用超音波診断装置。[Scope of Claim for Utility Model Registration] (1) In an ophthalmic ultrasound diagnostic device that displays an A-mode image obtained by transmitting and receiving ultrasonic waves, an amplifier that amplifies the echo signal forming the A-mode image and a gain setting. a threshold setting circuit that introduces a gain setting signal given to the amplifier from the amplifier and outputs a threshold signal corresponding to the gain setting signal; and an echo signal amplified by the amplifier as the threshold signal. An ophthalmological ultrasound diagnostic apparatus comprising: a comparator that compares and outputs the comparison output as a peak detection signal. (2) The threshold setting circuit introduces the counting output of a peak counting circuit that counts the number of peak detection signals at the output stage of the comparator, and generates a threshold signal based on this counting output and the gain setting signal. The ophthalmological ultrasound diagnostic apparatus according to claim 1 of the utility model registration claim, which outputs an output.
