Title:
PREDICTION SUPPORT SYSTEM, PREDICTION SUPPORT METHOD, AND PREDICTION SUPPORT PROGRAM
Document Type and Number:
WIPO Patent Application WO/2023/157869
Kind Code:
A1
Abstract:
A support device (20) includes a control unit (21) that predicts an irradiation state with a particle-beam irradiation device. The control unit (21) calculates, by simulation: a first three-dimensional radioactivity distribution obtained by changing, with respect to a reference dose distribution obtained when a particle beam is radiated on a patient state in an irradiation state based on an irradiation condition of the particle beam, at least one of the irradiation state and the patient state; and measurement information obtained by two-dimensionally measuring the first three-dimensional radioactivity distribution. The control unit (21) generates a prediction model predicting the first three-dimensional radioactivity distribution from the measurement information, and irradiates the particle beam according to the irradiation condition of the particle beam. When the control unit (21) obtains a measurement result obtained by two-dimensional measurement, the control unit (21) applies the prediction model to the measurement result to predict a second three-dimensional radioactivity distribution corresponding to the measurement result.
