  • Page 37: Chapter 3 Theory Of Operation

    Chapter 3 Theory of Operation OVERVIEW The Model QS-550 Tubestand is a free-standing x-ray tube support device (i.e., does not require wall and/or ceiling mounting) that provides a wide range of tube positions through longitudinal, vertical, rotational, and transverse tubestand motions. The Handgrip Assembly is designed for operator convenience with ergonomically posi- tioned push button switches that enable tubestand movement when pressed.
