First Claim
Patent Images
1. A puncture difficulty evaluating device, comprising:
- an ultrasonic transmitting section that irradiates a measurement point of a specimen with an ultrasonic pulse;
an ultrasound receiver section that receives the ultrasound backscattered at the measurement point and determines an integral of the power of the ultrasound over a predetermined angle range; and
a parameter generating section that generates a parameter indicating the difficulty of puncture in the measurement point based on the integral determined in the ultrasonic receiver section.

Abstract
The present invention aims to provide a puncture difficulty evaluating device which can readily evaluate the difficulty of puncture in a measuring point. To this end, a puncture difficulty device receives the ultrasound backscattered at the measurement point, determines an integral of the power of the ultrasound over a predetermined angle range, and generates a parameter indicating the difficulty of puncture in the measurement point based on the determined integral.
