no. 2 approach

[0073] A second embodiment of the present invention is described below. This embodiment resides in performing imaging that enhances the visibility of a puncture needle or the like by further utilizing a rate subtraction method. Incidentally, the "velocity-time-interval subtraction method" is a technique of imaging using the difference between in-phase images (images of the same polarity). This technique is described, for example, in JP-A-8-336527.

Abstract

The invention provides an ultrasonic diagnostic equipment and the method for controlling the ultrasonic diagnostic equipment. Three ultrasonic transmissions of positive, negative and negative polarities are executed for each of a plurality of ultrasonic scan lines on the basis of a predetermined rate period. Echo signals generated due to the respective ultrasonic transmissions are received at the same rate. For each scanning line, addition of the echo signal based on the first ultrasound of positive polarity to the echo signal based on the second ultrasound of negative polarity produces a normal mode image. Also for each scanning line, addition of the echo signal based on the first ultrasound of positive polarity to the echo signal based on the third ultrasound of negative polarity produces centesis mode image data. The produced images of normal and centesis modes are displayed in a predetermined manner.

Description

technical field [0001] The present invention relates to improving the reliability and accuracy of, for example, ultrasound-guided paracentesis, and more particularly to an ultrasonic diagnostic device for improving the visibility of a puncture needle, and a method of controlling the same. Background technique [0002] An ultrasonic diagnostic device is a medical imaging device that non-invasively obtains tomographic images of living soft tissues from the surface of a body using an ultrasonic pulse echo method. Compared with other medical imaging equipment, ultrasonic diagnostic equipment has advantages such as small size, low cost, high safety without exposure to X-rays, and the ability to perform blood flow imaging. Ultrasonic diagnostic equipment is widely used in the heart, abdomen, and urinary organs, and is widely used in obstetrics and gynecology. [0003] In imaging diagnosis using ultrasonic diagnostic equipment, it is well known that by extracting the harmonic comp...
