Embodiment Construction

[0060] The present invention provides a system for determining adipose body tissue composition and lean body tissue composition of body tissue. The propagating ultrasound is provided into body tissue. A first set of normal reflections of the propagating wave is received at a first measurement site, and a second set of angled reflections of the propagating wave from body tissue is received at a second measurement site. The fatty body tissue depth and optionally the lean body tissue depth are obtained based on the times at which the first set of reflections and the second set of reflections were received. This device requires only two receivers in order to distinguish the depth of fat body tissue composition from lean body tissue composition. The propagation path is simplified by arranging the transceivers to direct the waves towards the tissue.

[0061] The invention is of particular interest for pregnant women who wish to monitor their weight gain, but the invention can also...

Abstract

A system is for determining fat and lean body tissue components of body tissue. A propagating wave is provided into the body tissue. A first set of normally directed reflections of the propagating wave is received at a first measurement site and a second set of angled reflections of the propagating wave is received from the body tissue at a second measurement site. A fat body tissue depth and optionally also a lean body tissue depth are obtained based on the times at which reflections of the first and second sets are received. This arrangement requires only two receivers in order to resolve the depth of the fat and lean body tissue constituents. The propagation paths are simplified by arranging the transceiver to direct a wave normally into the tissue.

Description

technical field [0001] The present invention relates to determining the adipose tissue composition and lean tissue composition of a subject, for example determining the fat to lean ratio or the total mass of body adipose tissue. This fat-to-lean ratio can be the ratio of the thickness of subcutaneous fat to the thickness of muscle, or the ratio of fat mass to muscle mass. One area of ​​interest is monitoring the body composition of pregnant women during pregnancy. Other areas of interest are applications related to the elderly population, or as part of fitness monitoring or diet monitoring. Background technique [0002] Pregnant women often have difficulty deciding the correct amounts and types of foods to eat in order to ensure the health of their children while preventing their own excess weight gain. It is of particular interest to know whether the weight gain is due in part to an increase in adipose tissue at undesired levels, or simply due to expected weight gain duri...
