摘要 |
<p>A transmitter (102) irradiates a measurement point of a specimen with an ultrasonic pulse. A receiver (12) receives the ultrasound backscattered at the measurement point, and determines an integral of the power of the ultrasound over a predetermined angle range. A generator (17) generates a parameter indicating the difficulty of puncture in the measurement point, based on the determined integral.</p> |
