Fig. 2From: Imaging of 212Pb in mice with a clinical SPECT/CTMaximum intensity projection images of the mouse phantom acquired with the preclinical SPECT/CT. Image (A) shows the highest activity concentration imaged, 241 kBq/ml, similar to the activity concentration when the phantom was imaged on the clinical SPECT, without filters applied. Image (B) is from the same acquisition, but with a 2.4 mm filter applied. Image (C) is from an acquisition 24.6 h later, with 49 kBq/ml in the high-activity concentration volumes, with a 2.4 mm filter appliedBack to article page
