    Abstract: A method and apparatus are used to compare an intended treatment plan using a radiation source with a delivered plan. This done by arranging markers at known three-dimensional (3D) positions in a detection reference system between a two dimensional radiation detector configured to acquire images generated by radiation emitted by the radiation source and an area where the radiation source is positioned during a treatment. The positions of projections of the markers on an image detected are determined when the radiation source is at a treatment position in an intended treatment plan reference system. A plurality of lines in the detection reference system are calculated, each line being defined by a 3D position of a marker and a 3D position of a corresponding projection of the marker on the detector according to the image. A 3D position of the radiation source in the detection reference system is inferred based on the calculated lines. If no correspondence between the detection reference system and the intended treatment plan reference system is available, the inferred 3D position is matched with the treatment position to extract the correspondence between the detection reference system and the an intended treatment plan reference system. If the correspondence between the detection reference system and the an intended treatment plan reference system is available, the inferred 3D position is compared with the treatment position.

    Abstract: A computing system determines a full motion range of a target, wherein the full motion range of the target defines an internal target volume (ITV). The computing system identifies a partial motion range of the target, wherein the partial motion range is a subset of the full motion range of the target. The computing system generates a partial-ITV based on the identified partial motion range, wherein the partial-ITV is a volume swept by the target as the target moves through the partial motion range, the partial-ITV being smaller than the ITV. The computing system generates a treatment plan to deliver treatment to the partial-ITV.

    Abstract: A method for making a beam modifier to be used in radiation therapy includes defining a region of interest in a patient that is to receive radiation, with the region of interest being defined using an anatomy coordinate system format. Radiation treatment parameters are defined for the defined region of interest, and correspond to an initial type beam modifier to be coupled to an output of a radiation device. Design data on a beam modifier to be placed on the skin of the patient is generated, with the design data being based on the defined region of interest and the defined radiation treatment parameters for the defined region of interest. The design data is in the same anatomy coordinate system format as the defined region of interest that is to receive the radiation. The design data is treated as a new region of interest.
