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.
