Ludlum Medical Physics Model L-644
Grid Alignment Test Kit
Introduction
The Ludlum Model L-644 Grid Alignment Test Kit is
designed to confirm that the proper centering, and height uniformity of a
standard or focused grid is correctly aligned with the central axis of the
x-ray beam.
The test procedure is simple and requires that the holed test plate is
centered to the
x-ray table and positioned such that the length of the
tool is perpendicular to the direction of the grid lines. One exposure is
then made centered over each hole in the test plate. After processing, the
film (image) is examined for potential changes in optical density. A
properly centered and level grid should provide 5 equal densities on the
test film (image).
The test kit includes one holed test plate, 9” x 3.5”, with 5 test holes.
There are also 2 blocking plates which are 3.5” x 2.375”. The three plates
are made up of 0.0625” thick lead encased in acrylic material for ease of
handling.
