A radiation shield is adapted to be disposed transversely across a subject supported on the surface of a procedure table to protect medical professionals working in front of the radiation shield from radiation being applied to the subject behind the radiation shield. The radiation shield includes a movable barrier positional to extend transversely across a subject supported on the surface of a procedure table. The barrier has a generally vertically-oriented lower section; a generally forwardly sloping intermediate section; and a generally vertically-oriented upper section, forwardly offset from the plane of the lower section. A side section extends outwardly and rearwardly from one side of the lower, intermediate, and upper sections of the barrier. There is a recess in the lower edge of the lower section for accommodating a portion of the body of the subject on the surface of the procedure table, with portions of the lower section on each side of the recess projecting downwardly below the surface of the procedure table. A plurality of flexible radiopaque flaps depending from the perimeter of the recess block radiation from penetrating the gap between the subject and the perimeter of the recess.

An improved medical procedure table has motorized elevation, Trendelenburg tilt, floating tabletop with both longitudinal and lateral travel, multi-caster control, and an iso-roll device for the tabletop. The iso-roll device is connected between a roll plate and a cross plate. The iso-roll device includes a pair of iso-roll guide plates, which are mounted laterally to a bottom of the roll plate. Each iso-roll guide plate has an arcuate guide channel therein having an upwards concave shape. A set of cam followers are positioned in both guide channel and travel therein and also fixedly mounted to a base on the cross plate. A center of radius of the arcuate guide channel is approximately 5 inches above the tabletop. Further, mounted between the iso-roll guide plates and to the roll plate is a support guide plate having an arcuate bottom surface.

A mobile support cart has one or more extendable and foldable arms to position one or more monitors or devices mounted to the extendable arm. The arm is mounted to a vertical column that is supported by a linear rail system providing vertical guidance. An adjustable counterweight carriage rides on a second rail set and is connected to each column through a chain and pulley. Each chain and pulley is fully redundant with two chains attached to discrete mounting points on each counterweight carriage and to each column. The amount of counterweight applied can be adjusted within a given load range by adding additional plates/ballast to the counterweight carriage. When the load on the arm(s) are fully offset by ballast on the counter weight carriage the arms and payloads reach a 'neutral buoyancy' condition. The system maintains the position once an operator has released them.

A digital, flat panel, two-dimensional x-ray detector moves reliably, safely and conveniently to a variety of positions for different x-ray protocols for a standing, sitting or recumbent patient. The system makes it practical to use the same detector for a number or protocols that otherwise may require different equipment, and takes advantage of desirable characteristics of flat panel digital detectors while alleviating the effects of less desirable characteristics such as high cost, weight and fragility of such detectors.

Apparatus and method for use in conjunction with an X-ray apparatus, for filtering scattered irradiation and enhancing recordation of unscattered irradiation transmitted through a subject exposed to an X-ray analysis beam. The apparatus includes a grid mechanism including filtration strips which filter scattered irradiation and obstruct unscattered irradiation from detection, a mechanism for recording an analog image of the subject from the detector, a mechanism for converting the analog image to an equivalent digital image, and a mechanism for reconstructing the image as if the unscattered irradiation absorbed by the grid were not obstructed from detection. The method comprises projecting a beam of X-ray photons at and through the subject to be examined, aligning an X-ray photon sensitive detector behind the subject with the beam of photons, filtering the scattered X-ray photons transmitted through the subject from detection with a grid of X-ray absorptive strips, recording an analog image of the subject from the detector, converting the analog image to an equivalent digital image, and reconstructing the image as if the unscattered photons are not obstructed or absorbed by the strips.

Anti-scatter grid system

An X-ray system has radiation carriage for an X-ray source and receptor and a table carriage for a patient. The radiation carriage moves along a circular track on a primary carriage which in turn is on a beam rotating on a standard so that a patient at the isocenter of the two circular movements can be X-rayed at adjusted angles from spherical loci. The beam also pivotally supports a table carriage so that as the patient is inclined with the table the adjusted angle of the radiation is maintained.

Spherical X-ray angulation and patient tilting system

An X-ray system includes an X-ray source directing X-radiation on a first path through a subject to an X-radiation receptor which responds to X-rays to direct light radiation on a secondary path to a light image plane. In either path or both paths is a rotating radiation-opaque mask having one or more spiral radio-transparent windows which sweep through the path as the mask rotates. Each spiral window may be formed by the overlap of coaxial spiral windows in superimposed masks which are relatively adjustable in phase to vary the window width.
