Method and system for estimation of abdominal fat

Abstract

The disclosure relates to studying physical properties of biological tissues, and for example, to a method and system for indirect estimation of the abdominal subcutaneous fat area and the abdominal visceral fat area. The technical result is reduced complexity and increased accuracy and speed of estimation of the abdominal subcutaneous fat area and the abdominal visceral fat area with portable devices. A method for determining the abdominal visceral fat area and the subcutaneous fat area in a body section in an abdominal region, comprises: using a device with ultra-wide band (UWB) radar applied to the body in the abdominal region, emitting radiation into the body and measuring parameters of reflected radiation; based on the reflected radiation measurement data obtained by the UWB radar, determining the abdominal subcutaneous fat area (ASFA) in the body section, corresponding to the measurement point; acquiring anthropometric data and bio-electrical impedance value of the body; based on the bio-electrical impedance data of the body and the anthropometric data, determining total fat area (TFA) in the body section in the abdominal region; calculating the abdominal visceral fat area (AVFA) in the body section from the determined total fat area and the abdominal subcutaneous fat area.
