From: Assessment of the axial resolution of a compact gamma camera with coded aperture collimator
The CNR profiles over the distance used for reconstruction for a selection of source positions: the semi-transparent red line of squares and the blue line of triangles show the CNR profiles of MURA Decoding and 3D-MLEM reconstruction. The Gaussian curves with offset, represented by the bold red dotted line (MURA Decoding) and the blue dashed line (3D-MLEM), were fitted to the CNR profiles. These curves serve as the basis for determining the axial resolution, and the corresponding FWHM values are displayed in the top right corner of each graph
