ABSTRACT:
In radiology X-radiation from, an X-ray tube is directed toward a patient and received by an image means, which may be a film, to produce a visual image. The X-ray may be intended to detect a particular feature or area; however, the picture may be obscured by the unequal X-ray attenuation effect of the patient. That adverse effect is minimized by an attenuation mask which equalizes attenuation across the entire field. An individual mask is formed for each patient, on an almost real-time basis, by a first X-ray exposure which is analyzed to determine the extent and location of the patient's attenuation. The mask is produced, based upon that analysis, providing different attenuation at different areas, by depositing ink jet droplets, having suitable metal material, on an absorbent substrate.
