Abstract
An ultrasonic diagnostic apparatus includes a physical quantity calculator for setting correlation windows to two echo signals obtained by transmission/reception of ultrasound to and from a biological tissue and different in time on the same sound rays and performing a correlation arithmetic operation between the correlation windows to thereby calculate physical quantities related to elasticity of respective regions in the biological tissue, an elastic image data generator for generating elastic image data of the biological tissue with respect to an elastic image forming region of a transmission/reception surface of the ultrasound, based on the physical quantities, a physical quantity average unit for calculating an average of the physical quantities in the elastic image forming region for every frame, a comparator for comparing a value calculated by the physical quantity average unit and a preset average value of the physical quantities, and a notification unit for notifying a result of comparison by the comparator.
