A method of CT scanning a plurality of aerofoil blades that includes providing a rotatable support arranged for rotation about an axis of rotation and within an energy beam; mounting a plurality of aerofoil blades to the support in spaced-apart relationship to one another to form at least one array around the axis of rotation; and rotating the support about the axis within the beam. Each blade has an aerofoil section and is mounted to the support. The method also provides an elongate identification element on the rotatable support, the identification element being arranged such that its longitudinal axis is parallel to the axis of rotation and having a transverse cross-sectional shape along at least part of its. Each edge feature corresponds to and is directed towards a respective said blade to thereby facilitate identification of individual the blades in a CT output obtained via the method.
