Abstract: An ultrasonic diagnostic apparatus includes: an ultrasonic probe for transmitting a first ultrasonic beam BM1 to biological tissue in a subject; a transmission control section for transmitting an ultrasonic beam for generating shear waves in the biological tissue from the ultrasonic probe to the biological tissue while applying steering to the beam; and a region-defining section for defining a region in an ultrasonic image of the subject, wherein the transmission control section transmits the first ultrasonic beam while applying steering to the beam by setting transmission parameters such that the first ultrasonic beam travels closest to and outside of the region.

Abstract: To provide an ultrasonic diagnostic apparatus capable of transmitting a push pulse with conditions for transmission and a number of transmissions set suitably to a subject.

Abstract: An ultrasonic diagnostic device capable of preventing useless transmission of an ultrasonic pulse for detection from being performed characterized by including a processor that executes a program for controlling an ultrasonic probe such that transmission of an ultrasonic push pulse to a biological tissue of a test object and transmission of a plurality of ultrasonic pulses for detection on the same sound ray in order to detect a shear wave generated in the aforementioned biological tissue with the push pulse concerned are alternatively repeated, the program for controlling the aforementioned ultrasonic probe such that the aforementioned ultrasonic pulses for detection are transmitted on the aforementioned sound ray until the aforementioned shear wave is detected at a predetermined number of detection points on the sound ray that the aforementioned ultrasonic pulses for detection are transmitted.

Abstract: To improve the frame rate of an ultrasonic diagnostic apparatus for displaying an elasticity image by detecting shear waves generated by push pulses. After first and second push pulses have been simultaneously transmitted to different positions, each of a first ultrasonic detecting pulse DP1 and a second ultrasonic detecting pulse DP2 for detecting each respective shear wave generated by each of the first and second push pulses is transmitted in a different acoustic line, and in a period after the first ultrasonic detecting pulse DP1 has been transmitted and before the first ultrasonic detecting pulse DP1 is transmitted again in the same acoustic line, the second ultrasonic detecting pulse DP2 is transmitted.

Abstract: An ultrasonic diagnostic apparatus includes: a first ultrasonic probe; a first transmitting/receiving device which drives the first ultrasonic probe to perform scan with an ultrasonic beam; an ultrasonic image generating device which generates an ultrasonic image, based on a signal obtained by the first transmitting/receiving device; an image displaying device which displays the ultrasonic image thereon; a contrast timer which starts clocking in response to a start signal; a second ultrasonic probe; a second transmitting/receiving device which drives the second ultrasonic probe; and a determining device which determines based on a signal obtained by the second transmitting/receiving device whether a contrast agent has flowed in or not, and transmits the start signal to the contrast timer when the contrast agent has flowed in.
