Problems solved by technology

If it is detected by the Doppler method, the velocity also becomes random, so even if only the fundamental wave component is used, for example, the velocity from the tissue cannot be correctly estimated
[0007] (2) Harmonic TDI (Harmonic Tissue Doppler Imaging), which is difficult to be affected by stationary noise and improves the speed estimation accuracy, cannot be used
On the other hand, since the organization is ignored, the information from the organization cannot be used for tracking, etc.

Embodiment 1

[0021] FIG. 1 is a block diagram showing the configuration of main parts of an ultrasonic diagnostic apparatus according to Embodiment 1. As shown in FIG.

[0022] As shown in Fig. 1, the ultrasonic diagnostic apparatus has an ultrasonic probe 1, a transmitting system circuit 2, a receiving system circuit 3, a B mode processing circuit 4, a CFM mode processing circuit 5, a TDI mode processing circuit 6, a PWD mode processing circuit 7, a digital A scan converter (DSC) 8 , an image memory 9 , a display 10 , a body signal input section 11 and a controller 12 .

[0023] The ultrasonic probe 1 includes an array-type piezoelectric vibrator arranged at its front end. In the array vibrator, a plurality of piezoelectric elements are arranged linearly, and the direction in which they are arranged is used as a scanning direction, and each of the plurality of piezoelectric elements forms channels for transmission and reception. Therefore, the ultrasonic probe 1 can bidirectionally perfo...

Abstract

The ultrasonic diagnosis device of the invention is characterized in that the device includes the following components: an ultrasonic detector which transmits and receives the ultrasonic; a controller which drives the ultrasonic detector to time-sharing transmit the first ultrasonic that is used for executing imaging to the contrast medium putted to the inner side of the detected body and the second ultrasonic that is used for detecting the tissue moving information of the detected body. Besides another sample is characterized in that the device comprises the following components: a device which drives the ultrasonic detector to time-sharing transmit the first ultrasonic and the second ultrasonic that comprises the acoustic pressure hardly breaking the contrast medium at the inner side of the detected body and is used for detecting Doppler displacement; a device which uses the signal generated by the first ultrasonic in the contrast medium to obtain the bloodstream information; and a device which uses the signal generated by the second ultrasonic to obtain the movement information of tissue.

Description

technical field [0001] The invention relates to an ultrasonic diagnostic device and an ultrasonic diagnostic method for obtaining blood flow information and tissue motion information by using ultrasonic waves. Background technique [0002] Quantitative evaluation of local motion (systolic and dilated functions) such as the heart is very important for understanding the function. For example, it has been known that in the case of ischemic heart disease and the like, local wall motion changes occur due to insufficient blood flow supplied from coronary arteries. Several methods, such as a tissue Doppler method and a B-mode luminance tracking method, have been proposed as quantitative evaluation methods for these local wall motions. [0003] On the other hand, in recent years, a method of administering an ultrasound contrast medium to grasp the perfusion state of the blood flow to the myocardium and imaging the blood flow in the myocardium by utilizing the strong ultrasound scat...
