Quantitative assessment of the breast phantom scanned by dbPET at the five different positions. Line graphs of CNR (A), and CRC (B), and CVB (C) of the breast phantom images for the 5 mm, 7.5 mm, 10 mm, and 1 mm spheres scanned by dbPET at the five different positions are shown. The a, b, c, d, and e on the X-axis correspond to phantom positions of 8 mm, 13 mm, 19.5 mm (depth of 1/8), 39 mm (depth of 1/4), and 78 mm (depth of 1/2, the centre of the detector) below the top edge of the detector
