Abstract: The disclosure is directed to a radiotherapy system having a treatment device for treating a treatment body part of a patient with a treatment beam arrangement. The treatment device is included with a couch for placing the patient and includes a medical imaging devices for outputting three-dimensional cone-beam computed tomography images to a computer, and a medical imaging x-ray device for generating at least one x-ray image, if the patient is placed on the couch for treatment, and for outputting at least one x-ray image to the computer. The system will output movement control data to control the relative position of the treatment body part relative to the treatment beam if it is determined there is the offset between the position of the treatment body part relative to the bony structure as described by the image data and the position of the treatment body part relative to a bony structure.

Abstract: The invention is directed to a data processing method for determining the consistency of registration of the position of a treatment body part to be treated by radiotherapy with a treatment beam arrangement of at least one position of a treatment beam issued by a treatment device, the treatment body part being a soft tissue part of an anatomical structure of a patient's body and the data processing method being constituted to be executed by a computer and comprising the following steps: g) acquiring CT data comprising predetermined CT information about a position of the treatment body part relative to a bony structure of the patient's body and about a first position of the bony structure relative to the treatment beam arrangement; h) acquiring x-ray data comprising x-ray information about a second position of the bony structure relative to the treatment beam arrangement; i) determining, based on the x-ray data and the CT data, bony structure position first transformation data comprising bony structure position first transformation information about a first transformation between the first position and the second position of the bony structure; j) acquiring CBCT data comprising CBCT information about the position of the treatment body part relative to the treatment beam arrangement or relative to the bony structure; k) determining, based on the CBCT data and the CT data, bony structure position second transformation data comprising bony structure position second transformation information about a second transformation between the first position and a third position of the bony structure relative to the treatment beam arrangement; determining, based on the bony structure position first transformation data and the bony structure position second transformation data, transformation difference data comprising transformation difference information about a difference between the first and second transformations.
