摘要： A medical imaging system includes image acquisition circuitry, a memory, and a processor coupled to the image acquisition circuitry and memory. The processor executes a physiologic marker program out of the memory. The marker program obtains physiologic marker definitions for events shown in a first dataset image, determines physiologic markers associated with the marker definitions, and superimposes the physiologic markers on a second dataset image that does not necessarily show the event.

摘要： For the purpose of reducing artifacts caused by a scan plane tilted with respect to a rotation plane when a multi-row detector is employed, a j-th detector row which an X-ray passing through a pixel point g(x, y) enters is selected based on the distance Δz from a scan center plane to an image reconstruction plane in a z-axis direction and the position (x, y) of the pixel point g in the image reconstruction plane, and data of the j-th detector row is used to determine the pixel value of the pixel point g, where the scan center plane at a certain view angle is defined as an x-y plane, and a direction normal to the x-y plane, i.e., a detector row direction, is defined as the z-axis direction.

摘要： An imaging system includes an x-ray source coupled to a gantry. The x-ray source generates an x-ray flux, wherein a portion of the x-ray flux becomes scatter radiation. A scatter detector is also coupled to the gantry to receive the scatter radiation. The scatter detector generates a scatter signal in response to the scatter radiation, and a host computer receives the scatter signal.
