| 中文摘要: |
| 窗口灰阶处理是一种具有重要意义的图象变换方法。使用者可以根据需要设计不同的变换曲线,以得到所希望的变换效果。本文通过设计不同的变换曲线,对照它们对B超图象产生的变换效果阐明了窗口灰阶处理的原理和方法。在临床应用中,本文选择了几种肝癌及囊肿的B超图象进行了窗口灰阶变换。从变换的结果可看到,原来并不明显的实性病灶经过变换清晰地显示了出来,且可抑制液性暗区内的伪像。 |
| 英文摘要: |
| The grey level processing in a sampling window is a very important method for image transforming.The users can freely design different kids of transform curves for they own purposes to obtain a perfect transformed result.In this paper the principle and method of gray level processing in a sampling window are explained with some of B scan images transformed by designing different grey level processing curves.In clinic applications some B scan images of liver cancer and cyst are selected to operated this kind of processing.The results show that a confuse real focus of infect can be distinctly seen and the virtual images in liquid dard region can be also restrained after the transforming. |
