Filed:

Nov 26, 1993

Appl. No.:

8/158625

Inventors:

Anthony J. Pellegrino - New Fairfield CT
Kenneth F. Defreitas - Patterson NY
Daniel N. Lyke - New Milford CT
Richard F. Schutz - Brewster NY

Assignee:

Lorad Corporation - Danbury CT

International Classification:

H05G 102

US Classification:

378198

Abstract:

An improved mobile X-ray unit has a counterweighted articulating X-ray tube support arm that allows positioning of an attached X-ray tube virtually without the need for moving a supporting carriage. The improved mobile X-ray unit also allows the X-ray tube to be locked to the supporting carriage during travel and the articulating X-ray arm includes several electro-magnetically actuated disk brakes capable of locking the articulating X-ray arm in a predetermined position. In the event that the carriage movement is required, the carriage may be moved by application of force on a force sensing handle engaged with the carriage by two strain gage assemblies. The strain gage assemblies provide signals to a motor drive control circuits which in turn propel two driven wheels in the direction and proportional to the force applied to the handle relative to the carriage.

C23F 100

US Classification:

216 12

Abstract:

Air cross grids, for absorbing scattered secondary radiation and improving X-ray imaging in general radiography and in mammography, are provided with a large plurality of open air passages extending through each grid panel. These passages are defined by two large pluralities of substantially parallel partition walls, respectively extending transverse to each other. Each grid panel is made by laminating a plurality of thin metal foil sheets photo-etched to create through openings defined by partition segments. The etched sheets are aligned and bonded to form the laminated grid panel, which is moved edgewise during the X-ray exposure to pass primary radiation through the air passages while absorbing scattered secondary radiation arriving along slanted paths.

International Classification:

B62D 5104

US Classification:

180 193

Abstract:

A motion controlling system for providing a motion control signal to a motor driving a wheel of a medical equipment carriage is described. The system includes a handle having an end movably supported by the carriage so as to permit movement of the handle end relative to the carriage in a direction in which movement of the apparatus is desired, The system is also provided with an optical position encoding means, coupled between the handle end and the carriage, for providing a position signal indicating the position of the handle end relative to the carriage. A motion control means, responsive to the position signal from the optical position encoding means, provides a motion control signal to the motor. Several embodiments of the optical position encoding means, which include photodiode arrays and solar cells, are described.
