A method for validating computed tomography (CT) techniques and individual inspections is provided with a CT reconstruction algorithm, an x-ray source, a primary rotational stage, a secondary rotational stage, and an x-ray beam detector. A test object is situated on the primary rotational stage and a plurality of image quality indicators (IQIs) is situated on the secondary rotational stage. The x-ray source, the primary rotational stage, the secondary rotational stage, and the x-ray beam detector are linearly aligned. Therefore, an x-ray beam from the x-ray source intersects the test object and the IQIs before reaching the x-ray beam detector. A CT reconstruction is developed by superimposing a plurality of projection data from the test object and the IQIs. More specifically, a CT reconstruction from the IQIs with a specific intensity value is added to the CT reconstruction of the test object.
