Method for determining an image point in an object image.

摘要

A method for determining an image point in an object image comprises the steps of, on the basis of an image signal comprising image signal components representing image information at respective picture elements on a recording medium on which a radiation image including an object image has been recorded, weighting the respective picture elements with image signal values corresponding to the respective picture elements or with the reciprocals of the image signal values, thereby to find the center of gravity on the recording medium. A position, at which the center of gravity is located, is determined as the image point in the object image.
