摘要： A control driving method for a radiotherapy device is disclosed. The radiotherapy device includes a collimator and a plurality of radioactive sources, wherein the radioactive sources are disposed within a preset angle range in a longitude direction, the longitude direction being a circular direction perpendicular to a central axis of the radiotherapy device, and the radioactive sources are configured to emit beams that intersect at a common focus after being collimated by a collimator. The method comprises: obtaining at least one protection angle range and driving the radiotherapy device such that no beam from the plurality of the radioactive sources within the at least one protection angle range is emitted.

摘要： An example method for a radiation therapy system that includes a movable couch to perform radiation therapy has been disclosed. One method includes based on the X-ray images of an anatomical region of the patient that includes a target volume, reconstructing a digital volume of the anatomical region and based on a user input indicating a location of a patient origin in the digital volume, determining one or more shift values for repositioning the patient origin at an isocenter of the radiation therapy system with respect to a coordinate system. The method also includes obtaining a treatment plan that is based on the location of the patient origin and is associated with the target volume, based on the treatment plan, repositioning the movable couch so that the patient origin is disposed at the isocenter, and while the patient origin is disposed at the isocenter, directing a treatment beam to the patient origin in accordance with the treatment plan associated with the target volume.

摘要： Methods and systems are provided which relate to the planning and delivery of radiation treatments by modalities which involve moving a radiation source along a trajectory relative to a subject while delivering radiation to the subject. An artificial intelligence (AI) agent trained using reinforcement learning (and/or some other suitable form of machine learning) is used to control the radiation delivery parameters in effort to achieve desired delivery of radiation therapy. In some embodiments, the AI agent selects suitable control steps (e.g. radiation delivery parameters for particular time steps), while accounting for patient motions, difference(s) in patient anatomical geometry and/or the like.

摘要： Disclosed herein are systems and methods for real-time monitoring of patient position and/or location during a radiation treatment session. Images acquired of a patient during a treatment session can be used to calculate the patient's position and/or location with respect to the components of the radiation therapy system. One variation of a radiation therapy system includes a circular gantry with a rotatable ring coupled to a stationary frame, a therapeutic radiation source mounted on the rotatable ring, and a patient-monitoring imaging system mounted on the rotatable ring. The patient-monitoring system may have one or more image sensors or cameras disposed on the rotatable ring within a bore region of the radiation therapy system, and may be configured to acquire image data as the ring rotates.

摘要： A method, controller, and system for controlling a radiation dose in radiotherapy of a patient and a computer storage medium are provided. The method includes: irradiating rays to a target area of the patient through a collimator; and keeping, after a source carrier starts to separate from the collimator in a process of controlling separation of the source carrier and the collimator, timing radiation of the rays or calculating the radiation dose of the rays such that the radiation dose of the rays received by the patient is equal to a radiation dose required for the radiotherapy. Therefore, the radiation dose of the rays received by the patient in an entire treatment process may reach the radiation dose actually required during the radiotherapy, thereby improving a radiation dose control accuracy and a treatment effect during the radiotherapy.

摘要： The invention comprises a method and apparatus for tuning a charged particle beam path of a charged particle beam system used to treat a tumor of a patient, comprising the steps of: positioning a two-dimensional charged particle detector in a beam line downstream from a magnet pair; operating windings of the magnet pair at a first power level to generate a first magnetic field; measuring a beam position with the first two-dimensional charged particle detector; adjusting a correction magnetic field by driving voltage of a correction coil at a second power level, the second power level less than five percent of the first power level, where the first magnetic field and the correction magnetic field combine to yield an operational magnetic field; and the steps of measuring and adjusting the correction magnetic field changing the operational magnetic field to adjust a measured beam position toward a target beam position.

摘要： A method enables testing and evaluation of an expert human reviewer or an artificial intelligence (AI) error detection engine associated with a radiotherapy treatment planning process. Intentional errors are introduced into the output of a software module or AI engine that performs a certain step in the radiotherapy treatment planning process. The efficacy of the human or AI reviewer in detecting errors can then be evaluated or tested by determining whether the human or AI reviewer has detected the introduced error.
