PROSPECTIVE EVALUATION OF TUMOR VISIBILITY FOR IGRT USING TEMPLATES GENERATED FROM PLANNING CT AND CONTOURS

摘要

Plan CT is described, the presence of hole angle template matching algorithm these problems when generating a kind of stimulation therapy time radiograph of dual energy (DRR) to bore under expectedly estimating, therefore visual tumors. The present invention uses the target of template matching quantization " trackability " from different perspectives or direction. The peak value is used to measure tracking ability to side salient angle ratio. As a result the process influences treatment plan. For example, based on should as a result,The position of hole angle when boring under which template of little or no dosage planning cannot be verified, therefore tumour.
