Abstract
An ultrasonographic apparatus includes: an ultrasonic probe 1 for transmitting/receiving an ultrasonic wave to/from a patient, means 2 for generating an ultrasonic transmission signal and transmitting it to the ultrasonic probe, means 3 for receiving a reflection echo signal received by the ultrasonic probe; means 4 for re-constructing a form image according to the reception signal processed by the reception processing means; means 5 for re-constructing an elasticity image according to the reception signal processed by the reception processing means; means 7 for displaying the form image and the elasticity image; means 8 for switching between the form image mode and elasticity image mode; and means 9 for performing control so as to selectively acquire the form image and the elasticity image in the measurement period of the elasticity image mode switched by the mode switching means. Thus, it is possible to perform measurement associated with acquisition of both the form image and the elasticity image of the biological tissue and improve the image quality of the form image such as a B mode image and the image quality of the elasticity image such as elasticity ratio and elasticity dis…
