  • Patent number: 11712582
    Abstract: A radiotherapy system includes X-ray imaging apparatuses that obtain an X-ray image of the patient on a reference plane, and a position determination apparatus. The position determination apparatus calculates parameters of a region estimation model, using, as input data, a reference fluoroscopic image obtained before radiotherapy, and also using, as teacher data, a reference ROI image obtained with respect to the reference fluoroscopic image before radiotherapy. During radiotherapy, the position determination apparatus estimates a region of interest with respect to the X-ray image and a DRR image, based on the parameters and the X-ray image, determines a degree of matching between the X-ray image and the DRR image for the region of interest while virtually changing a relative position/orientation relationship between a CT image and the reference plane, and determines an amount of deviation in position/orientation between the patient and the CT image.

  • Patent number: 11439848
    Abstract: A template matching is performed on two fluoroscopic images by using a template image prepared in advance and a position corresponding to a high matching score is listed as a candidate for the position of a marker 29. From two lists of the candidates of the position of the marker 29, the lengths of common vertical lines for all combinations are calculated. Then, the position of the marker 29 is detected based on the matching score and the common vertical line. Then, based on the detected position of the marker 29, an amount of a proton beam to be irradiated to a target is controlled. Therefore, a tracking target can be accurately detected even when the conditions for X-ray fluoroscopy is severe, e.g., a thick object.
