Abstract

The paper discusses the basic problems and algorithms about cardiac CT reconstructions. A method of selectable rotational velocity is presented for periodic heart rate with circular trajectory. The algorithm can perform any cardiac phase reconstruction exactly or approximately to achieve a desirable temporal resolution. Numerical tests show that the method for selectable rotational velocity is superior to fixed velocity in current cardiac CT.
