This paper presents the evaluation of an image quality measure for X-ray computed tomography (XCT) scans. This quality measure can aid XCT users in selecting scans with optimised quality, which finally objectify their selection. The proposed measure is calculated on the base of a grey value histogram which leads to a global quality criterion that is able to rate scans of single- as well as multi-material objects. Several micro-XCT scans of different specimens with varying image quality are used to verify the proposed image quality measure.
