Body Composition Analysis

Abstract

An analyzer determines the amount of body fat on a patient by using a measurement of body impedence is based upon the nature of the conduction of an applied electrical current in the human body. The analyzer has a constant current source circuit for inducing a high frequency low-voltage signal in the body, and magnitude and phase detection circuits for measuring the magnitude and phase shift of the induced signal. 分析仪通过使用身体阻抗的测量来确定患者身体脂肪的量是基于在人体中施加的电流的传导的性质。 分析仪具有用于在体内感应高频低电压信号的恒流源电路，以及用于测量感应信号的幅度和相移的幅度和相位检测电路。
