摘　　要：提出了基于现代数字信号处理器(DSP)技术进行CT重建软件设计。在实际的CT软件设计过程中,利用TI的C6701 DSP芯片的硬件处理系统,建立了基于DSP硬件系统的CT算法重建软件,该软件全部使用与DSP硬件系统相关的DSP汇编语言进行编程。并利用TI的C6701 EVM开发板,通过输入CT数据进行计算,得出的CT图像满足实际要求。The convolution back project （CBP） algorithm is used to realize the CT image＇s reconstruction in ICT generally, which is finished by using PC or workstation. In order to add the ability of multi-platform operation of CT reconstruction software, a CT reconstruction method based on modern digital signal processor （DSP） technique is proposed and realized in this paper. The hardware system based on TI＇s C6701 DSP processor is selected to support the CT software construction. The CT reconstruction software is compiled only using assembly language related to the DSP hardware. The CT software can be run on TI＇s C6701 EVM board by inputting the CT data, and can get the CT Images that satisfy the real demands.
