Embodiment Construction
[0047] t = 2 L c . . . ( 1 )
[0048] Here, c represents the speed of sound within the tissue, which can be determined as a constant of approximately 1500 m / s when passing through soft tissue. Therefore, the distance L between the probe and the reflective object is calculated according to the time t from when the ultrasonic wave is projected until the reflected echo signal is received. In addition, the reflected echo signal has information on the acoustic properties of the tissue, and thus a tissue information image such as a B-mode tomographic image can be displayed on the monitor based on the reflected echo signal.
[0049] For example, a method is known in which an elastic characteristic representing tissue stiffness is measured using an ultrasonic diagnostic apparatus. The above-mentioned method for measuring elastic prope...
