Abstract
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.
