This research program seeks to develop new algorithms to remove contaminating x-ray scatter from diagnostic and therapeutic medical images obtained in modern radiation therapy. Current radiation treatment units use kilovoltage (KV) x-rays for anatomical imaging (ie. cone-beam computed tomography, CBCT) just prior to therapy delivery using a megavoltage (MV) x-ray beam. Therapy and diagnostic imaging applications on these units are currently at a rudimentary level.

该研究项目旨在开发新的算法，以消除现代放射治疗中获得的诊断和治疗医学图像中的污染X射线散射。目前的放射治疗单位使用千伏（KV）X射线解剖成像（即。锥形束计算机断层扫描，CBCT）。这些设备上的治疗和诊断成像应用目前处于初级水平。
