In this work, we aim to develop a numerical observer for cardiac motion assessment in cardiac-gated single photon emission computed tomography (SPECT) imaging. In clinical imaging, diagnostic performance of a human observer for a specific diagnostic task is the gold standard of image quality assessment. However human studies are impractical and costly therefore the use of a numerical observer, a mathematical...
In this work we develop a fully five-dimensional (5D) reconstruction approach based on B-spline modeling for cardiac gated dynamic images. The goal is to obtain a single sequence showing simultaneously both cardiac motion and kinetic tracer distribution change over time from one acquisition. The proposed approach is demonstrated in the context of single photon emission computed tomography (SPECT),...
