Abstract

The size of a detail of an object is derived from a data set of data values relating to the object. The data set assigns the data values to positions in a multidimensional space. A preferential direction is selected in the multidimensional space. The spatial resolution of the data set is higher in the preferential direction as compared to the spatial resolution in other directions. The size of the detail is derived from data values in the preferential direction. Preferably, the preferential direction extends along the line of intersection which intersects a scanning plane in which the data values are acquired and a transverse plane; the transverse plane extends at right angles to the longitudinal axis of the detail. The data values are acquired notably by means of an X-ray computed tomography system.
