X-刀数据输入接口软件的开发

The Development of A Interface Software for Data lnput ln X－Knife

目的：探讨一个方案，使得Leibinger-Fischer X-刀能利用Elscint CT/MRI图像数据进行立体定向放射外科计划的制定。方法：考察Elscint CT/MRI和Siemens DR3 CT文件系统及图像数据结构，利用PC机实现Elscint CT、MRI图像数据向Siemens DR3 CT图像数据的格式转换。结果：Elscint CT图像数据能正确传输到Leibinger-Fischer X-刀工作站进行立体定向放射外科计划的制定。结论：对于专门计算机系统之间的数据传输或交换，由于其软、硬件相对封闭，很难从系统程序和应用程序层面解决问题，而从它们的数据接口寻求突破，事实证明是有效的。

Objective To explore a way that enables Leibinger－Fischer X－knife workstation to accomplish planning of stereotactic radiosurgery by using Elscint CT、MRI image data． Methods The file system and data format of Elscint CT MRI and Siemens DR3 CT having been investigated，the image data of Elscint CT MRI are transformed to the same format as Siemens DR3 CT＇s．Result The image data of Elscint CT can be transferred to Leibinger－Fisher workstation and then be used to accomplish planning of stereotactic radiosurgery．Conclusion It＇s very hard to settle the problem of data transferring or exchanging among various exclusive computer systems by modifing their system software or applications due to their complexities and relatively exclusive characters．It has been proved effective to clear this problem by investigating data interface features of the exclusive computer systems．
