摘要： One embodiment of the present disclosure sets forth a method for determining a movement of a target region using tomosynthesis. The method includes the steps of accessing a first set of projection radiographs of the target region over a first processing window defined by a first range of projection angles, accessing a second set of projection radiographs of the target region over a second processing window defined by a second range of projection angels, wherein the first processing window slides to the second processing window during treatment of the target region, and comparing a first positional information derived from the first set of the projection radiographs and a second positional information derived from the second set of the projection radiographs with the first positional information to determine the movement of the target region.

摘要： The plan CT is described to generate dual energy (DRR) that stimulates the treatment time radiographs in order to prospectively evaluate the angles in which issues for the template matching algorithm are present, and thus the visibility of the tumor. The present invention uses template matching to quantify the “trackability” of the target from different angles or directions. The peak-to-side lobe ratio is used to measure trackability. The results of this process influence treatment planning. For example, based on the outcome, either less or no dose is planned for the angles in which the location of the templates cannot be verified and thus, the tumor.

摘要： A method for determining a position of a target includes obtaining a first image of the target, obtaining a second image of the target, wherein the first and the second images have different image planes and are generated at different times, processing the first and second images to determine whether the target in the first image corresponds spatially with the target in the second image, and determining the position of the target based on a result of the act of processing. Systems and computer products for performing the method are also described.

摘要： A method for generating one or more images includes collecting data samples representative of a motion of an object, acquiring image data of at least a part of the object over a time interval, synchronizing the data samples and the image data to a common time base, and generating one or more images based on the synchronized image data. A method for generating one or more images includes acquiring image data of at least a part of an object over a time interval, associating the image data with one or more phases of a motion cycle, and constructing one or more images using the image data that are associated with the respective one or more phases.
