Abstract
In recent years, CT technology has become increasingly mature. However, the existing CT imaging methods still have great difficulties in large object imaging, high resolution imaging and radiation dose reduction. In fact, many engineering applications do not require global CT imaging of a complete object, only the object images of some regions of interest can be obtained, especially in clinical medical diagnosis, as long as the image of suspicious lesions can be achieved. The theory of CT image reconstruction is the basis of medical imaging technology. In order to help medical imaging students better understand the idea of CT image reconstruction, this paper studies the method of CT image reconstruction for regions of interest. Three kinds of image reconstruction methods for projection data under different truncation modes are introduced. The corresponding numerical simulation experiments are designed and the numerical simulation results are given. Finally, the potential application of CT imaging technology in engineering is prospected.
