Recently we developed two image reconstruction approaches aimed to unify gated imaging and dynamic imaging in nuclear cardiac imaging, the goal being to obtain an image sequence from a single acquisition which shows both cardiac motion and tracer distribution change over the course of imaging. While both approaches exploit the similarity among the different cardiac gate intervals, they differ in the...
In our recent work, we proposed an image reconstruction procedure aimed to unify gated imaging and dynamic imaging in nuclear cardiac imaging. With this procedure the goal is to obtain an image sequence from a single acquisition which shows simultaneously both cardiac motion and tracer distribution change over the course of imaging. In this work, we further develop and demonstrate this procedure for...
Recently we developed an image reconstruction procedure aimed to unify gated imaging and dynamic imaging in nuclear cardiac imaging. It can yield a single image sequence to show simultaneously both cardiac motion and tracer distribution change over the course of imaging. In this work, we further develop and investigate the feasibility of our gated dynamic imaging procedure for perfusion defect detection...
In this paper we propose an image reconstruction procedure which aims to unify gated imaging and dynamic imaging in nuclear cardiac imaging. As in gated imaging the cardiac cycle is divided into a number of gated intervals, but the tracer distribution for each gate is treated as a time- varying signal as in dynamic imaging. By using both dynamic and motion-compensated temporal regularization, our...
