The developmental history of B-ultrasound

Time : 2023-02-16

B- mode ultrasound is an emerging discipline that has developed rapidly in recent years, and it has become an indispensable diagnostic method in modern clinical medicine.


B-ultrasound goes through a development process from two-dimensional B-ultrasound, three-dimensional B-ultrasound, four-dimensional B-ultrasound, the common B-ultrasound and color B-ultrasound are both two-dimensional planar images.

The common B-ultrasound uses black-and-white ultrasound diagnostic technology, in which the image measured by the ultrasound probe is black and white, and only can observe the fetal tissue structure, measuring how large and of how long the head is. Thereby color B-ultrasound comes of age. Color B ultrasound the observed image is dominated by red blue two color, with the probe facing presentation in red and vice versa in blue. It can show the distribution of the color image of the dynamic Doppler flow within the heart, whether in the resolution and clarity of the image, or the reliability of the disease diagnosis, while displaying the dynamic heart black and white image, which is relatively intuitively accurate.

Four dimensional color ultrasound

With the development of computer technology, three-dimensional B-ultrasound has emerged. It can visualize and stereo visualize the three-dimensional structure of human organs and observe it dynamically and in real time, whereas previous two-dimensional imaging techniques can only show a certain section of a human organ. 3D B-ultrasound provided richer imaging information for clinical ultrasound diagnosis, reduced the missed lesions and improved the diagnosis and treatment quality.

Four dimensional ultrasound, is currently the most advanced color ultrasound equipment in the world. The fourth dimension refers to this vector in time. For sonography, 4D ultrasound technology is a recently developed technique, and 4-dimensional ultrasound technology is to employ 3-dimensional ultrasound images plus temporal dimension parameters. This technology enables the acquisition of three-dimensional images in real time, surpassing the limitations of conventional ultrasound. It offers multifaceted applications in a number of areas including abdomen, blood vessels, small organs, obstetrics, gynecology, Urology, neonatology, and pediatrics.
