Transputer 在核磁共振成像系统中的应用

Application of Transputer in the Magnetic Resonance Imaging System

选择Ｔｒａｎｓｐｕｔｅｒ和ｉＲＭＸ操作系统作为核磁共振成像计算机系统基本的硬件和软件开发环境，使整个系统既有高速的计算能力，又有适应多任务环境的强大的实时控制能力．为了解决缺乏Ｍｕｌｔｉｂｕｓ宿主环境的Ｔｒａｎｓｐｕｔｅｒ开发系统的问题，设计了Ｍｕｌｔｉｂｕｓ总线接口的Ｔｒａｎｓｐｕｔｅｒ母板，并利用ＰＣ机的Ｔｒａｎｓｐｕｔｅｒ开发系统成功地开发了运行在Ｍｕｌｔｉｂｕｓ总线宿主环境中的Ｔｒａｎｓｐｕｔｅｒ图象重建软件，实际重建一幅２５６×２５６图象的时间小于２ｓ．

A magnetic resonance imaging computer system based on Transputer and iRMX operating system is introduced in this paper.The system not only has high speed computation ability,but also has powerful real time control ability adapt to multi task environment.A method of design multibus interfaced Transputer mother board is presented to solve the problem that multibus interfaced commercial Transputer development system is not available.A image reconstruction software running on the Transputer network and the multibus host environment,which reconstructs a 256×256 image in less than 2 seconds,is successfully developed through Transputer development system on the PC platform.
