Abstract
The spatial relation between the pixels in a medical image and their real-world position is important for clinical image display, surgery planning, image fusion and comparison of images acquired with di erent pixel sizes, orientations, scan- ners or time points. The correct manipulation of this `geometry' or `spatial referencing' can be challenging. This paper aims to provide a clear description of the link between the data in the computer, array indexing and the 3D location where the image data was acquired.
