摘要： A radiotherapy device, a computer-implemented method and a computer-readable medium are disclosed. The radiotherapy device includes a radiation source, one or more imaging systems and a controller communicatively coupled to the radiation source and the one or more imaging systems. The radiation source is configured to apply radiation to a treatment region coinciding with a subject according to a treatment plan. The one or more imaging systems are configured to generate image data for the subject. The controller is configured to: determine, based on the image data, a relative distance between a target region of the subject and an organ at risk of the subject, wherein the treatment plan comprises a prescribed dose for the target region; determine a buffer region around the target based at least in part on the relative distance; and generate a control signal for adjusting a radiotherapy treatment in response to determining, based on the image data, that the treatment region is located at least partially outside the buffer region.

摘要： Disclosed herein is a medical device for tracking movement of a region of a patient's body. The region has a range of motion, for example a range of respiratory motion. The device comprises a controller configured to determine a motion of the region based on one or more initial images depicting at least part of the region. The controller is further configured to predict, based on the determined motion, a motion event time at which at least one property associated with the motion or position of the region will meet at least one criterion, wherein the at least one criterion comprises the region being located at a particular point in its range of motion. The controller is further configured to determine, based on the predicted motion event time, at least one subsequent image capture time at which at least one subsequent image should be captured.

摘要： Disclosed herein is a radiotherapy device comprising a source of therapeutic radiation and an imaging system, the imaging system comprising a source of imaging radiation and a detector. The imaging system is switchable between a first configuration and a second configuration wherein, in the first configuration, the imaging system is configured to emit a beam of imaging radiation shaped for a first imaging modality toward the detector and, in the second configuration, the imaging system is configured to emit a beam of imaging radiation shaped for a second imaging modality toward the detector. The detector is of a shape formed by at least a first and a second section, the first and second section intersecting one another, wherein the first section is positioned for receiving the beam of imaging radiation for the first imaging modality, and the second section is positioned for receiving the beam of imaging radiation for the second imaging modality.
