光纤CAN网络在磁共振系统中的应用

Plastic Fiber Optic CAN Communication in MRI Equipment

文章介绍研究了一种适用于磁共振MRI系统中病床设备的光纤CAN中继方案,阐述了磁共振MRI系统的环境特殊性,光纤CAN在MRI系统中传输的适用性。通过讲解CAN双绞线传输原理和单节点到单节点光纤CAN通信原理,引入多节点光纤CAN通信拓扑的必要性,详细介绍了设计和工作原理。最后简述了该设计方案的优越性和扩展性。

The purpose of the paper is to develop one Plastic Fiber Optic CAN repeater which could be used in patient table device of MRI equipment.The paper introduces MRI equipment specifi c magnetic environment and the reason of Fiber Optic CAN communication popularity and suitability in MRI equipment.The research methods include the introduction of CAN communication principle with Shield with Foiled Twisted Paris cable and shortage of single Plastic Fiber Optic CAN node to node communication.and then states the necessity of Multi-node Plastic Fiber Optic CAN.In a result,the Multi-node CAN topography is designed and descripted with detailed block chains.In the end,the paper also indicates the expandability of the concept and design.
