Figure 2: Example during a cystoscopy using the SPIES Chroma mode (right) in a side-by-side dual view with the unprocessed white light image (left). The light intensity, plotted as the yellow overlay in the image is measured at the red line location in the image. Sharp demarcations are clearly visible in the right image as well as in the plotted graph that shows larger fluctuations on the right side caused by larger contrast variations.
