Abstract:
An image reconstruction method for cardiac cone beam CT is provided, in which data acquired as truncated projections using current cardiac flat panel detectors is reconstructed to form a high quality image of a desired cardiac phase. An iterative method is utilized to reconstruct a prior image from all of the acquired truncated data without cardiac gating. Subsequently, a reconstruction method, in which the prior image is utilized in a prior image constrained reconstruction method, is utilized to reconstruct images for each individual cardiac phase. The objective function in such a prior image constrained reconstruction method is modified to incorporate the conditions used in the production of the prior image so that the data truncation problem is properly addressed.
