Title: ULTRASONIC IMAGING DEVICE, ULTRASONIC IMAGING METHOD, ULTRASONIC IMAGING PROGRAM, AND ULTRASONIC CT DEVICE
Abstract:
Provided is an ultrasonic imaging device with which the temperature of a subject containing water and fat can be inexpensively detected. The ultrasonic imaging device pertaining to the invention detects the temperature of a subject that contains water and fat, wherein said ultrasonic imaging device comprises a temperature-dependent-characteristic-acquisition means that acquires a temperature-dependent characteristic of the acoustic velocities at each of a plurality of sites of the subject on the basis of a the water content ratios and the fat content ratios at each of the plurality of sites, a first arrival time acquisition means that acquires a measurement value of a plurality of first arrival times at which ultrasonic waves arrive via a plurality of pathways that pass through the subject, and a temperature determination means that determines the temperatures of the plurality of sites on the basis of the measurement values of the plurality of first arrival times and the temperature-dependent characteristic of the acoustic velocities of the plurality of sites.
