Quick Realization of Image Reconstruction Arithmetic

摘要

Industrial Computed Tomography (ICT) technology is key detect technology for national defense, aviation and other industrial products manufacture. Owing to a large of reconstruction calculation, reconstruction time is always one of the key problems. In order to implement real time reconstruction and real time processing of the Convolution Back Projection method (CBP), the paper presented the ways of software optimization on the basis of TI(Texas Instruments) DSPs (Digital Signal Processors)hardware resources of high performance. Through CT image reconstruction processing instance, it indicated that DSPs used as calculating core can implement real time reconstruction and real time processing of CT image, and optimized DSP code of high performance can improve performance price ratio greatly. Universal PC could not implement real time CT reconstruction and processing, real time image processing technology on the base of DSPs is the developing direction in the further.
