Abstract

The method involves exposing the body of a patient (P) to an X-ray, and obtaining an initial image (10) representative of an internal structure of the body through an image detector (3). The initial image is corrected using a deconvolution filter (18) for obtaining a final image. The filter has a limited size and is at local action in the initial image, where the action depends on local dosage of radiation in the initial image.
