Fig. 6From: Performance evaluation of fifth-generation ultra-high-resolution SPECT system with two stationary detectors and multi-pinhole imagingReconstructed SPECT images of the mini Derenzo phantom 850.500 with various activity concentrations (mean ± standard deviation) of 99mTc for a 300 s TPB scan (10 BP). Rod sections marked with the red star were assumed to be the smallest diameter resolved. All images are shown with 6.0 mm slice thickness and 0.35 mm full width half maximum Gaussian post-filterBack to article page
