Proton Computed Tomographic Image Reconstruction from Curved Paths


Computed tomographic image reconstruction has typically focused on X-rays or photons in the body. This has become an increasingly popular way for radiation therapy for cancer treatment. Proton beams are better than X-rays and photons because they are 1) more accurate 2) leave other tissue unharmed 3) lower-cost. However, protons are heavy, thus bend when shot into the body. Therefore, imaging of the beam may not be accurate. There is a large portion of uncertainty in current uses of proton beam therapy and needs to be corrected.


This invention allows radiation specialists to target a certain area of cancer with a lower rate of uncertainty. The algorithm itself can graphically trace the positions of the cancer proton beams as they travel through the body and monitor slight movements of beams.
