Patent ID: 8111068

Claim:
A non-transitory computer readable medium storing computer executable instructions operable to perform a method, the method comprising: controlling an imaging apparatus to acquire an image from an object associated with a fiducial; receiving a point source data associated with the fiducial, the point source data being acquired from a first projection data S 1 acquired at a first time T 1 from a first viewing angle θ 1 resulting in a first projected distance r 1 and a second projection data S 2 acquired at a second time T 2 from a second viewing angle θ 2 resulting in a second projected distance r 2 ; computing a point source location based, at least in part, on the point source data, where computing the point source location comprises: determining R res , where R res is the displacement component of a polar coordinate for the point source; and determining θ res , where θ res is the angular component of the polar coordinate for the point source; computing a predicted waveform data based, at least in part, on one or more of the point source location, and the point source data; receiving an observed image data comprising: one or more projection data of a non-Cartesian k-space associated with the object; and an observed waveform data related to a location of the fiducial associated with the object and further associated with the predicted waveform data; and producing a selectively processed observed image data to reduce the effects of rotational motion of the object during image acquisition based, at least in part, on comparing the predicted waveform data and the observed waveform data.
