基于CSCW实现医学影像处理与阅片教学的信息化

Medicinal Image Processing and Reading Teaching Informatization based on the CSCW Mode

医学数字影像的操作与处理对今后从事放射和影像诊断工作的医科学生来说是重要的学习内容。传统的影像操作教学模式不能实现师生互动和课堂教学的信息化。本文在详细分析了CSCW影像处理教学系统的组成、特点与功能后,指出了CSCW模式能有效地整合医学数字影像的操作与师生完成在线协同式教学的过程。实现方法采用软件设计,分为阅片模块与通讯模块。阅片模块采用面向对象方法,通过网络指令进行的影像操作。通讯模块包括资料传输、指令传输和信息传输,基于Client/Sever的网络模型是建立在TCP/IP基础上。达到了同一影像对象教学方与学习方之间同步处理、实时交互的效果;实现了医学图像的编辑或修改过程既能使操作者看到,同时让所有参与者都能感受到此变化的操作结果共享;并且群体成员利用影像操作模块和授权的电子白板,构成了多方参与操作和讨论的网络平台。从而实现了利用信息技术化工具的教学,帮助学生深入理解医学数字影像操作与处理的方法、提高解决问题和创新思维的能力,真正达到了教学的信息化和互动教学的效果。

Processing and reading of Digital Imaging in Medicine are very important matters for the medical students who are going to work in the fields of radiation and imaging diagnose. The traditional teaching method of operating imaging can＇t realize the interaction between teachers and students, at the same time the informationization of class teaching can＇t be carfled out. In this article, the authors analyses the composition, characteristics and function of CSCW imaging teaching system, in this way the authors point out the CSCW method can effectively conform the handling of digital imaging in medicine and the cooperation of teachers and students on line. The methods of realizing it have two, one is reading module, and the other is communicating module. The former one applies to the method of object-oriented, using internet instruction operates finages. The communicating module includes data transmission, instruction transmission and information transmission. The network models which are based on C/S are developed at the basis of TCP/IP. Realizing synchronization and interaction in teaching and studying when the same image reaches, also the process of editing and modifying medicinal images are not on- ly be seen by operator, but also be shared by all the people who join in. At the same time, with the imaging operating module and the authorized electronic whiteboard, all the members join in consist of the multi-side participation and discussion net platform. Consequently, the teaching system which combines the usage of informatization has been completed, helping students have better understanding of operation digital imaging in medicine and improve the ability of dealing problems and creative thinking, in this way to make the interaction and informatization of teaching come true.
