A NEW METHOD OF ALIGNING A LIGHT LOCALIZER-X-RAY BEAM

EARL VAN ROOSENBEEK

Kodak linograph paper, type 1895, has been found to exhibit a response to both light and x rays in a manner which can be very useful in displaying light beam-x-ray alignment. The paper is insensitive enough to be handled in a low light level room, but self-develops under strong fluorescent light. When a sheet of the paper is attached under an x-ray portal, both the light localizer pattern and the x-ray beam can be seen without disturbing the position of the paper. Light bulb alignment can be obtained by using 1 sheet of 8 inchx8 inch paper, and by moving the bulb only once. The entire procedure can be done in about 5 minutes with greater accuracy than by previous methods.

The method can also be used to display the alignment of cross hairs and optical distance defining lights as a matter of record. The paper becomes a permanent record if placed between the pages of the machine log book and not exposed constantly to further light.
