Live Surface, A Software for Surgeons

August 2nd, 2006 Medgadget Editors Cardiac Surgery, Neurosurgery, Orthopedic Surgery, Surgery, Thoracic Surgery, Vascular Surgery

Computer scientists at Brigham Young University have developed a software that allows surgeons to reconstruct patient’s anatomy in 3-D from an MRI, CT scan or other imaging modalitites with just a “few clicks of the mouse.”

The tool, dubbed “Live Surface” by its creators BYU professor William Barrett and graduate student Chris Armstrong, also has special-effects applications — in similar fashion it can be used to extract a single actor’s performance or inanimate objects from video clips. Click to see video.
“The main goal in developing Live Surface was to give the physician a powerful, practical tool that can be used interactively,” said Barrett, explaining that existing software and techniques that are used to give doctors a look at a patient’s anatomy are either too simplistic or take too long to be of immediate use. “A program like this has to be incredibly fast and very interactive, or else it’s very frustrating for the user, who currently has to go get a sandwich and come back before he has what he wants.”
Live Surface has the additional benefit of allowing users to easily isolate “tricky” anatomy such as soft tissue –blood vessels, hearts and muscles — that a lot of other techniques can’t readily extract, said Barrett. Click to see video.
“The hard stuff (meaning bones) is easy to see using traditional methods, but even there, the simpler techniques sometimes overestimate, underestimate, or fuse joints, whereas Live Surface neatly and accurately separates them,” said Barrett. “Our program also provides more robust isolation of soft tissue, which is quite a breakthrough.” Click to see video.
The BYU software works by extracting information from data collected in 3-D volumes – CT scans, MRIs or 3-D ultrasounds. With a click and drag of the mouse, a user identifies the object he wishes to extract. Next, he identifies those portions of the data that surround the object. Immediately, the desired object is extracted from the data. Click to see video.
“This is the object I want, and this is not the object I want. And in less than half a second, it pulls the object you want out of the data,” said Armstrong, who will present the computer science research behind Live Surface at the International Workshop on Volume Graphics July 31 in Boston. “It’s really that simple.”
The program works in a rapid manner because it extracts the object using a hierarchical algorithm, or set of mathematical rules, that tells the computer to eliminate irrelevant information in broad, coarse cuts. Once the bulk of unwanted data is gone, the computer is free to make more refined calculations more quickly.
“It’s how you might envision cutting a toothpick out of a redwood tree,” said Armstrong. “You’d start with a chain saw and make very big cuts at first. By the end you’d use a knife to delicately shape the toothpick. Instead of ‘cuts’ our program intelligently identifies shapes. As you refine more and more, that shape becomes more exact.”
After a surgeon had extracted a 3-D image of a person’s heart or brain, for example, the image could then be projected onto the patient’s body, fitted to create a road map for the surgeon as he operated. Additionally, doctors could use the tool to make better diagnoses after visualizing a patient’s organs from multiple angles or do a better job of locating cancerous tumors.
