Model saves time, radiation by simulating anatomic changes during radiotherapy

By Eric Barnes

Organs and tumors can twist, turn, and deform substantially during radiotherapy, creating a moving target for treatment planners seeking to avoid irradiating normal tissue. One solution, a full CT scan before each treatment, is both time- and radiation-intensive. But what if doctors could simply "update" the pretreatment scan with a few newly acquired planar projection images? Researchers from Virginia built and tested a model to do just that.

Interventionalists see safer RFA with coregistered laparoscopic US, CT

By Eric Barnes

BERLIN - Percutaneous radiofrequency ablation (RFA) and other minimally invasive interventions have become increasingly popular. But the interventionalists who perform them often end up working in the dark, as the CT or MR image they've placed across the room bears little resemblance to the laparoscopic ultrasound images used to guide the RFA needle. Researchers may have found a solution, according to a presentation at the Computer Assisted Radiology and Surgery (CARS) meeting.

CARS suite of the future sees key role for image-guided intervention

By Eric Barnes

BERLIN - In Wednesday's opening session of the 19th International Congress of Computer Assisted Radiology and Surgery (CARS), Dr. Michael Vannier set forth his vision of the interventional suite of the future, and touched on the powerful forces shaping its development.

Researchers take aim at next-generation image-guided surgery systems

By Eric Barnes

Just as virtual guided imaging is beginning to pay off in diagnostics, a group of techno-wizards have taken aim at the next goal: putting powerful, intuitive, real-time image guidance systems into surgeons' hands.
