摘 要：B超圖像作為醫(yī)學(xué)圖像的一個(gè)部分，具有醫(yī)學(xué)數(shù)字圖像的某些共性。B超圖像處理技術(shù)作為醫(yī)學(xué)數(shù)字圖像處理技術(shù)的一個(gè)分支，其研究內(nèi)容包括很多方面，主要有：B超圖像的增強(qiáng)、B超圖像的濾波、B超圖像分割及邊緣輪廓提取等。本文提出了基于Visual C++在圖形圖像處理方面具有得天獨(dú)厚的優(yōu)勢，利用Visual C++編譯的程序進(jìn)行對(duì)圖像的快速處理，灰度線性變化；圖像增強(qiáng)：圖像的平滑、銳化；二值化處理。使得圖像在計(jì)算機(jī)處理之后，可以最大程度的保留了影像的信息，同時(shí)優(yōu)化了分類后的影像，主要用途是獲取物體拓?fù)浜徒Y(jié)構(gòu)信息，它通過物體和結(jié)構(gòu)元素相互作用的某些運(yùn)算，得到物體更本質(zhì)的形態(tài)。以便醫(yī)生了解病變組織或器官的綜合情況,并做出更加準(zhǔn)確的診斷或制定出更加合適的治療方案,毫無疑問,這必將推動(dòng)現(xiàn)代醫(yī)學(xué)臨床技術(shù)的巨大進(jìn)步。

Abstract：The B ultra image took the medicine image a part, has medicine digital image certain general character. The B ultra imagery processing technology took the medicine digital image processing technology a branch, its research content including very many aspects, including: B ultra image enhancement、B ultra image filter、B ultra image division and edge outline extraction and so on. This article proposed has the advantageous superiority based on Visual C++ in the graph imagery processing aspect, Translation procedure carries on using Visual the C++ to image fast processing, Gradation linear variation; Image intensification: Image smooth, peaking; Filters the mirror effect: Binaryzation processing. Causes the image after computer processing, might the greatest degree retention phantom information, after simultaneously optimize the classified phantom, the main use was gains the object analysis situs and the structure information, it certain operations which affected mutually through the object and the structural element, obtained the object essence shape. In order to doctor understood the pathological change organizes or the organ comprehensive situation, and makes a more accurate diagnosis or formulates the more appropriate treatment plan, without a doubt, this will certainly to impel the modern medicine clinical technology the huge progress.
