通过对我国医院现有医学影象系统的分析与研究,针对其存在的问题,提出并实现了一种医学影象处理系统,以PC总线标准为平台,采用局部总线与高速视频总线相结合的设计技术,完成了高速机器视觉采集卡的设计.数据率达10兆字节/秒,可实时将来自医学影象系统的动态图象摄入计算机。图象处理软件功能设置上充分考虑了医学影象的特殊性,可提取病变区域,进行几何变换、边缘提取、形态参数计算、增强处理及伪彩色变换等,从根本上改变了医学影象的视觉效果,为医生诊断提供了定性定量数据;实现了影象和病历的计算机数字存贮、管理与检索。
Through the analysis and research of the existing medical imaging system in our hospital, aiming at its existing problems, a medical image processing system is proposed and implemented. Based on the PC bus standard, a local bus and a high-speed video bus are used Design technology, completed the design of high-speed machine vision acquisition card. Data rates up to 10 megabytes per second enable real-time imaging of dynamic images from medical imaging systems into computers. The function of the image processing software fully considers the particularity of the medical image, extracts the area of the lesion, performs the geometric transformation, the edge extraction, the morphological parameter calculation, the enhancement processing and the pseudo color transformation, and fundamentally changes the medical image Visual effects, provide qualitative and quantitative data for the diagnosis of the doctor; to achieve the computer digital storage of images and medical records, management and retrieval.
