallest ultrasound. Later today we'll be attending GE's healthymagination technology showcase in New York where further details and specs will hopefully become available.
For critical care clinicians, Vscan can offer an immediate look beyond patient vital signs with the potential to identify critical issues, like fluid around the heart, which could be a sign of congestive heart failure. And for cardiologists, Vscan provides a dependable visual evaluation of how well the heart is pumping at a glance, so they can treat patients more efficiently.

Siemens Adds Tomosynthesis to Its Top Line Mammography System
The Mammomat Inspiration mammography system from Siemens now features the company's 3D tomosynthesis imaging that delivers high quality volumetric views of the breast. With the help of this digital reconstruction technology, clinicians should now avoid false positives by evaluating a suspected tumor from different angles.
So far, conventional analog mammography and digital full-field mammography was only able to display the three-dimensional anatomical structure of the breast on a two-dimensional level. This made diagnosis more difficult and limited the possibility of the physician identifying certain types of tumor; since, anatomical structures could overlap and obscure lesions. The 3D tomosynthesis technology in the Mammomat Inspiration overcomes these limitations: The technology acquires several projections of the breast from different angles using a fast detector based on amorphous Selenium (aSe) and uses this raw data to generate a 3D volume set. This enables a better analysis of the type and size of lesions as well as microcalcifications compared to conventional methods. Tomosynthesis increases the sensitivity and specificity of mammography, as well as improving tumor differentiation and classification.Tomosynthesis differs from conventional mammography in the same way that, for example, a CT scan differs from a classical X-ray image. During the examination, the X-ray tube moves in a 50-degree arc around the breast, taking 25 low-dose images. The images are then used as raw data to construct high-resolution 3D images. High spatial resolution and a wide acquisition angle result in the production of mammography images with unparalleled image quality.

Barco's Latest Mammography Monitor
Barco (Kortrijk, Belgium) has released a new version of its Coronis 5MP monitor for mammography applications. The unit features a 12-bit DICOM look-up table allowing for 4096 levels of gray.
The display's diagnostic precision is further enhanced by the next generation Per Pixel Uniformity (PPU) technology. PPU measures and adjusts the luminance output of each of the five million individual pixels on screen, thus eliminating distracting screen noise and improving the display's image uniformity from center to corner.Furthermore, the upgraded system now incorporates a special version of the MediCal QAWeb service, which includes a dedicated mammography quality check. Together with the integrated I-Guard front screen sensor, MediCal QAWeb continuously monitors the display's quality for mammography screening. The intelligent I-Guard sensor also performs automated and intervention-free DICOM calibration and softcopy QA, helping to meet stringent mammography quality standards.
The product's extremely high luminance, high contrast ratio, and dark black levels guarantee exceptional image accuracy. Moreover, facilities will continue to benefit from Barco's DuraLight long-life backlight technology which assures that the Coronis 5MP Mammo will last three times as long as other displays, reducing the total cost of ownership substantially.
To allow for optimum workflow efficiency, the upgraded Coronis 5MP Mammo is bundled with a high-speed Barco display controller. This powerful board lets radiologists load current and prior studies instantly, enabling them to progress smoothly through their diagnostic workflow without having to wait for images.

