HIFU设备中肿瘤定位及其轮廓提取和记录

The research on the tumor’s position and the extract and record in HIFU

建立了基于一个个B超切片图像构成的三维重构肿瘤定位方法的模型,采用频域法对B超切片进行了清晰化处理,且用直线逼近法对处理后的切片图像肿瘤轮廓进行了提取和记录. 研究表明:用频域法对切片图像进行清晰化处理的方法是正确的且可行的;用直线逼近法所获得的肿瘤轮廓与实际病灶轮廓基本吻合.

The modeling of three-dimensional recombinant orientation technique is based on lots of section profiles gained by type-B ultrasonic, but these profiles doesn’t have high differentiate, so after the analysis of some clear treatment techniques, this text adopt frequency domain method to make the section profiles clear, then extract and record the worked profiles using line-approaching method. The study shows that: 1. Frequency domain method is right and approved. 2.The tumor figures gained by line-approaching method and the real focus coincide in the main.
