虚拟仿真教学在《医学影像设备学》教学中的研究与应用

Researching and Application of Virtual Simulation Teaching in Medical Imaging Equipment Teaching

目的:为了克服医学影像设备在教学中存在的原理抽象、教学成本高等种种限制,提出开发医学影像设备虚拟仿真教学系统的方案。方法:以万东程控X线机为例,以Visual Basic 6.0和Keil C51为开发平台,在PC机上模拟操作台的功能,利用下位机系统完成旋转阳极启动、灯丝预热和曝光过程。结果:该系统通过形象生动的操作画面,真实地模拟了程控X线机的工作原理和操作过程,使理论授课和实验教学达到完美融合。结论:对于其它医学仪器的虚拟设计,该方案具有重要的参考价值。

Objective： In order to solve Medical Devices＇ disadvantages of abstract mechanism and high cost, the paper offered a virtual teaching system of Medical Devices. Methods： Taking WANGDAONG programmable X-ray machine as example and Visual Basic 6.0 and Keil C51 as development platforms, the virtual operator is designed by using Personal Computer ,and the rotating anode＇s starting and delay, warming-up and exposure are stimulated in lower computer system. Results： By offering vivid operation images, the system stimulates the working principle and operation process of programmable X-ray machine, and achieves the perfect fusion of theoretical and experimental teaching. Conclusions： This scheme can be applied to other kinds of medical instruments.
