Abstract
An improved radiological device comprising a grid cabinet and an X-ray cassette tray, including: means for cassette size sensing disposed in the cabinet and allowing for automatic collimation of an X-ray beam by a direct mechanical linkage of sensing components with shutter controls; means for centering a cassette including two pivotal arms pivoting about respective points positioned in two different places on the tray; ball rolling slides for all linear movements; means for actuating a grid frame being very compact and disposed in the back of the cabinet and, firstly, accelerating the grid substantially instantaneously to high speeds for very short exposure times; secondly, slowing the grid down for medium exposure times; and thirdly, reversing the grid travel direction at random points.
