PROBLEM TO BE SOLVED: To reduce an impact of a background factor on an ultrasonic CT image and facilitate grasping of the progress of a lesion.SOLUTION: An ultrasonic element transmits an ultrasonic wave to an imaging region of a subject, receives a transmitted wave of the subject of the ultrasonic wave, and acquires a reception signal. An image generation part processes the reception signal, and generates an image indicating the distribution of a predetermined physical property value in the subject. The image generation part generates a standard body temperature conversion image indicating the distribution of a physical property value when the body temperature of the subject is a predetermined standard body temperature using the body temperature of the subject at the time when the ultrasonic wave is transmitted and received.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2018,JPO&INPIT【課題】背景因子が超音波CT画像に与える影響を低減し、病変の進行度の把握を容易にする。【解決手段】超音波素子は、被検体の撮像部位に超音波を送信し、超音波の被検体の透過波を受信し、受信信号を得る。画像生成部は、受信信号を処理して、被検体における所定の物性値の分布を示す画像を生成する。画像生成部は、超音波の送信および受信時の被検体の体温を用いて、被検体の体温が所定の標準体温である場合の物性値の分布を示す標準体温換算画像を生成する。【選択図】図3
