Ultrasound of normal skin

The authors have used a commercially available real-time sector scanner and a 10-MHz probe with a built-in water path for B-mode imaging of the normal skin. Measurements have been performed in 10 volunteers at 18 sites on the body surface. Normal skin thickness ranges from 1.4 mm at the dorsal aspect of hand to 4.8 mm at the heel. Clinical applications of B-mode imaging of the skin are discussed.
