Abstract
Computed tomography plays an important role in industrial non-destructive testing, medical applications, astronomy and many other fields to analyze inner structures of scanned objects. This article addresses a new development of non-destructive testing software platform to efficiently detect inner flaws of space industrial components. As the key of our software, reconstruction algorithms of 2D industrial computed tomography including preprocess of raw data, re-arrange algorithm and filtered back-projection algorithms have been described in detail in this article. Experimental results with four groups of real raw data from China Aerospace Science and Technology Corporation confirmed the accuracy of the reconstruction algorithm in our software. Forward algorithm of 2D industrial computed tomography is another important component of our software, which conveniently generates parallel-beam and fan-beam raw data with given parameters.
