Fig. 2From: Appearance of the levator ani muscle subdivisions on 3D transperineal ultrasoundSlices parallel to the plane of minimal hiatal dimensions (2.4 mm between subsequent slices). The image without (left) and with segmentation (right) is displayed for each slice. From A to F the slices are ordered in the caudal-cranial direction. Slice D shows the plane of minimal hiatal dimensions. Segmented structures: pubic bone (PB, grey), puboperineal muscle (PPM, red), puboanal muscle (PAM, orange), pubovaginal muscle (PVM, yellow), puborectal muscle (PRM, green) and iliococcygeal muscle (ICM, blue)Back to article page
