    摘要： An imaging system including an integral computed tomography and interventional (CT/I) system that includes a large-area detector configured to acquire projection data corresponding to a field of view of the system from one or more view angles is presented. The system includes a computing device operatively coupled to the CT/I system and configured to process the acquired projection data to generate a 2D projection image in real-time, a 3D cross-sectional image of a region of interest in the subject, a combined image using the 2D projection image and the 3D cross-sectional image and/or control selective generation of the 2D projection image, the 3D cross-sectional image and/or the combined image based on one or more imaging specifications. The system also includes a display operatively coupled to the computing device and configured to display the 2D projection image, the 3D cross-sectional image and/or the combined image based on the imaging specifications.

    摘要： A CT system includes a rotatable gantry having an opening for receiving an object to be scanned, at least one x-ray source coupled to the gantry and configured to project x-rays toward the object, a detector coupled to the gantry and having a scintillator therein and configured to receive x-rays that pass through the object, and a generator configured to energize the at least one x-ray source. The system includes a controller configured to energize the generator to project a first beam of x-rays toward the object from a first focal spot position of an anode, the first beam of x-rays having a ray traversing a path through the object, acquire imaging data from the first beam of x-rays, position the at least one x-ray source such that a second beam of x-rays projected from a second focal spot position of the anode has a ray directed to traverse the path through the object, the second anode focal spot position different than the first anode focal spot position, energize the generator to project the second beam of x-rays toward the object, and acquire imaging data from the second beam of x-rays.

    摘要： Systems and methods are provided for acquiring and reconstructing projection data using a computed tomography (CT) system having stationary distributed X-ray sources and detector arrays. In one embodiment, a non-sequential activation of X-ray source locations on an annular source is employed to acquire projection data. In another embodiment, a distributed source is tilted relative to an axis of the scanner to acquire the projection data. In a further embodiment, a plurality of X-ray source locations on an annular source are activated such that the aggregated signals correspond to two or more sets of spatially interleaved helical scan data.
