As far as Tianjin Wanji Medical Equipment Manufacturers know, B-ultrasound displays the echo signal in the form of light point brightness (gray scale). The intensity of the light spot reflects the intensity of echo interface reflection and attenuation of ultrasound. These light points, rays, and smooth surfaces constitute a two-dimensional tomographic image or section image of the detected part, and this image is called a sonogram.
