    Abstract: A rollable structure for suspending a heavy radiation protective garment so as to allow easy movement in a clinical environment subject to exposure to x-radiation. The structure comprises a vertically extending frame that is attachable to a user, and that permits the user to move freely around the clinical environment and to perform clinical duties without having to bear the weight of the shielding garment. The frame is vertically adjustable, and supports upper shield support surfaces for supporting the shoulder portions of a radiation protection apron. The upper support surfaces extend outwardly from the vertical frame. A rollable lower support frame for the vertical support frame is provided that includes a first lower frame extending forwardly from the vertically extending frame. A second lower frame for supporting the vertically extending frame is located at a position other than forwardly of the vertically extending frame.

    Abstract: A mu3li-ply, preferably flexible, x-ray shielding material which can be formed into a garment is provided. Such material is lighter in weight but that provides a specific degree of protection under the standard conditions met in fluoroscopy by workers in the field subjected to reflected, or scattered, radiation emanating from the patient's body. The multi-layered fabric is so constructed that the amount of re-radiated energy, or fluorescence produced by each layer, is greatly attenuated. Generally, this invention is directed to a material formed of two or more layers of a polymeric or clastomeric film or sheet loaded with different radiation-attenuating metal material,

    Abstract: An x-ray tube and method of operating include a vacuum chamber vessel and a source of an electron beam inside the vacuum chamber vessel. A target disposed inside the vacuum chamber vessel includes a substrate and one or more deposits attached to the substrate. Each different deposit includes an atomic element having a different atomic number. The x-ray tube also includes a means for directing the electron beam to a selectable deposit of multiple deposits. The substrate material can be selected with better vacuum sustaining strength, x-ray transparency, melting point, and thermal conductivity than a deposit. The substrate may be cooled by an integrated cooling system. The x-ray tube allows a selectable x-ray frequency to be produced with enhanced economy of power, reduced moving parts, and reduced size. For improved bone mass applications, one of the deposits has a k-fluorescence energy less than about 53 thousand electron volts.

    Abstract: Techniques for deriving bone properties from images generated by a dual-energy x-ray absorptiometry apparatus include receiving first image data having pixels indicating bone mineral density projected at a first angle of a plurality of projection angles. Second image data and third image data are also received. The second image data indicates bone mineral density projected at a different second angle. The third image data indicates bone mineral density projected at a third angle. The third angle is different from the first angle and the second angle. Principal moments of inertia for a bone in the subject are computed based on the first image data, the second image data and the third image data. The techniques allow high-precision, high-resolution dual-energy x-ray attenuation images to be used for computing principal moments of inertia and strength moduli of individual bones, plus risk of injury and changes in risk of injury to a patient.
