断装置。[Scope of Claim for Utility Model Registration] (1) In an ultrasonic diagnostic device that employs a frame correlation method for image smoothing, new data and old data of a predetermined point to be diagnosed, as well as surrounding points. An ultrasonic diagnostic apparatus characterized by having a means for comparing new data together and performing frame correlation. (2) The means for performing the frame correlation receives the reflected ultrasound reflected from the subject with an ultrasound probe, and converts the phased reception signal into an analog signal in a reception circuit.
It is converted into digital data by a digital converter, and this digital data is written into the first line memory and the second line memory alternately every time the ultrasonic beam is transmitted and received. The data is read out and written into the first buffer memory and the second buffer memory, and the new data read out simultaneously and the previous frame data read out from the frame memory are input to a frame correlation circuit and correlated. An ultrasonic diagnostic apparatus according to claim 1, characterized in that the ultrasonic diagnostic apparatus is configured as follows. (3) The ultrasonic diagnostic apparatus according to claim 2, wherein the frame correlation circuit comprises a read-only memory (ROM).
