    摘要: An apparatus includes a portion that moves along a guided path and a displacement gauge that outputs readings based on the portion's position on the guided path. The apparatus additionally includes an intermediate limit switch that is activated in response to the portion being moved to an intermediate position on the guided path. The apparatus also includes a processing device configured to calibrate the apparatus based on a first reading corresponding to a first position on the guided path and a second reading corresponding to a second position on the guided path. The processing device verifies the calibration based on a third reading corresponding to the intermediate position.

    摘要: An apparatus and method for determining optimized path traversal in a radiation delivery system is described. In one embodiment, determining an optimized path traversal in a radiation delivery system involves providing a plurality of spatial nodes used in a treatment plan, where each of the plurality of spatial nodes represents a position of a radiation source made available to the treatment plan for delivering radiation to a target, identifying a number of unused spatial nodes, from among the plurality of spatial nodes, at which radiation is not delivered according to the treatment plan, and skipping travel to one or more of the unused nodes by the radiation source when administering the treatment plan. Other embodiments are also described.

    摘要: Tracking a pathological anatomy within a patient's body is described. A data model of a skin surface of the patient's body may be acquired using light reflected from the skin surface. The data model can be matched with skin surfaces reconstructed and/or interpolated from four-dimensional diagnostic imaging data, such as 4D CT data, to determine a temporal phase of the patient's respiratory motion. The identified temporal phase may then be used in conjunction with the diagnostic imaging data to identify a location of the pathological anatomy within the patient's body.

A data model of a skin surface of the patient's body may be acquired using light reflected from the skin surface. The data model can be matched with skin surfaces reconstructed and/or interpolated from four-dimensional (4D) diagnostic imaging data, such as 4D CT data, to determine a temporal phase of the patient's respiratory motion. The identified temporal phase may then be used in conjunction with the diagnostic imaging data to identify a location of the pathological anatomy within the patient's body.

    摘要: A method and system is presented in image-guided radiosurgery for determining the measure of similarity of two digital images, for example a 2D x-ray image and a 2D DRR synthesized from 3D scan data. A two-dimensional array of pixel values of a difference image may be formed by subtracting each pixel value of the second image from the corresponding pixel value of the first image. The pattern intensity function may be constructed by taking the summation of functions of the gradients of the difference image. The neighborhood R may be defined so as to allow the gradients of the difference image to be considered in at least one direction.
