Abstract. Vibration-controlled transient elastography (VCTETM) technique is
routinely used in clinical practice to assess non-invasively the liver stiffness
which is correlated to hepatic fibrosis. Adequate use of the VCTETM probe re-
quires the knowledge of the distance between the skin and the liver paren-
chyma. This paper compares two methods to estimate this distance using spatial
variations of the spectral content of ultrasound radiofrequency (RF) lines, ob-
