Abstract: [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 th1 and said velocity value is equal to or greater than a second threshold th2, deciding that a gain for the echo signals from said first ultrasound is a target of gain reduction processing.

Abstract: 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 CM1 is displayed, wherein said color map CM1 defines a display mode according to the value relating to elasticity of said biological tissue and the value of attenuation in said biological tissue.

Abstract: Ultrasonic diagnostic apparatus capable of improving visibility of a low-brightness region in a B-mode image while maintaining visibility of a high-brightness region, a processor produces a first B-mode image and a second B-mode image BI2, locates a first region R1 in the first B-mode image having lower brightness than a surrounding region, and produces a combined image I in which an image BI2a of a second region R2 at a position in the second B-mode image BI2 corresponding to a position of the first region R1 is combined into the position of the first region R1 in the first B-mode image for display on a display 8. The first B-mode image is obtained using a first condition group, and the second B-mode image BI2 is obtained using a second condition group defined so that brightness of the second B-mode image BI2 is higher than that of the first B-mode image.

Abstract: A processor in an ultrasonic diagnostic apparatus controls an ultrasonic probe 2 to transmit a first ultrasonic beam to a first region A1, transmit a second ultrasonic beam to a second region A2, and transmit a third ultrasonic beam to a third region A3, wherein the first and third ultrasonic beams are focused ultrasonic beams having focus points F, and the second ultrasonic beam is an ultrasonic beam formed by a plane wave. The processor produces an ultrasonic image comprised of a first ultrasonic image for the first region A1, a second ultrasonic image for the second region A2, and a third ultrasonic image for the third region A3 based on first, second, and third echo signals obtained from said first, second, and third regions A1, A2, A3.
