CNR of different SOI, line plot of brightness across tensor tympani muscle. a Contrast to noise ratio (CNR) of structures of interest (SOI), before and after staining. SOI: LML = lateral malleal ligament. AL = annular ligament. SM = stapedius muscle. TTM = tensor tympani muscle. TM = tympanic membrane. b Line plot of brightness through tympanic membrane over a distance of approximately 3 mm (depicted in Fig. 3b), before and after staining. Compare the visible peak in the stained plot to the not visible peak in the unstained plot. Pixel brightness = 8-bit grayscale, 0–255
