Fluoroscopic image filtering method, involves correcting initial image using deconvolution filter that has limited size and is at local action in initial image, where action depends on local dosage of radiation in initial image

摘要

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.
