Description

One important parameter to be measured when acceptance or routine testing the Mammographic X-ray set is the effective focal-spot size. Care must be exercised when conducting such measurements to ensure the correct alignment of the object and image planes to the reference axis of the X-ray tube. The test jig described enables the necessary alignment to be obtained easily and accurately. (author)
