<P>PROBLEM TO BE SOLVED: To provide an ultrasonic diagnostic apparatus capable of performing an IMT (Intima Media Thickness) measurement high in quantitativeness and less in variation by examiners. <P>SOLUTION: The ultrasonic diagnostic apparatus includes: an ultrasonic probe 100 for transmitting ultrasonic waves to a subject and receiving ultrasonic echoes generated by reflection of the ultrasonic waves in the object to output reception signals; a signal processing unit 28 for performing at least envelope detection processing on the reception signals outputted from the ultrasonic probe to generate envelope data; a boundary detecting unit 41 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 image data; and an IMT calculating unit 46 for calculating an IMT of the blood vessel based on the two boundaries detected by the boundary detecting unit. <P>COPYRIGHT: (C)2008,JPO&INPIT |
