Abstract: A radiation device directs a beam of radiation onto a target. The beam can be adjusted using, for example, a control for setting beam shape and a control for setting beam intensity. The target is supported on a surface that can be adjusted using, for example, a control for setting surface position and a control for setting a speed for moving the surface. Controls are selected to adjust the beam and the surface cooperatively in order to compensate for movement of the target.

Abstract: A control circuit controls real-time administration of a radiation-treatment plan that administers a therapeutic radiation dose to a patient. This includes compensating for a first movement as regards the application setting using a first treatment-administration modality and responding to detection of a second movement by using a second treatment-administration modality that is different from the first treatment-administration modality.

Abstract: A method of treating a region of interest with radiation by taking a three-dimensional image volume of a region of interest of a patient, defining the three-dimensional image volume, determining one or more metrics of the defined three-dimensional image volume and delivering a dose of radiation to the region of interest of a patient based on the one or more metrics.

Abstract: A system according to some embodiments may include a treatment head to emit treatment radiation, a gantry coupled to the treatment head, an x-ray tube to emit imaging radiation, an imaging device to acquire an image based on the imaging radiation, and a support. The support may be coupled to the x-ray tube and to the imaging device, and movably coupled to the gantry for movement independent of gantry.

Abstract: A radiation therapy method that includes directing a beam along a beam path toward a treatment area. Performing a correction process on the beam, the process includes selectively collimating the beam based on a dose that takes into account bremsstrahlung interactions caused by the beam.

Abstract: A system, method, apparatus, and means for delivering treatment fields includes identifying a sequence group. A type of radiation to be applied in a first field of the sequence group is identified. The type of radiation is selected from among primary photon radiation and primary electron radiation. A radiation therapy treatment device is configured, based at least in part on the type of radiation. The first field is then delivered.

Abstract: A method of treating an area of interest that includes delivering a first therapeutic application to an area of interest of a patient based on an initial prescription and automatically monitoring one or more factors, exclusive of a position of the area of interest, that could affect the effectiveness of the initial prescription. Automatically modifying the initial prescription based on the automatically monitoring one or more factors and delivering a second therapeutic application to the area of interest of the patient based on the automatically modifying the initial prescription.

Abstract: A system, method, apparatus, and means for verifying an electron treatment field include positioning an image detector, and operating the image detector to detect an image created by photons generated in the delivery of an electron treatment beam. The image is manipulated to generate a representation of the electron treatment field.

Abstract: A system includes acquisition of first data representing a three-dimensional surface of at least a portion of a patient's body while the patient is in a first position, and acquisition of second data representing at least one internal portion of the patient's body while the patient is in the first position. The acquired data may be used to ensure correct patient positioning during treatment, to verify patient identity prior to treatment, to identify a change in a patient's body that may require revision of an associated treatment plan, and in conjunction with data representing a physical layout of a radiation treatment area to generate a radiation treatment plan.

Abstract: A system includes acquistion of first data representing a three-dimensional surface of at least a portion of a patient'body while the patient is in a first position substantially maintained in preparation for radiation treatment, acquistion of an image of a first internal portion of the patient's body while the patient is substantially in the first position, and determination of whether the patient is properly positioned for radiation treatment based on the first data and the image.
