Are you dreading upgrading your graphics processor yet again just so you can get lost in the alien-infested urban jungle of Crysis 2? Rest assured that the immersive power of these state-of-the-art video processors is now being used for more than just visual pleasure.
A new technique for processing X-rays appears to lower the radiation patients are exposed to during cone beam computed tomography (CBCT) scans by a factor of 10 or more, according to researchers at the University of California, San Diego.
The research is being presented this week at the American Association of Physicists in Medicine's 52nd annual meeting in Philadelphia.
Lead author Xun Jia, a UCSD postdoctoral fellow, based his team's work on recent advances in compressed sensing by developing a CT reconstruction algorithm for graphics processing unit platforms (GPU cards being used for 3D computer graphics, often in video games), thereby increasing computational efficiency to reconstruct a cone beam CT scan in just minutes.… Read more
