Ultrasound (US) image processing. Panel A: The testis US image obtained during a routinely performed testicular US; Panel B: The contour of the manual segmentation of the testicle in the longitudinal view; Panel C: The exclusion of calibre measurement artefacts and zones with lower echogenicity due to high acoustic impedance differences; Panel D: The final mask of the testicle for the texture analysis
