The application discloses an image processing method and device and a radiotherapy system, and belongs to the technical field of images. The method comprises the following steps: a first processing mode is used to process a DRR image to be processed, and an updated DRR image is obtained. The first processing mode is an inverse processing mode of a second processing mode. The second processing mode is used to process a first image of a target object collected by an imaging device in a radiotherapy device, and a second image can be obtained. The similarity between the second image and the blur degree of the DRR image of the target object is greater than a similarity threshold. The application can solve the problem of low accuracy of image registration, and can improve the definition of the DRR image, thereby improving the accuracy of image registration.
