Figure 6From: Contrast-noise-ratio (CNR) analysis and optimisation of breast-specific gamma imaging (BSGI) acquisition protocolsExample of CNR measurement in patient data. Three patients with hotspots for which CNRmax ≤ 2.5 when the acquisition time is reduced to 2 min. The dotted line corresponds to the background ROI used, and the solid line marks the hotspot of interest. The numbers shown correspond to the CNRmax within the ROI.Back to article page
