Title:
測定周波数可変超音波映像装置
Document Type and Number:
Japanese Patent JP5873773
Kind Code:
B2
Abstract:
An ultrasonic imaging device includes an ultrasonic probe including a piezoelectric device transmitting ultrasonic waves to a sample and receiving echo waves, an X axis scanner and a Y axis scanner scanning the sample and positions the probe at a scanning position, a frequency controller controlling a frequency of a received signal in accordance with the position of the scanning position, a signal processing unit processing the received signal, and an image generator generating an ultrasonic wave image at the frequency based on an output of the signal processing unit. The frequency controller generates and supplies a burst signal having a predetermined frequency by a burst wave oscillator to the piezoelectric device of the ultrasonic probe to generate the ultrasonic waves having a predetermined frequency.
