Image processing apparatus, image processing method, and program
An image processing apparatus includes a detection unit configured to detect a depolarized region in a polarization tomographic image of a subject's eye, an estimation unit configured to estimate a curve using the extracted depolarized region, a discrimination unit configured to discriminate the extracted depolarized region as a region including the estimated curve and a region which is discontinuous with the region including the estimated curve, and a correcting unit configured to correct at least a portion of a result of the discrimination representing the discontinuous region to a result of discrimination representing another region.

FEED MECHANISM
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.
Device and Method for Reading an Imaging Plate
A device and method for reading an exposed imaging plate generate read-out light and utilize a deflection unit to direct the read-out light in a scanning movement over the imaging plate. The deflection unit has a micromirror to deflect impinging read-out light towards the imaging plate. The micromirror can swivel about a first swivel axis and about a second swivel axis distinct from the first. A detector unit detects fluorescent light emitted from the imaging plate at locations where the read-out light impinges. An evaluating unit evaluates signals received from the detector unit and builds up an image that is stored in the imaging plate. The evaluating unit takes into account, when evaluating the signals received from the detector unit, that points on the imaging plate are subjected to the read-out light variably often and/or for variable time lengths while the micromirror oscillates about the first and the second swivel axis.

Device and method for reading an imaging plate
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.

Arrangement for Controlling Image Plate and Its Image Information and a Method for Controlling the Arrangement
A medical imaging system includes at least an image plate, X-ray device for producing an image of an object on said image plate, and a reading device for reading image information held by the image plate. In connection with the image plate there is a tag containing information for controlling the arrangement in such a manner that when the arrangement has read the information in the tag the arrangement is adapted to perform at least one operation controlled by the information read.
IMAGING PLATE SCANNER
A device for reading out an exposed imaging plate, comprising 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.
