Method and device for predicting tumor image following radiotherapy

Abstract

A method for predicting a tumor image following radiotherapy comprises the steps in which: an image processing device receives a computed tomography (CT) image of a patient, radiotherapy area information, and radiation dose distribution information; the image processing device inputs the CT image of the patient, the radiotherapy area information, and the radiation dose distribution information to a generative model; and the image processing device generates a cone-beam computed tomography (CBCT) image of the patient following radiotherapy on the basis of output values of the generative model.