Philips' New Digital Photomultipliers May Replace Large, Imprecise, Power Hungry Tubes
Scientists at Philips have developed a new fully digital silicon photomultipliers (SiMP's) that may replace detectors within PET scanners as well as open up possibilities for other ultra-sensitive detectors for DNA sequencing and protein/DNA microarrays.
By integrating low-power CMOS electronics into the silicon photomultiplier chip, the team at Philips has developed a digital silicon photomultiplier in which each photon detection is converted directly into an ultra high speed digital pulse that can be directly counted by on-chip counter circuitry. In contrast to conventional silicon photomultipliers, the Philips digital silicon photomultiplier is therefore an all-digital (digital-in/digital-out) device. As a result, it produces faster and more accurate photon counts with extremely well defined timing of the first photon detection, both of which are important factors in applications such as medical imaging scanners and high-energy nuclear particle detectors.The PET system detects pairs of gamma rays (high energy electromagnetic radiation) originating from a radioactive tracer, a small amount of which is injected into the patient prior to the scan. To image metabolic activity, PET typically uses a radioactive derivative of glucose called fluorodeoxyglucose (FDG). This compound mimics the behavior of glucose in the body and can be detected by the PET system.
For so-called ‘time-of-flight’ PET scanners, accurately determining the time at which the first photon arrives at the detector is extremely important. Philips’ digital silicon photomultiplier prototypes achieve a timing accuracy for the detection of the first photon of around 190 ps (full-width, half-maximum using a standard scintillator crystal (LYSO) at 511 keV for two detectors in coincidence).
Conventional silicon photomultipliers (SiPMs) consist of a two-dimensional array of avalanche photodiodes (APDs) each of which is connected in series with its own polysilicon ‘quenching’ resistor. All of these diode/resistor ‘microcells’ are then connected in parallel and the entire microcell array is reverse-biased to a voltage above the diodes’ normal breakdown voltage – typically in the range 30V to 70V. Operating in this so-called ‘Geiger mode’, the diodes are ultra-sensitive to single electron-hole pairs that result in individual diodes experiencing avalanche breakdown. These electron-hole pairs can be generated either by the absorption of a photon (the desired signal), or by thermal energy or electron tunneling (unwanted background noise). The unwanted background noise produced by thermally generated electron-hole pairs and/or electron tunneling, together with false counts due to defective microcells, are collectively referred to as the SiPM’s ‘dark count’.
To eliminate a conventional SiPM’s need for an external digitizing ASIC, the digital silicon photomultiplier developed by Philips equips each individual avalanche photodiode with its own 1-bit on-chip ADC (Analog to Digital Converter) in the form of a CMOS inverter. Each microcell that experiences avalanche breakdown therefore produces its own digital output that is captured, along with the digital outputs from all other triggered microcells, by an on-chip counter. The Philips digital SiPM therefore converts digital events (photon detections) directly into a digital photon count. As a result, it is capable of achieving significantly better resolution than conventional SiPMs.
To overcome the ‘dark count’ problem associated with conventional SiPMs, each microcell in the Philips digital SiPM is also equipped with an addressable static memory cell that can be used to disable or enable the microcell. Microcells that show high dark count levels can therefore be prevented from contributing false counts to the SiPM’s output. This facility allows the Philips’ digital SiPM to achieve better signal-to-noise ratios than conventional devices. Because defective microcells in the array can be disabled, it also helps to improve production yield.

New Melanoma Radioactive PET Imaging Agent Discovered
A collaboration of Australian scientists has identified a new imaging radiotracer as an excellent PET contrast agent for melanoma in laboratory mice. The so called [18F]N-(2-(Diethylamino)ethyl)-6-fluoronicotinamide is now scheduled to begin clinical trials sometime next year, 
according to the press release by the American Chemical Society.
From the abstract in Journal of Medicinal Chemistry:
The high melanoma uptake and rapid body clearance displayed by our series of [123I]iodonicotinamides prompted the development of [18F]N-(2-(diethylamino)ethyl)-6-fluoronicotinamide ([18F]2), a novel radiotracer for PET melanoma imaging. Significantly, unlike fluorobenzoates, [18F]fluorine incorporation on the nicotinamide ring is one step, facile, and high yielding. [18F]2 displayed high tumor uptake, rapid body clearance via predominantly renal excretion, and is currently being evaluated in preclinical studies for progression into clinical trials to assess the responsiveness of therapeutic agents.

Optoacoustics Surgical Communication System for Working in an MRI
Interventional MRI procedures, where the surgeon or radiologist is located at the gantry, often require creative communication skills with the technicians in the control room. The problem is that you can't use conventional headsets because of the magnetic field, which not only interferes with the electronics inside but can also present a danger by sucking the headphones into the tunnel. In addition, the MRI machine itself can be quite noisy. To overcome these problems, Optoacoustics, out of Or-Yehuda, Israel, has developed a nonferromagnetic communication system based on specialized transducers and fiber optic headphones which stay clear of the B-field. So now everyone can wear headsets, and even the patient can listen to music or speak to the surgeon.
Features from the product page:
Fiber Optical Headset: Self-hearing and equipped with slim ear defenders (patent-pending).
FOMRI II Microphone: The industry standard for MRI environments, with real time adaptive noise cancelling.
Optical Switching Unit: Worn by each staff member to enable instant control.
Electro-Optical Unit: Robust heart of the IMROC system.
Mixing & Control Console: Enables six-channel communications management from the control room.
Stereo Sound System: IMROC features a MP4 stereo entertainment system to make patient comfort complete.

