Abstract

The data-sampling speed of cone-beam CT is faster than that of fan-beam CT, so the cardiac image will be more and more perfect in cone-beam CT with the improvement of the reconstruction algorithm. A new scanning framework of double cone-beam, which has improved FDK algorithm is presented, and a method of 3-D cardiac image reconstruction based on the new scanning framework is designed resulting in a better cardiac image quality.
