基于电路联动的X线机模拟操作装置研究

X-ray machine simulation operation devices based on linkage circuit

针对医学影像学和医学影像技术专业学生在步入工作岗位之前对X线机操作流程不熟悉,对X线机常规维修问题知之甚少等现状,设计了一种基于电路联动的X线机模拟操作装置,该装置以低廉的成本、较高的安全性能、无电离辐射等特点解决了以下实际问题:(1)通过该实验装置使无法接触到X线机的学生熟悉X线机透视/点片或摄影操作的基本流程,熟悉在透视/点片以及摄影操作过程中各个单元电路的作用、相互联系、工作原理以及各个关键继电器的工作状态;(2)通过故障点的设计,为学生日后从事X线机维修或操作工作打下坚实的基础。

Based on the fact that students majoring in medical imaging and medical imaging technology are not familiar with the X-ray machine operation flow and maintenance before they enter the job position, a X-ray machine simulation operation devices based on linkage circuit was designed to solve the practical problems in condition of low cost, high safety performance, no ionizing radiation characteristics. Firstly, the device provided an opportunity for students who can＇t contact with X-ray machine to be familiar with the basic operation flow of radiography and fluoroscopy/spot, the function, connection and operating principle of each unit circuit, the working state of the key relay in the operation flow of radiography and fluoroscopy/spot. The design of fault points provided solid foundation for students to do the work such as X-ray machine maintenance or X-ray machine operation.
