  • Publication number: 20180289982
    Abstract: A method of sequential monoscopic tracking is described. The method includes generating a plurality of projections of an internal target region within a body of a patient, the plurality of projections comprising projection data about a position of an internal target region of the patient. The method further includes generating external positional data about external motion of the body of the patient using one or more external sensors. The method further includes generating, by a processing device, a correlation model between the projection data and the external positional data by fitting the plurality of projections of the internal target region to the external positional data. The method further includes estimating the position of the internal target region at a later time using the correlation model.

  • Publication number: 20140371513
    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.
