In this work, we propose a direct reconstruction approach to determine a sequence of kinetic parametric images from a single gated acquisition, of which the goal is to provide information simultaneously for both tracer kinetics and cardiac wall motion. The parameter images of the different gates are determined jointly using maximum a posteriori (MAP) estimation from all the available image data in...
In our recent work, we demonstrated the feasibility of an image reconstruction procedure for unifying gated and dynamic imaging, which could yield valid kinetic information for discriminating between normal and perfusion defects. Motivated by this success, in this work we investigate a direct reconstruction approach to determine a sequence of gated, kinetic parameter images from a single acquisition,...
In our recent work we developed a reconstruction approach for cardiac gated dynamic images based on B-spline modeling. The goal is to obtain a single sequence showing simultaneously both cardiac motion and kinetic tracer distribution change over time from one acquisition. In this work, we further develop and demonstrate the feasibility of this procedure for perfusion defect detection in gated dynamic...
In previous work we explored a reconstruction approach based on B-spline modeling for dynamic cardiac images from a gated acquisition in single photon emission computed tomography (SPECT), of which the goal is to obtain a single sequence showing both cardiac motion and kinetic tracer distribution change over time simultaneously. In this work we further develop this approach by extending it to reconstruction...
In our previous work we proposed a dynamic image reconstruction procedure for gated cardiac imaging, of which the goal is to obtain a single image sequence that shows simultaneously both cardiac motion and tracer distribution change over time. In this work, we further develop and demonstrate the feasibility of this procedure for perfusion defect detection in gated cardiac imaging. We conduct Fisher's...
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...
