Figure 1From: Contrast-noise-ratio (CNR) analysis and optimisation of breast-specific gamma imaging (BSGI) acquisition protocolsContrast-detail phantom. Schematic of the contrast detail phantom design. The dimensions of the phantom are 186 mm × 138 mm. Within each row, the separation between the centres of the holes is 23 mm. The separation between the centres of the holes in adjacent rows is 31 mm. The depths of the holes in each row are 1.3, 1.1, 0.9, 0.7, 0.6 and 0.4 cm, respectively.Back to article page
