WIPO Patent Application WO/2016/151705
Kind Code:
A1
Abstract:
Provided are an ultrasound signal receive circuit and a ultrasonic imaging device that are capable of delaying an analogue signal and eliminates residual signals. The receive circuit is provided with: an input line into which an ultrasound signal is input; a delay circuit that is connected to the input line and delays an analog signal; an output line for output from the delay circuit; and a correction unit connected to the output line. The receive circuit is characterized in that the correction unit obtains a third signal by subtracting, from a first signal output from the delay circuit, a second signal obtained by delaying the first signal by a predetermine time and attenuating the signal.
