Measurement Frequency Variable Ultrasonic Imaging Device
First Claim
1. A measurement frequency variable ultrasonic imaging device comprising:
- an ultrasonic probe including a piezoelectric device transmitting ultrasonic waves to a sample and receiving an ultrasonic waves reflected, scattered, and refracted by the sample to output a received signal;
a scanner scanning the sample with the ultrasonic probe and positioning the ultrasonic probe at a predetermined scanning position;
a frequency controller controlling a frequency of the received signal in accordance with the scanning position of the probe;
a signal processing unit processing the received signal; and
an image generator generating an ultrasonic wave image at the predetermined frequency on the basis of an output signal of the signal processing unit.

Abstract
The ultrasonic imaging device includes the ultrasonic probe including the piezoelectric device transmitting ultrasonic waves to the sample and receives echo waves, the X axis scanner and the Y axis scanner scanning the sample and positions the probe at a scanning position, the frequency controller controlling the frequency of the received signal in accordance with the position of the scanning position, the signal processing unit processing the received signal, the image generator generating ultrasonic wave image at the frequency on the basis of the output of the signal processing unit. The frequency controller generates and supplies a burst signal having the predetermined frequency by the burst wave oscillator to the piezoelectric device of the ultrasonic probe to generate the ultrasonic waves having a predetermined frequency.
