摘要
Provided is an ultrasonic evaluation device in which there is employed a temperature-sensitive phantom that has a broader band of temperature sensitivity while maintaining transparency. This ultrasonic evaluation device is accommodated in an accommodation box and comprises: a temperature-sensitive phantom provided with a plurality of temperature-sensitive phantom members formed so that temperature-sensitive materials are mixed into transparent phantoms, the temperature-sensitive phantom members having substantially the same shape and having different ranges of temperature sensitivity, and the temperature-sensitive phantom being such that the temperature-sensitive phantom members are positioned symmetrically with respect to the longitudinal center axis of the temperature-sensitive phantom; a sheet light source that radiates planar light perpendicular to the longitudinal center axis; and an image sensor that is positioned on an extension line of the longitudinal center axis and captures images of the temperature-sensitive phantom members that have received ultrasonic radiation. The accommodation box accommodates an ultrasonic output element so that the emission direction coincides with the longitudinal center axis and so that ultrasonic waves are focused at the longitudinal center axis.
