ULTRASONIC DIAGNOSING DEVICE

摘要

Enabled is to measure the pressure distribution in the surface of an ultrasonic probe, directly. Piezoelectric sensors having a piezoelectric thin film formed over a film-shaped substrate are arranged in an array shape on the surface of the ultrasonic probe, and a sensor output signal processing unit outputs, on the basis of the output signals coming from individual piezoelectric sensors (S1, S2, - - -, and S9), the pressures measured on and coming from the individual piezoelectric sensors, to an image processing unit. This image processing unit generates a histogram of the pressures on the piezoelectric sensors (S1, S2, - - -, and S9), and outputs the histogram together with ultrasonic tomographic images obtained against an X-axis of the piezoelectric sensor arrangement and a Y-axis of the pressure, to a monitor.
