Ultrasonic image optimization method and system

Abstract

The invention provides an ultrasonic image optimization method. The ultrasonic image optimization method is mainly characterized by comprising the steps of obtaining an image signal, analyzing the image signal to obtain R, G and B data signals and generating gray images corresponding to the R, G and B data signals; and after calculation of an error diffusion algorithm and color quantitative processing on each of the gray images, generating image data for reducing a bit number of the image signal. The invention further provides an ultrasonic image optimization system applying the method. According to the ultrasonic image optimization method and system, the signal bit number of an ultrasonic image can be reduced so as to adapt to a display requirement of a display, the distortion of image processing is small and the ultrasonic image with excellent quality is obtained.

Description

technical field [0001] The invention relates to an ultrasonic imaging system and belongs to the field of medical ultrasonic image processing. Background technique [0002] In recent years, ultrasound imaging systems are developing toward digitization, miniaturization, multi-function, and high reliability. Therefore, portable B-ultrasound has become an increasingly popular development direction. The portable system is compact in design and complex in system. It not only needs to support continuous wave Doppler, meet the requirements of many connection functions and powerful processing capabilities, but also needs to provide excellent resolution to facilitate doctors' diagnosis. [0003] Most of the colored lights common in nature can be simulated by the equivalent colors of the three basic color combinations in appropriate proportions. This equivalent color is similar to the color vision caused by color to the human eye. The three primary colors commonly used are red (R), ...

Problems solved by technology

[0004] In the field of digital image processing, the width of the input signal required by different types and types of display devices is generally 8 bits and 6 bits, while the width of the ultrasonic echo after passing through the ultrasonic imaging system has reached 10 bits, 12 bits, Even 16-bit, etc., when the ultrasonic imaging system is used for an 8-bit or 6-bit display, it is necessary to process the width of the signal to meet the requirements of the display, so that the signal can be displayed on the screen normally. In the past digital image processing process Generally, the method of directly discarding the low bits is used to meet the requirements of the input signal width of the display device, and the resulting signal distortion is also obvious, and the image quality is not satisfactory, which will directly affect the diagnosis of the imaging doctor.
