A system and method of performing prospective and retrospective on-line adaptive radiotherapy. The method includes performing, during a treatment delivery session, delivery of a dose of radiation to an anatomical volume. The method includes detecting, during the treatment delivery session, a current state of the anatomical volume. The method includes predicting a future change in the current state of the anatomical volume during the treatment delivery session. The method includes adjusting, while the anatomical volume is in the current state, the treatment delivery to anticipate the future change in the anatomical volume.

Prospective and retrospective on-line adaptive radiotherapy

A method of calibration in a radiation delivery system. The method including acquiring, using a camera, an image of a radiation beam incident on a phantom, wherein the radiation beam being emitted by a radiation source of the radiation delivery system and the phantom comprising an X-ray luminescent material. The method further including determining a beam pointing offset based on the image. The method further including calibrating a position of the radiation source of the radiation delivery system based on the beam pointing offset and a relative position of the camera with respect to a beam axis of the radiation beam.

Radiation based treatment beam position calibration and verification

A method of operating a radiation apparatus is described. The method includes selecting at least a first angle and a second angle from a set of angles for a first rotation of a gantry of a radiation apparatus. The method also includes generating, using an imaging device mounted to the gantry, a first tracking image of a target from the first angle during the first rotation of the gantry. The method further includes generating, using the imaging device, a second tracking image of the target from the second angle during the first rotation of the gantry.

Online angle selection in rotational imaging and tracking systems

A method of operating imaging and tracking. The method includes determining, for each angle of a plurality of angles from which tracking images can be generated by an imaging device, a value of a tracking quality metric for tracking a target based on an analysis of a projection generated at that angle. The method also includes selecting, by a processing device, a subset of the plurality of angles that have a tracking quality metric value that satisfies a tracking quality metric criterion, one or more angles of the subset to be used to generate a tracking image of the target during a treatment stage, wherein the subset comprises at least a first angle and a second angle that is at least separated by a minimum threshold from the first angle.

Offline angle selection in rotational imaging and tracking systems

A radiation delivery system that includes a gantry to extend along one or more axes. The gantry is to provide a continuous rotation. The radiation delivery system includes a linear accelerator (LINAC) coupled to the gantry. The LINAC is to generate a treatment beam. The radiation delivery system includes a rotary joint coupled to the gantry. The rotary joint provides a physical connection from the LINAC to an external system that is positioned off the gantry. The physical connection is to transport radio frequency (RF) power.

A method and apparatus for radiation treatment planning are described. The method includes receiving a plurality of radiation treatment-planning parameters, and sequentially optimizing the plurality of radiation treatment-planning parameters.

Sequential optimizations for treatment planning

An image guided treatment is performed to treat a target. To perform the image guided treatment, measurement data indicative of target motion is acquired. A timing of one or more x-ray images is determined based on the measurement data. Treatment may be performed on the target using the position of the target.
