Patent ID: 7881510

Claim:
An apparatus for forming an image of a body of a patient comprising: an energy source which emits energy that passes through the body or which causes the body to emit energy; at least one detector element which receives the energy which has passed through, or originated within the body; a computer with a memory in communication with the detector element which stores in the memory angular and timing information relative to the body regarding the energy; and means for obtaining additional angular and timing information relative to the body regarding the information including the computer-generated steps from a computable readable medium of: acquiring time resolved projective data, either in a sparse manner or in a highly sampled manner, depending on which acquisition aspect of the patient is to be reduced; interpolating either along a circumferential direction or along a temporal direction of the sparsely sampled data, the interpolation direction being determined by a relative k-space sampling density; applying data filtering either along the circumferential direction or along the temporal direction for highly sampled data, the filtering direction being determined by the relative k-space sampling density; compiling a full radial sampling set from the filtered or interpolated data; and submitting the sampling set for reconstruction.
