Siemens has unveiled the new syngo Dyn 360 software for the Artis zeego robotic C-arm fluoroscope. The software combines images taken during angiograms to create 3D renderings that look more like CT scans.
The new software can do a 360 rotation in six seconds and capture a field of view of 35×25 centimeters. The reduced exposure time leads to less applied radiation, better image quality, and a much shorter time that the patient has to hold his breath during procedures.
The syngo DynaCT 360 software is a further development of syngo DynaCT, a Siemens-developed technology that creates CT-like slice images from the approximately 400 images made during a rotational angiography, and displays them on screen in the angiography suite while the intervention is still in progress. Particularly in the case of unexpected complications during the intervention and also for immediate follow-up, this enables physicians to arrive at a precise diagnosis without needing to transfer the patient to the CT suite.
Compared with syngo DynaCT, syngo DynaCT 360 has a larger field of view: the volume of a patient’s anatomy recorded during a rotation now measures 35 by 25 centimeters. In addition, the new application can record the field of view roughly twice as fast as before, thus reducing motion artifacts on the images. Thanks to the shorter recording time, patients do not need to hold their breath for as long. Additionally the examination requires less contrast agent and patients can be exposed to less radiation.
During therapy, the large field of view offered by syngo DynaCT 360 makes it possible to visualize entire organs, such as the lungs and liver, as well as tumors, including their tumor-supplying vessels. For example, the large field of view is advantageous if the liver is already enlarged, or the patient is adipose. In addition, the high quality of the soft tissue imaging facilitates needle guidance, biopsies or ablations, e.g. by radio frequency or microwave.
