GPU Video Game Processors Can Help Reduce CT Scan Radiation

The use of graphic processing unit (GPU) chips commonly utilized in video game systems can reduce radiation exposure during CT scans by speeding up image processing, according to a report from the American Institute of Physics detailing research at UCSD.  By utilizing GPUs in image-guided radiation therapy (IGRT), processing time is reduced 100 times.  By processing images faster, the IGRT procedure takes less time, thus reducing radiation exposure by 36-72 times the current amount.  Reducing radiation is a huge concern as cancer resulting from excess radiation exposure account for approximately 14,500 deaths per year.
