Abstract: A test stand for use in testing the performance of an X-ray system constructed and arranged to project an X-ray beam along a defined path. The stand includes a vertical base, a first support extending horizontally from one end of the base for positioning a first test object at a first location relative to the path and a second support extending horizontally from the other end of the base for positioning a second test object at a second position relative to said path and spaced from said first test object. Each support includes a test object receiver and one of the receivers is adjustable in a direction perpendicular to the path. A leveler is mounted on the stand for leveling the first and second supports relative to the horizontal. Each of the supports is pivotally mounted on the base and holding members are coupled to the base and the supports for holding each of said supports in a horizontal orientation, the holding members being releasable to permit the supports to be pivoted toward the frame for storage.
