キーワード:optical flow, linear regression, lung cancer, radiotherapy

During lung cancer with radiotherapy, the radiation delivered to healthy tissues around the tumor need to be minimized which is difficult because of the breathing motion and the treatment machine latency. This work presents a new method for predicting chest images from limited information based on multiple points position tracking and prediction through optical flow and linear models.
