We developed a complete GPU based data processing for cone-beam micro CT application which performs not only the reconstruction but also all the correction of the projection images on-the-fly. Test measurements were performed and processing times was compared on different hardware setups. The performance of the GPU together with our modified algorithm allow to process all the calculations within the shortest exposure time of the system for the highest reconstructed volume size thus makes possible the complete data processing in real-time.
