In this set-up, the reflection response of the abdominal wall phantom is recorded by means of the sampling oscilloscope. (b) Transmitter and receiver antennas in order to radiate electromagnetic waves and receive the reflection signal from the abdominal wall phantom. (c) Abdominal wall phantom in front of the transmitter and receiver antennas.
