Bioimpedance measurement device and method

A system for determine muscle mass of a subject, the system comprising:

• a radiographic imaging system configured to acquire a radiographic image of the subject;
• a bioimpedance measurement apparatus, comprising:
• a plurality of electrodes configured to be placed on respective skin portions of a subject;
• at least one temperature sensor probe configured to be placed on a respective skin portion of the subject and to generate a signal indicative of a temperature of the skin portion the at least one temperature sensor probe is placed on;
• at least one moisture sensor probe configured to be placed on a respective skin portion of the subject and to generate a signal indicative of a moisture level of the skin portion the at least one moisture sensor probe is placed on;
• and
• an electronic module configured to:
• determine an impedance between at least two of the plurality of electrodes,
• receive from the at least one temperature probe the signal indicative of the temperature of the skin portion the at least one temperature sensor probe is placed on and determine the at least one temperature of the skin portion the temperature sensor probe is placed on,
• receive from the at least one moisture sensor probe the signal indicative of the moisture level of the skin portion the at least one moisture sensor probe is placed on and determine the moisture level of the skin portion the at least one moisture sensor probe is placed on, and
• determine a bioimpedance of the subject based at least in part on the determined impedance, temperature, and moisture level;
• and
• a processor configured to:
• receiving from the radiographic imaging system image data representing the acquired image;
• receiving from the electronic module the determined bioimpedance;
• and
• determining a muscle mass of the subject based at least in part on the image data and the determined bioimpedance.

A method of bioimpedance measurement, comprising:

• measuring an impedance between two skin portions of a subject;
• measuring a skin temperature of the subject;
• measuring a skin moisture level of the subject;
• and
• determining a bioimpedance of the subject based at least in part on the measured impedance, temperature, and moisture level.
