Figure 11

Displays the variation in SNR (a) and CNR (b) as a function of time. Figures (c–e) displays the mask generated using an empirical threshold of 20 dB for segmenting the signal and background regions required for calculation of SNR and CNR (Eqns 3 and 4). Figure (c) and (d) corresponds to PD image obtained with and without motion correction, respectively.
