    摘要: A method and system for selective resolution improvement in computed tomography (CT) scanning. The method includes receiving scan data representative of a scanned object from a CT scanner and reconstructing the scan data using a first algorithm to create a first set of reconstructed data. A region of interest is identified within the first set of reconstructed data. A portion of the scan data corresponding to the region of interest is reconstructed using a second algorithm to create a second set of reconstructed data. The first set of reconstructed data and the second set of reconstructed data are combined to create combined reconstructed data.

    摘要: A control system for use with an imaging system is provided. The control system includes a rotation sensor coupled to a rotating portion of a gantry of the imaging system. The rotation sensor includes a gyroscope configured to measure a rotation parameter of the gantry. The control system further includes a data acquisition system (DAS) coupled in communication with the rotation sensor and a detector of the imaging system. The DAS is configured to associate projection data from the detector with the measured rotation parameter.

    摘要: A method for scanning a stream of objects includes continuously acquiring raw data of the stream of objects using an X-ray system, that includes a detector. The raw data of the stream of objects is rebinned into at least one two-dimensional sinogram. A leading edge and a trailing edge of a first object of the stream of objects is determined from the at least one two-dimensional sinogram and a three-dimensional image of the first object is reconstructed using the at least one two-dimensional sinogram.

    摘要: A method for generating an image of an object using a scanning system includes performing a first portion of a scan in a first scanning mode to acquire a first dataset, receiving a halt command for a conveyor within the scanning system, decelerating the conveyor to a halt based on the halt command using a conveyor controller, and, when the object is present within an examination region after the conveyor has halted, performing a second portion of the scan in a second scanning mode to acquire a second dataset. The second scanning mode is different than the first scanning mode. The method also includes reconstructing the first dataset using a first reconstruction algorithm and reconstructing the second dataset using a second reconstruction algorithm. The second reconstruction algorithm is different than the first reconstruction algorithm. The image is generated using the first reconstructed dataset and the second reconstructed dataset.
