ABSTRACT:
An ultrasonic diagnostic apparatus by which highly quantitative IMT (intima media thickness) measurement with little variations depending on examiners can be performed. The ultrasonic diagnostic apparatus includes: an ultrasonic probe for transmitting ultrasonic waves to an object to be inspected and receiving ultrasonic echoes generated by reflection of the ultrasonic waves in the object to output reception signals; a signal processing unit for performing at least envelope detection processing on the reception signals outputted from the ultrasonic probe to generate envelope data; a boundary detecting unit for detecting two boundaries representing intima media of a blood vessel based on difference or differential of values of the envelope data and amounts of change in the values of the envelope data; and an IMT calculating unit for calculating an IMT of the blood vessel based on the two boundaries detected by the boundary detecting unit.
