Fig. 2From: Performance evaluation of a novel multi-pinhole collimator on triple-NaI-detector SPECT/CT for dedicated myocardial imagingAxial (A) and Radial (B) tomographic sensitivity profiles of the MPH-Cardiac collimator system. The axial sensitivity profile was measured at 50Â mm and 100Â mm radial offsets. The reference line of the LEHR tomographic sensitivity is displayed as a dashed purple lineBack to article page
