    Abstract: A body fat diagnostic apparatus with which fat can be diagnosed safely is provided even in the case where a deep portion of the living body is diagnosed or there are bone tissues outside the measurement region. The body fat diagnostic apparatus is formed of: a probe 2 for emitting ultrasonic waves both for applying heat and for diagnosis; and an ultrasonic wave velocity change analyzing unit 15 for calculating the change in the velocity of ultrasonic waves in the measurement region on the basis of the ultrasonic wave echo signals acquired from the region before and after the application of heat using the probe 2, so that fat is diagnosed on the basis of the calculated change in the velocity of ultrasonic waves.

    Abstract: A body fat diagnostic apparatus, with which a change in the velocity of ultrasonic waves can be measured and fat can be diagnosed while suppressing the effects of a periodical change due to respiration and heartbeats of a subject, is formed of: a process unit for sequentially acquiring ultrasonic wave echo signals for a number of frames so as to form a group of B mode images; a data storage unit for storing the ultrasonic wave echo signals corresponding to the groups of B mode images; a sampling unit for sampling one frame as a standard image and another frame as a comparative image through the calculation of a cross correlation; and a velocity change analyzing unit for forming an image by calculating a change in the velocity of ultrasonic waves on the basis of the ultrasonic wave echo signals corresponding to the standard image and the comparative image.
