Abstract

The invention is suitable for the technical field of ultrasonic imaging and provides a method and a corresponding device for pseudo-color conversion of an all-digital ultrasonic image. In the embodiment of the invention, a pseudo-color mapping table is generated, the imported pseudo-color mapping table is received through an import interface and black and white image data can be converted into pseudo-color image data by a table lookup method so as to more flexibly load various gray scale mapping curves comprising linear mapping curves and also load nonlinear mapping curves to make pseudo-color effect richer. When the pseudo-color mapping table is generated, a black and white image is processed by image processing software so as to achieve the target pseudo-color effect and the corresponding pseudo-color mapping table is calculated according to the target pseudo-color effect. For example, the pseudo-color mapping table can be generated by utilizing combined treatment of Photoshop software and matlab software, so that the pseudo-color mapping table is generated and better pseudo-color effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic imaging, and in particular relates to a method and a corresponding device for pseudo-color transformation of an all-digital ultrasonic image. Background technique [0002] In the black-and-white B-ultrasound instrument, the use of image pseudo-color transformation technology can improve the ability of image discrimination. The principle of pseudo-color transformation is to transform each different gray level of the grayscale image into different color codes according to the mapping function, so that the image is displayed in color, and the image is clearly layered and easy to identify. According to the principle of chromaticity, any color can be synthesized by the three primary colors of red, green, and blue in different proportions. Therefore, the pseudo-color processing of the image must first set the functional relationship of the three primary colors of red, green, and blue. Make each corr...
