Paper Abstract

I must assume that all of us here are fully aware that the prevailing practice with manufacturers of x-ray tubes is to mislabel their products. Similarly, I am sure that all or most of us here know that appallingly few radiologists have been aware of this practice of mislabeling of x-ray tubes with regard to focal spot size. For many years I was one of the vast majority of radiologists who believed what I read on the label. I accepted the label designation "1.0-2.0" or "0.3" as a mathe-matically accurate description of focal spot size of the x-ray tube to which the label was affixed. Some 4 years ago I discovered otherwise. For the past three years I have been probing the boundaries of the practical consequences of this mis-labeling. Important facets of mislabeling include the clinical side effects: The important need for informing the profession, and, inevitably, the process of redress necessary to attain accurate or real world labeling of x-ray tubes.