vProtect Luminal Shield Stent System Wins EU Approval
Here's a new device designed to improve coronary artery luminal diameter. The European Union just granted approval to Prescient Medical (Doylestown, Pennsylvania) to market its vProtect Luminal Shield catheter for treatment of coronary lesions in patients with symptomatic ischemic heart disease.
The vProtect™ Luminal Shield is designed to minimize arterial injury and its consequences, allowing the vessel to regain and maintain healthy physiological function. The device is a low radial force, thin-strut, self-expanding nitinol mesh, or “Shield” that is designed specifically for softer plaques.The vProtect™ Luminal Shield recently completed phase 1 first-in-human trials for the treatment of de novo obstructive coronary lesions. The Shield is also being evaluated in an investigator-sponsored study known as the SECRITT I (Santorini Criteria for Investigating and Treating Thin Capped Fibroatheroma) trial for the treatment of vulnerable plaques, and a separate study is planned to evaluate use of the Shield in patients with acute coronary syndromes (ACS). A second Prescient Medical product, the vPredict™ Optical Catheter System, is being developed for the detection of vulnerable plaque. It will be evaluated in tandem with the vProtect™ Luminal Shield in the PRESCIENT (Predictive use of Spectroscopic tissue Classification In Evaluating a Novel Treatment) trial, an ambitious study designed to evaluate the detection and prophylactic treatment of vulnerable plaques.
Here's Patricia Scheller, CEO of Prescient Medical discussing the approval of vProtect on FOX Business:

IsoFlow Catheter Helps Target Tumor During Chemo Infusion
Current methods of delivering chemotherapy and chemoembolization agents have trouble limiting the affected parts of the organ to just the area around the tumor. Dana Blankenhorn, who now blogs at SmartPlanet.com, is reporting that Vascular Designs Inc. out of San Jose, CA 
has received FDA clearance for its IsoFlow infusion catheter that can occlude a section of vasculature, while allowing blood to continue to perfuse through the catheter itself. Once occluded, the chemo agents can be delivered peripherally to the isolated section, while blood is shunted past uninterrupted.
More details from the product page:
The IsoFlow catheter enables sideways perfusion, which gives you the ability to push specified fluids both into side branch and angiogenicly formed vessels, letting medications reach an isolated area in a highly targeted and concentrated fashion. With IsoFlow's unique design, fluids can reach areas that could not previously be treated directly.IsoFlow is inserted with a guide wire and catheter for precise positioning within a patient's body. Once in place, both of IsoFlow's balloons are simultaneously inflated using radiopaque fluid via a single inflation lumen. Physician-specified fluid is introduced through the infusion lumen or the guide wire lumen via the one-way stopcock connection. The mixture of infusion and radiopaque agents is then delivered to the target region between the two balloons. For sideways infusion, the guide wire is retracted to allow blood to bypass the isolated target region via holes in the catheter exterior. Complete removal of the guide wire allows fluid delivery from the distal tip.

MRI Friendly Infusion System Gets US Green Light
IRadimed out of Winter Park, Florida has won FDA 510K clearance for the firm's MRidium 3860+ MRI Infusion System that features Masimo's SET SpO2 monitoring technology.
Clinicians no longer have to remember each time when they get to the door of the MRI to remove their standard hospital SpO2 equipment so that it does not become a dangerous projectile, or risk a patient burn, in the MR environment. IRadimed has innovatively combined two critically needed technologies for the MRI to increase productivity, patient safety, and ease of transport to, from, and within, the MRI.The Innovative MRidium 3860+ MRI Infusion System is the first Non Magnetic IV Pump designed specifically for use in the MRI Environment with Integrated Masimo SET technology.
The MRidium Pump has the ability to work at the 10,000 Gauss magnetic field environment of 1.5 and 3.0 Tesla MR Scanners, and the system includes the remote control ability for adjusting critical medication deliveries and alarm monitoring from outside the MR Scanner room. The safe placement of the pump is of the utmost importance, because these safety-critical Gauss line limits are invisible and different for every magnet design and strength, which makes it difficult to know where the safe limits are in relation to the MR Scanner. The 10,000 Gauss Line is virtually inside the bore of the MR Scanner in many cases, which allows the use of the MRidium Pump in close proximity to the MR scanner.
The MRidium System's remote ability allows clinicians to monitor the infusion progress and make changes to the pump from outside the MR scanner room without having to stop the scan; this provides the ability to adjust or bolus critical medications, such as Propofol, which is commonly used for MR Anesthesia, without interrupting, or unnecessarily delaying, the MR scan.
The New MRidium 3860+ System has a number of key new features which make this MR IV Pump simple and safe to deliver even the smallest of infusions. With rate ranges from 0.1 ml to 1400 ml per hour, the MRidium System is designed to meet all of your infusion needs. Our new 10 digit keypad makes programming a snap, with quick changes at the press of a few buttons. This Smart Infusion System also has an integrated programmable drug library designed for the MRI - making it an indispensible tool for delivery of critical medications such as Dobutamine, Adenosine, Propofol, and Dexmedetomidine. The system also offers a modular second channel which allows for delivery of two medications simultaneously during patient scans. A range of available infusion sets provides the necessary clinical flexibility needed for MRI Infusion. The MRidium 1055 Bypass Infusion set allows clinicians to quickly change over IV sets from the hospital based infusion system without having to disconnect the lines from the patient. The MRidium 1057 Vented Syringe Adapter Set allows for accurate delivery from a syringe using a low priming volume of only 4 milliliters per set.

