Dear Advanced Visualization Insider,
The displacement of organs and tumors during radiation therapy creates a moving target for treatment planners. But researchers from the Virginia Commonwealth University School of Medicine in Richmond, VA, may have come up with a solution.
The VCU team has developed a model that's able to essentially update the pretreatment CT scans with newly acquired planar projection images, allowing for simulation of deformed anatomy. Proof-of-concept tests showed that their simulated deformations were accurate to within a few percentage points of simulated projection radiographs.
Staff writer Eric Barnes was on hand for last month's Computer Assisted Radiology and Surgery meeting in Berlin for the VCU team's presentation, which is the subject of our Insider Exclusive this month.

Another featured article discusses how centralized 3D labs can be cost-effective for imaging facilities with as few as four or five radiologists, according to Dr. Jay Cinnamon of Quantum Radiology Northwest in Marietta, GA. With the rapid evolution of volumetric imaging technology, 3D labs can now be implemented even at community radiology practices, Cinnamon said. You can find our coverage of his presentation at the 2005 International Symposium on Multidetector-Row CT by clicking here.
