Collimation of X-ray Diagnostic Bundle by Means of Steering Ferrofluid

Abstract

An extruded three-phase base pan for a load center has a central rail with a cross-sectional configuration in the form of a modified cross. The upper surface of each arm of the cross curves upward and away from the body of the cross. The bottom surface and top surface of each arm are joined by a U-shaped surface. The bottom of the base pan has ribs with integrally formed grooves.
