随着图像处理及超声技术的进步,各种图像处理方法不断应用于超声领域.本文主要介绍电子扇形B超诊断仪中的数字图像前处理技术,其中包括二次采样、采样处理、平滑处理、帧相关处理和边缘检测等.进行这些处理的目的是为了去除噪音改善图像质量,使模糊的图像变清晰,突出轮廓或扩大细微差别,即根据医生的要求突出某一部分的信息以有助于医生的诊断.
With the advancement of image processing and ultrasonic technology, various image processing methods are continuously applied in the field of ultrasound.This paper mainly introduces digital image preprocessing technology in electronic sector B ultrasonic diagnostic apparatus, which includes sub-sampling, sampling, smoothing, Frame correlation and edge detection, etc. The purpose of these processes is to remove noise to improve the quality of the image, to make the blurred image sharp, to emphasize the outline or to expand the nuance, that is to highlight a certain part of the information according to the doctor’s request to help the doctor Diagnosis.
