Abstract:
A scanning apparatus is provided, which includes a medium (14) attached to a surface of a fixed, hollow cylindrical segment (12), the fixed, hollow cylindrical segment having a first longitudinal axis (16), a rotational radial laser beam rotating around the first longitudinal axis and arranged to scan said medium, and a light sensitive detector (20) having a light acceptance direction along a second axis coinciding with the first longitudinal axis of the cylindrical segment.
Abstract:
For use with an optical scanning device, a reading head comprising a housing having at least one bore for accommodating therein a respective photo-multiplier tube and a non-intersecting lateral bore for accommodating therein a stimulating light source for producing a stimulating beam having a first wavelength. A focusing lens is mounted in association with the stimulating light source for focusing the stimulating beam on a film of the scanning device so as to produce stimulated fluorescent light having a second wavelength in the film at a point of contact by the stimulating beam. A window is provided within the housing for mounting therein a filter for transmitting therethrough the stimulated fluorescent light whilst substantially blocking reflections of the stimulating beam. The housing is mounted in spaced relationship with the film so as to direct the stimulating light beam perpendicular to the film such that a distance from the film to an internal periphery of the lateral bore within the housing is equal to a focal length of the focusing lens, and the stimulating light source is fixed within the lateral bore so that the focusing lens is in precise registration with the internal periphery.

Abstract:
In one example, distributed computed radiography (CR) systems are disclosed, in which individual networked CR systems are deployed in different doctors' offices, clinics, and the like, or different rooms of a radiography center, such as that found in a radiology department of a medical facility. The individual networked CR systems may be deployed conveniently near to radiation exposure apparatus, so as to facilitate the overall process of patient exposure and image acquisition/processing. Images acquired from different networked CR systems may be transported to other systems coupled to the distributed CR network, and/or archiving facilities, for processing, storage, cataloging, analysis, etc. In another example, redundant computed radiography systems are disclosed, including multiple independently controllable scanners coupled to a single controller/processor at a given location. Such redundant systems improve image scanning/acquisition throughput and system robustness.

Abstract:
A method of acquiring at least one image from an image recording medium using a pulsed radiation source is provided. In one aspect, a method of scanning an image recording medium that has been exposed to X-ray radiation comprises providing first radiation along a plurality of scan traces over a surface of the image recording medium such that the first radiation does not impinge on the image recording over at least one interval along each of the plurality of scan traces. The pulsed laser source may reduce and/or eliminate cross-influence artifacts in images resulting from pulsed radiation image acquisition.
