A system and method for determining fat and lean body tissue components

A system for measuring fat and lean body tissue components of body tissue, comprising:

• a transceiver for transmitting a or more propagating wave normally into the body tissue, and receiving a first set of normally directed reflections of the propagating wave from the body tissue at a first measurement site;
• a receiver for receiving a second set of reflections of the propagating wave from the body tissue at a second measurement site, which is displaced away from the first measurement site;
• a timing arrangement for determining or estimating the times at which reflections of the first and second sets are received;
• and
• a processor, which is adapted to:
• control the transceiver;
• receive a distance between the first measurement site and the second measurement site;
• process the times determined or estimated by the timing arrangement and the distance received, thereby to derive a fat body tissue depth.
