$L(x,y)$ of a fixed prostate tissue section ($\mu \mathrm{m}$) calculated using: (a) thickness reconstruction from CDR considering every pixel independently, and (b) applying a median filter with a window size of a diffraction-limited spot, pixels with SNR $<1$ excluded, (c) thickness reconstruction using frequency-spectral decay, and (d) atomic force microscopy measurements.
