Fig. 9.

Samples of phantom comparisons: tomographic slices and corresponding polar plots obtained using a low-dose rest acquisition. Left panel: DNM (3-min acquisition). Right panel: S-SPECT (15-min acquisition). Upper row: male configuration without a defect. Middle row: female configuration with medium-sized breast inserts and with perfusion defects in the septal and lateral walls. Lower row: male configuration with hot liver and without a defect. Images are quite comparable in spite of fivefold shorter acquisition time on the DNM
