Abstract:
1. Method of improving the resolution of SPECT imaging of a region of interest of a biological object comprising: performing a first MRI scan on a biological object to determine a limited field of view (LFOV); moving the region of interest into the LFOV of an MRI imaging system and SPECT imaging system based on the first MRI scan; simultaneously performing a second MRI and first SPECT scan on the LFOV to acquire second MRI data and first SPECT data; generating an adaptive system matrix using average intensities generated from the second MRI and first SPECT data, wherein the adaptive system matrix is defined by where Si,j is the system matrix, where T/B is the target-to-background value, where ξ generating an image of the region of interest in the LFOV using the adaptive system matrix.
