基于个人电脑的肝脏CT灌注软件开发

Development of hepatic CT perfusion software on personal computer

目的 开发能够运行在个人电脑上的肝脏CT灌注软件 ,计算肝脏动脉、门脉灌注参数 ,并绘制相应的伪彩色灌注图。方法 在个人电脑上 ,使用Delphi 7 0软件开发平台开发包括医学数字成像和通信标准 (DICOM)文件读取、存储、显示接口的平台 ,在该平台之上开发肝脏灌注后处理软件PerfX。结果 PerfX基于Windows2 0 0 0 /XP操作系统 ,能够在CPU 5 0 0MHz以上 ,内存 12 8M以上的个人电脑上流畅地运行 ,可以测量特定感兴趣区的动脉、门脉灌注和肝灌注指数 ,并可以绘制相应的伪彩色灌注图 ,在 1幅图像中显示肝脏解剖和功能的结合图像。结论 PerfX在个人电脑上实现了从DICOM文件底层处理到肝脏CT灌注算法和灌注图绘制的后处理过程。

Objective To develop hepatic CT perfusion software on personal computer (PC), and to calculate hepatic perfusion parameters and render pseudo color perfusion image Methods A DICOM supported platform was developed on PC with Delphi 7 0, including DICOM data reading, storage, and display interfaces Hepatic CT perfusion software (PerfX) was developed upon this platform Results This software was based on Windows 2000/XP system, which could run smoothly on a computer with CPU above 500 MHz and RAM above 128 MB It could calculate hepatic arterial perfusion, portal venous perfusion, and hepatic perfusion index of region of interest, and show anatomic and functional details within one pseudo color perfusion image Conclusion A complete post processing was finished on PC by using PerfX, from DICOM data support to arithmetic analysis
