<P>PROBLEM TO BE SOLVED: To provide a simple, safe and high-accuracy visceral fat measurement device by achieving an impedance CT method for measuring biological impedance of a measurement target with high accuracy. <P>SOLUTION: An impedance distribution of a section calculated from an electrode group annularly disposed on the periphery of the measurement target by use of a four-electrode method is converted into a probability density distribution, and the calculated impedance distribution is approximated by a mixture distribution between a probability density distribution related to a fat portion and a probability density distribution related to a non-fat portion. A fat rate can be estimated from the optimized mixture distribution. <P>COPYRIGHT: (C)2012,JPO&INPIT |
