Abstract
Methods and systems are provided for calibrating a nuclear medicine imaging system having more than 5 detector heads. In one embodiment, a method includes obtaining residual center of gravity determinations corresponding to each of a plurality of detector units based on point source projections acquired over a series of detector unit rotational steps, obtaining center of gravity determinations for each of the plurality of detector units based on point source projections acquired over a series of detector unit sweep angles, obtaining a fit of the center of gravity determinations for each of the plurality of detector units, and determining a sweep offset for each of the plurality of detector units based on the residual center of gravity determinations and the fit of the center of gravity determinations for each of the plurality of detector units. In this way, a sweep axis zero degree position for each of the plurality of detector units is determined.
