Industrial CT Truncated Projection Data Reconstruction System Based on Artificial Intelligence

In industry, Computer Tomography (CT) is a key technology used for non-destructive testing and evaluation of internal structures, but significant challenges remain in the processing of truncated projection data. The aim of this study is to investigate an artificial intelligence-based reconstruction system for industrial CT truncated projection data. We investigate the common data truncation problem in industrial CT technology and propose a new data reconstruction method. The method uses the ideas of full variance minimization and segmentation constants to achieve accurate reconstruction of truncated projection data by means of parallel computation. Our study validates the effectiveness and superiority of the method through comparative experiments. Compared with conventional methods, our system excels in both accuracy and stability of reconstruction results, and is better able to handle the challenges posed by truncated data. In addition, we explore the practical application value of the system, demonstrating its potential use in industrial CT. From a single-core to a dual-core processor, the processing time is reduced from 120 to 60 seconds, showing a doubling of the processing speed, which indicates that tasks are efficiently distributed and executed among multiple cores. The research results in this paper will have a positive impact on the development and application of industrial CT technology and promote its wide application in industrial production and quality control.