Zilver PTX Drug Eluting Stent for Peripheral Artery Disease Gets European Approval
Cook Medical has received EU's CE Mark to market the Zilver® PTX® paclitaxel eluting nitinol stent for the treatment of peripheral artery disease in the superficial femoral artery. The paclitaxel, a drug also used in the TAXUS cardiac stents by Boston Scientific, has been licensed from Angiotech. The interesting thing about the Zilver® PTX® is that the paclitaxel is attached to to the nitinol frame without the use of any polymer or other anchoring agent, which avoids leaving any plastics behind in the vessel once paclitaxel dissolves.
From Cook's announcement of the approval:
The CE Mark follows the world's largest-ever clinical trial for a peripheral stent, led by Dr. Michael Dake, professor in the Department of Cardiothoracic Surgery at Stanford University Medical School and medical director of the Cath/Angio Laboratories at Stanford University Medical Center, Palo Alto, California. The data published in the Zilver PTX registry involved 791 patients from Europe, Russia, Canada and Korea and demonstrated highly positive results. Only 8 percent of all patients with de novo (new) lesions needed a reintervention to reopen the artery in the first 12 months — a rate significantly surpassing existing treatments for PAD in the SFA, such as balloon angioplasty and bare metal (non-drug-eluting) stents.Also, specific patient groups that are often very hard to treat, such as diabetics and patients with in-stent restenosis (those treated previously with a noncoated stent), were shown in the trial to benefit from the Zilver PTX. As the trial data indicate, the superior results achieved in the first year have been largely maintained throughout 24 months, an important clinical milestone. In comparisons with other trial data obtained, the Zilver PTX stent showed a reduction in reintervention of between 50 percent and 75 percent, an important patient benefit.

Nanoparticles Traverse Blood-Brain Barrier to Help Improve MRI Visualization
Development of a new brain tumor imaging agent is not an easy task for researchers because such substance has to be not only a good contrast agent, it also has to cross the blood-brain barrier in order to work. Researchers at the University of Washington have now developed fluorescent nanoparticles that can both safely cross the barrier and significantly improve contrast in optical and MRI scans of brain tumors in mice.
Until now, no nanoparticle used for imaging has been able to cross the blood-brain barrier and specifically bind to brain-tumor cells. With current techniques doctors inject dyes into the body and use drugs to temporarily open the blood-brain barrier, risking infection of the brain.The UW team surmounted this challenge by building a nanoparticle that remains small in wet conditions. The particle was about 33 nanometers in diameter when wet, about a third the size of similar particles used in other parts of the body.
Crossing the blood-brain barrier depends on the size of the particle, its lipid, or fat, content, and the electric charge on the particle. Zhang and colleagues built a particle that can pass through the barrier and reach tumors. To specifically target tumor cells they used chlorotoxin, a small peptide isolated from scorpion venom that many groups, including Zhang's, are exploring for its tumor-targeting abilities. On the nanoparticle's surface Zhang placed a small fluorescent molecule for optical imaging, and binding sites that could be used for attaching other molecules.
Future research will evaluate this nanoparticle's potential for treating tumors, Zhang said. She and colleagues already showed that chlorotoxin combined with nanoparticles dramatically slows tumors' spread. They will see whether that ability could extend to brain cancer, the most common solid tumor to affect children.

Carbon Nanotubes Power Stationary CT Scanner
A new CT scanner design, featuring a potentially disruptive technology, has been developed by researchers from the University of North Carolina Hospitals, Siemens, and Xintek (Research Triangle Park, NC). The system, being prototyped by a joint venture of Siemens and Xintek, called XinRay, uses a distributed X-ray source made out of carbon nanotubes may replace contemporary machines that have a single source spinning gantry. Because one can trigger the nanotubes to fire instantaneously without any perceivable warm up time, it is possible to achieve high resolution volumetric images of even moving organs.
MIT Technology Review reports:
Instead of a single tungsten emitter, the UNC team uses an array of vertical carbon nanotubes that serve as hundreds of tiny electron guns. While tungsten requires time to warm up, the nanotubes emit electrons from their tips instantly when a voltage is applied to them...The new machine turns multiple nanotube emitters on and off in sequence to take pictures from different angles without moving. Because the emitters turn on and off instantaneously, says Daniel Kopans, director of breast imaging at Massachusetts General Hospital, the system should be able to take more images every second.
This faster exposure, Kopans says, should reduce blur, much as a high-speed camera captures ultrafast motion. Zhou and his colleagues have been able to take breast images at nearly twice the resolution of commercial scanners, using 25 simultaneous beams in a few seconds.
