摘要：

Kalman filter using an operator formulation for a moving object in a sequence of images during the radiotherapy for tracking respiratory subject is presented. The algorithm of position processing with a high-accuracy position estimation technique produced real-time and fast position calculations. The position of a few pixels of the moving object because of position was measured successfully. The results suggest that quantitative assessments of the moving marker should be possible with Kalman filter.
