虚拟仿真教学在《医学影像设备学》教学中的研究与应用

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VisualBasic6．0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。

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

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.
