November 12, 2009 - Researchers from the University of California, Irvine Medical Center reported that image-guided RapidArc radiotherapy from Varian Medical Systems conformed to the shape and size of a targeted tumor at least as well as dynamic, fixed-beam approaches to IMRT, stereotactic radiosurgery (SRS) or stereotactic radiotherapy (SRT) for treating cancer.

With the combined impact of the Deficit Reduction Act (DRA), the credit crisis, the economic slowdown, and the uncertainty of pending healthcare reform legislation, we have created the perfect storm.

With a patient on the table, an interventional radiologist follows the movement of his catheter through a maze of arterial vessels. As he weaves his catheter through an intricate web of arteries to reach the coronary arteries and the area of interest, he gets constant real-time feedback from the monitors so he can carefully position the catheter to perform the intervention.

There is no doubt that medical imaging procedures save lives. However, one size does not fit all. Because children are three to five times more sensitive to radiation than adults,1 and cumulative radiation exposure can have adverse effects, it is critical for doctors to lower radiation levels when imaging a child.

November 11, 2009 – In a collaborative study between ContextVision AB, Massachusetts General Hospital (MGH), the Center for Medical Image Science and Visualization (CMIV) and SharpView AB, researchers will investigate advanced 3D image filtering as a means of increasing patient throughput and improving image quality in MRI and further enabling dose reduction in CT.
