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.
