Description:
This study evaluated the relative contributions of septal penetration (SP) and scatter correction (SC) to 3D-OSEM reconstruction using 3 different detector response models.
Clinical Relevance:
In these phantom studies, including septal penetration with the geometric component of an 123I detector response model contributed the same percent improvement to cardiac CNR (25-35%) as SC. A smaller PSF model may reduce reconstruction time while providing adequate compensation for detector response.
Partners in Research:
INVIA Medical Imaging Solutions and the University of Michigan collaborated on this research.
