Abstract
For the software used in 3-D X-ray CT such as dental CT or micro CT, it is desirable to integrate conebeam tomographic image reconstruction, volume visualization, and image measurement, but such integrated software is currently rare and expensive. As described in this report, by implementing several previously known or newly developed image processing algorithms using a GPU, we have developed software called TomoShop which integrates all of the above-mentioned functions. Furthermore, based on evaluation of its application to dental CT imaging, we have implemented specific image processing algorithms for panoramic display, nerve extraction, and distance measurement. Consequently, we have achieved the main goal of integrating the above-mentioned functions into a single software package and have realized high speed, high image quality, and high generality by adopting GPU implementation and scientifically novel image reconstruction, compensation, and processing algorithms. We have confirmed the high performance of this software by conducting various experimental studies and look forward to making it available to CT manufacturers at a reasonable price.
