[Problem] To provide an ultrasonic apparatus with which a decision can be made with better precision as to whether or not to apply gain reduction processing to a gain for echo signals. [Means for Solution] An ultrasonic diagnostic apparatus comprises a control circuit executing: a creating function of creating, based on echo signals from first ultrasound transmitted to a subject to be examined, data for a B-mode image having brightness depending upon intensity of the echo signals; a motion detecting function of detecting a velocity value, etc. as information on motion in the subject based on echo signals from second ultrasound transmitted to said subject; and a deciding function of, in a case that the intensity of the echo signals from said first ultrasound is smaller than a first threshold thand said velocity value is equal to or greater than a second threshold th, deciding that a gain for the echo signals from said first ultrasound is a target of gain reduction processing.

Ultrasonic apparatus and method for applying gain reduction

An ultrasonic diagnostic apparatus and a method for controlling the ultrasonic diagnostic apparatus. The ultrasonic diagnostic apparatus includes: a processor for executing by a program: a first calculating function of, based on a first echo signal of first ultrasound transmitted to biological tissue in a subject to be examined, calculating a value relating to elasticity of said biological tissue; and a second calculating function of calculating a value of attenuation of ultrasound in said biological tissue; and a display device on which a first image produced based on a first two-dimensional (2D) color map CMis displayed, wherein said color map CMdefines a display mode according to the value relating to elasticity of said biological tissue and the value of attenuation in said biological tissue.
