摘要： The present invention, in one form, is an imaging system for generating images of an entire heart. In one embodiment, projection data is collected for a field of view containing only the heart so that the total detector size is reduced. The smaller detector allows the use of a plurality of source-detector pairs so that projection data for an angular coverage of (&pgr;+fan angle) is collected by rotating a gantry significantly less than one complete rotation. Therefore, projection data is collected in significantly less than one cardiac cycle, minimizing motion artifacts.

摘要： A CT Fluoro system having an architecture and algorithms which facilitate increasing the frame rate and providing acceptable image quality is described. Generally, and in one embodiment, the system includes apparatus and algorithms that speed-up image reconstruction and reduce image artifacts that may result from such fast reconstruction. The fast reconstruction is achieved by performing, for example, view compression, channel compression, backprojection with reduced delay, and parallel processing.

摘要： A computed tomography imaging system has a source of radiation and a radiation detector that has an exponential impulse response characterized by a plurality of N components with different time constants. The source and the detector are revolved about an object to be imaged and the output of the detector is sampled periodically to acquire a set of radiation attenuation values, with the values for each revolution being designated as a scan. A recursive filter function is applied sequentially to the radiation attenuation values from a given scan to generate approximated values for variables of the filter function that define residual detector response from the previous scan. A set of filtered attenuation values then is produced by applying the filter function again to the radiation attenuation values from the given scan. The approximated values for variables are used when the filter function is applied to the first radiation attenuation value of the scan. An image is reconstructed from the set of filtered attenuation values.
