Title:
TRACKING DEVICE FOR RADIATION TREATMENT, POSITION DETECTION DEVICE, AND METHOD FOR TRACKING MOVING BODY
Document Type and Number:
WIPO Patent Application WO/2019/003434
Kind Code:
A1
Abstract:
A control unit 30 comprises a DRR image creation unit 31 that creates a DRR image containing a specified area, a specified area projection unit 32 that creates a projection region image representing the region of the specified area, an identifier learning unit 33 that learns an identifier for recognizing the region of the specified area by executing machine learning using the DRR image and the projection region image as a teacher label image, a specified area region detection unit 34 that detects the region of the specified area by performing identification in an X-ray fluoroscopic image containing the specified area using an identifier learned by the identifier learning unit 33, and an irradiation signal generation unit 35 that transmits an irradiation signal of a treatment beam to a radiation irradiating device 90 when the region of the specified area detected by the specified area region detection unit 34 is included in an irradiation region of the treatment beam.
