Abstract
A method for obtaining calibrated image data of a target object using a tomographic apparatus is provided. The calibrated image data is width-corrected to account for variations in the width of a collimator of the tomographic apparatus. The collimator is adjusted to one width setting when target object image data is obtained, and to another width setting when data for calibrating the target object image is obtained. The method of the present invention ensures that, notwithstanding the variation in collimator width, the target object image data is accurately calibrated.
