Improved sensitivity and specificity of mammograms by producing uniform luminance from viewboxes

RADIOLOGISTS routinely are required to view radiographs to identify the presence or absence of disease or other malady. After careful exposure from a uniform x-ray source and careful processing, the most common way of viewing a radiograph is to place it on a viewbox. Viewboxes, however, are constructed rather inexpensively using fluorescent bulbs, reflectors and diffusers to spread the light over an area the size of an x-ray. Simple...
