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.
