Bar chart showing the recorded contrast to noise ratio (CNR) values of different radioactivity concentrations for the simulated superficial and deep SLNs (i.e. 15 and 30 mm depth) for a 100 s acquisition time. Error bars represent the standard deviation of the CNR calculation for each node. The dotted line at CNR = 3 represents a threshold value of the Rose criterion of detectability
