Abstract:
1. A method for performing computed tomography (CT) imaging, the method comprising: obtaining physiologic gating information from an object; obtaining attenuation measurements from the object utilizing a detector that is rotated in a scanned plane about the object and that detects x-rays passing through the object; performing a first reconstruction of the object based on the attenuation measurements collected by a first narrow angle full field of view region of the detector having selectively activated detector elements to obtain a first reconstruction data set, the first reconstruction being performed independent of the physiologic gating information; and performing a second reconstruction of the object based on attenuation measurements collected by a second wide angle full field of view region of the detector having at least some different selectively activated detector elements and based on the physiologic gating information to obtain a second reconstruction data set.
