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.

摘要： PROBLEM TO BE SOLVED: To accurately grasp the positional relation between a tomographic image and a strain elastic image to draw the same in any strain elastic image drawing means. SOLUTION: A position detection means for detecting a three-dimensional position data represented by a magnetic sensor is attached to an ultrasonic probe.

By the use of the detection means, the position data of a search unit when the tomographic image is obtained and that of the search unit when the strain elastic image is obtained are compared to grasp the relative shift of the diagnostic images obtained by the moving distances of the search unit moved when the mutual images are obtained. The pressure quantity to a specimen tissue can be kept constant regardless of an apparatus handler by the use of the three-dimensional position detection means and an examination enviroment not depending on the apparatus handler can be arranged.
