【摘要】 随着可视化技术的不断发展,现代医学已经越来越离不开医学影像的信息处理,通过图像图形技术,使得医务工作者可以从多方位多层次的观察角度对影像数据进行详细的观察,可以辅助医生对病变体及其他感兴趣的区域进行定性直至准确的定量分析,而且可以大大提高临床诊断的准确性和正确性。图像处理技术引入眼科已近10年,其应用也日趋广泛,眼底图像的计算机分析系统的建立,可以对眼底许多组织进行定量测量,在正常和异常之间提供鉴别帮助,使眼底系统形态的研究向标准化和功能分析进展,从而大大加强眼底检查优势。课题针对视网膜图像的特点和眼科的实际需求,从软件开发设计的角度,根据RIS系统(Radiology Information System)的开发规范。一方面用VC++编程工具针对性的选取一些图像处理方法完成视网膜图像处理系统模块;另一方面建立眼科在线网站系统,提供无纸化医疗过程,实现数字化管理。与此同时,将病人的视网膜图像和信息存储在数据库中,便于管理。在视网膜图像处理系统模块将视网膜图像处理方法分为图像增强、图像几何变换、图像分割、图像配准与拼接、血管管径测量、彩色图像处理等。这些处理方法能够较为全面的给医生提供分析工具,帮助医生更好的分析患者病情并做出诊断。在眼科在线网站系统中,实现了无纸化管理,能够通过网站系统登记患者的档案,对患者档案、患者图像、留言等进行管理。系统具有较好的再开发性和可拓展性,使用方便。更多还原

【Abstract】 Along with the technology of Visualization development, the modern medicine already more and more could not leave the medicine phantom the information processing, through the image graph technology, causes the medical worker to be possible to carry on the detailed observation from the multi-positions multi-level observation angle to the phantom data, may assist doctor and other is interested to sickness anomalous form the region qualitatively to carry on until the accurate quantitative analysis, moreover may enhance the clinical diagnosis greatly accuracy. Imagery processing technology introduction ophthalmology department already nearly 10 years, its application also widespread, the eyeground image computer analysis system establishment, may carry on the quantitative measurement to eyeground many organizations, normal and exceptionally provides the distinction help, causes the eyeground system shape the research progresses to the standardization and the functional analysis, thus strengthens the eyeground inspection superiority greatly.Topic in retina image characteristic and ophthalmology department’s actual demanded, from software development design angle, according to RIS system development standard. On the one hand, programs pointed selection some imagery processing methods with VC++ to complete the retina imagery processing system module; On the other hand, establishment ophthalmology department on-line website system, provides Scripless the medical procedure, the realization digitization management. At the same time, patient’s retina image and the information storage in the database, is advantageous for the management. Dividing into the retina imagery processing system, the retina imagery processing method includes enhancement, geometry transformation, division, matching and mosaic, the blood vessel caliber survey, color image processing and so on.. These processing methods can comprehensive provide to doctor analyze tool, help doctor the better analysis patient condition and make the diagnosis.The ophthalmology on-line website system, has realized scripless management, can register patient’s docments, the patient’s images, the message and so on. The system has good the development, easy operate.更多还原
