摘要： In one embodiment, a method is provided for performing computed tomography (CT) imaging. The method includes obtaining EKG gating information from an object and obtaining attenuation measurements from the object utilizing a detector that is rotated in a scan plane around the object. The method further includes performing a first reconstruction based on a first portion of the attenuation measurements that are collected by a first region of the detector, where the first reconstruction is performed independent of the EKG gating information to obtain a first reconstruction data set. A second reconstruction is performed based on a second port of the attenuation measurements that are collected by a second region of the detector, where the second reconstruction is performed based on the EKG gating information to obtain a second reconstruction data set.

摘要： A multi-sector back-off logic algorithm for obtaining optimal slice-sensitive computed tomography (“CT”) profiles. The systems and methods of the present invention improving the temporal resolution of a CT system by checking for Z location errors between sectors and automatically backing-off to an alternative multi-sector algorithm when necessary (i.e., selecting an optimized maximum number of sectors to reconstruct), providing less Z location error. Based upon this Z location error, the systems and methods of the present invention also calculating the maximum number of sectors that should be used for reconstruction “on-the-fly” (i.e., on a per image basis across an entire series of images). These systems and methods utilizing the Recommended Protocol for Cardiac Reconstruction Algorithms.

摘要： A method for image reconstruction and reducing patient dose, and an imaging system for accomplishing these methods, includes selecting a primary phase of a cardiac cycle and calculating compromised phase regions based on a selected compromised phase value. If the image position is located within the primary phase, then an image is generated at the primary phase. If the image position is not located within the primary phase, but is located within a compromised phase region, then an image is generated at the compromised phase region.
