Abstract

Computed tomography is a transmission tomography technique; this technique allows reconstructing the cross-section images or slices of the real object. The CT was developed in the 1970s for medical diagnostic purposes. Today, the CT technique has evolved to the 7th generation using cone-beam configuration (CBCT) and Flat Panel Detector (FPD) instead of fan-beam arrangement and one dimension detector array. CBCT has greater X-ray efficiency and higher spatial resolution than the previous generation; therefore, it can be used in industrial applications such as metrology of precision machined and None-Destructive Testing (NDT). In this research, the first CBCT system in Vietnam was manufactured; this system can acquire and reconstruct three dimensions of a real object with a maximum size of 200 × 300 mm within ten minutes. The resolution of the reconstructed image is around 49 µm.
