Abstract
The article analyzes the existing algorithms of cardiac imaging reconstructions using multidata segments and derives the ideal data segment conditions. A scheme of selectable velocity scanning is then proposed for cardiac computed tomography with a circular trajectory, which can cover any cardiac phase exactly or approximately to achieve a desirable temporal resolution. Numerical tests show that the selectable source rotational velocity method outperforms the traditional multidata segment algorithms. The proposed method can be also extended into the cases of helical scanning and variable heart rates.
