摘要： A feed mechanism, which is capable of suppressing feed irregularity caused by the inclination of a nut of a feed screw, is obtained. A feed mechanism (sub-scanning mechanism) includes a feed screw that includes a screw shaft and a nut and a moving body, and the nut is moved on the screw shaft by a rotation of the screw shaft, so that the moving body is moved in the direction of the screw shaft. The inclination of the moving body with respect to the nut is allowed in a case in which the moving body is moved by a movement of the nut.

摘要： A device for reading out an exposed imaging plate, having a light source producing a read-out light, a deflecting unit sequentially directing the read-out light at the imaging plate with a read-out spot in order to read out the imaging plate, whereby a traveling read-out spot can be produced there, a detector unit for fluorescent light, which is emitted by the imaging plate during the reading out by means of the read-out light, and a control device for controlling the light source, the deflecting unit, and the detector unit. The control device performs a preliminary read-out of the imaging plate in order to determine read-out parameters and to subsequently read out the imaging plates using the determined read-out parameters. A method for reading out an imaging plate reading out part of the information on the imaging plate surface, determining read-out parameters on the basis of the read-out part of the information, and reading out the remaining part of the information of the imaging plate surface using the read-out parameters.

摘要： A device configured to read an exposed imaging plate, comprises a light-source that generates read-out light. A deflection unit directs the read-out light in a scanning movement over the imaging plate. The deflection unit comprises a micromirror that deflects impinging read-out light towards the imaging plate. The micromirror swivels about a first swivel axis and about a different second swivel axis. The micromirror oscillates with a first frequency about the first swivel axis and simultaneously with a different second frequency about the second swivel axis. A detector unit detects fluorescent light which is emitted from the imaging plate at locations where the read-out light impinges.

摘要： A method for reading out image information stored in a storage phosphor of a storage medium includes moving a light beam over the storage medium. A luminescence signal is generated by the photostimulation of the storage phosphor. In first time intervals a respective output value is determined from the luminescence signal, and a respective pixel value of an image pixel of a digital image is determined from the output value. The output value is thereby determined by addition of a plurality of measurement values of the luminescence signal which are detected in second time intervals lying within the first time interval. A corresponding apparatus for carrying out the method is described as well.

摘要： A scanning apparatus that can operate as both a computed and direct style radiography device. In the computed radiography mode, an internal imaging plate is removed or maintained inwardly within the housing assembly to allow a cassette handling mechanism holding a removable imaging plate to pass adjacent the scanning head. In the direct radiography mode, the cassette handling mechanism is retracted and the internal imaging plate is moved outward from the within the housing such that it is located adjacent the reading slot of the scan head assembly. In both modes of operation, the imaging plate being used is maintained adjacent the scan head while the scan head and imaging plate surface are moved relative to each other allowing the scanning and acquisition of the image data stored on the plate.
