Abstract
A method of processing a SPECT image of a region of interest is disclosed. The SPECT image was obtained using at least one gamma detector detecting gamma radiation from the region of interest at multiple detector configurations, and the method includes: obtaining data indicative of the detector configurations and their spatial relationships to the region of interest; determining a resolution level for each of a plurality of directions in each point in the image based on the data obtained; and processing the image based on the resolution levels determined.

-22. (canceled)
An apparatus for imaging a region of interest, the apparatus comprising:
- at least one gamma detector;
- a detection controller configured to control the at least one gamma detector to detect gamma radiation from the region of interest at multiple detector configurations;
- and
- a processor configured to
- reconstruct an image from readings of the at least one gamma detector;
- obtain data indicative of the multiple detector configurations and their spatial relationships to the region of interest;
- determine a resolution level for each of a plurality of directions in each point in the image based on the data obtained;
