METHOD, APPARATUS AND PHANTOM FOR MEASURING AND CORRECTING TOMOGRAM ERRORS
摘要
A tomogram taken on an imaging path of a tomograph is corrected by using sets of tomogram correction data for neighbouring positions on that path, in an interpolative process. An error map of a tomograph is built up by comparing tomograms of a phantom with the expected appearance of the phantom at the tomogram positions. Also provided is a phantom having a body with one or more imaging fluid receptacles formed therein
