The present invention provides a body tissue location measurement system in which a wide range and clear ultrasonic image can be obtained without distortion due to respiration through the effective use of an ultrasonic element, making it possible to measure a body tissue location in a minimally invasive manner with high accuracy.To achieve this, a body tissue location measurement system for identifying a location of a target body tissue by means of ultrasonic waves includes: a plurality of ultrasonic elements (101) closely attached to different parts of a body surface； an external sensor (103) for measuring a position of the ultrasonic elements (101)； an ultrasonic propagation model holding unit (105) for holding an ultrasonic propagation model； an ultrasonic propagation time calculation unit (106) for calculating an ultrasonic propagation time based on the ultrasonic model and the ultrasonic element position； an ultrasonic image configuration unit (104) for configuring an ultrasonic image from the ultrasonic propagation time and an ultrasonic signal received from each element； and a target body tissue location calculation unit for calculating a location of a target body tissue from the ultrasonic image.
