摘要： PROBLEM TO BE SOLVED: To provide an operator with operational information on pressurization to obtain proper elastic images. SOLUTION: This ultrasonic diagnostic equipment, which measures displacement values in each part based on two tomograms measured at different times by applying an external force by a pressurizing means to a subject, calculates an elastic modulus in each tissue based on the measured displacement data in each part, and displays the produced elastic images on a display means, is provided with a pressure determination means which determines whether the pressurizing operation by the pressurizing means has been properly performed or not by analyzing the displacement data. As a result, the displaying of the determination result by the pressure determination means on the display and the outputting through voice enable the operator to quickly adjust the pressurizing means to obtain proper elastic images.
