Abstract: An endoscope system (200, 300) for imaging an interior of a patient (180) comprises an endoscope tube (210, 310), an imaging unit (350) for imaging the interior of the patient, wherein the imaging unit is at least partially located inside the endoscope tube, and an optical coherence tomography unit (360), wherein said imaging unit (350) is distinct from the OCT unit (360), and wherein a sample arm (360c) of the OCT unit is at least partially located inside the endoscope tube.

Abstract: A combined fundus scanning apparatus for optical coherence tomography (OCT) and fundus imaging has an OCT unit (1) with a first light source creating a point-shaped scanning beam, an interferometer with a first sensor for sensing and evaluating the beam reflected by the retina (8), an imaging device (14), which focuses the scanning beam onto the retina (8) of an eye (9) to be examined, as well as a first beam deflection unit (4) to move the scanning beam in the X direction and a second beam deflection unit (11) to move the beam in the Y direction across the retina (8). Fundus imaging is effected by means of a second light source (5) that emits light of a spectral range different from the first light source, which light is also imaged onto the retina (8) via the imaging device (14), and which impinges on a second sensor (10) for sensing the light of the second light source (5) reflected by the retina (8).

Abstract: A method reads out X-ray information stored in a storage phosphor layer where an X-ray picture is obtained and made up from a number of pixels. The method includes the steps of: irradiating the storage phosphor layer with a stimulation light beam which is moved along a line over the storage phosphor layer to stimulate the storage phosphor layer into emitting emission light; collecting emission light emitted from the storage phosphor layer, and converting the emission light collected into a corresponding detector signal S; deducing a number of detector signal values D from the detector signal S, where the number of deduced detector signal values D is greater then a predetermined number of pixels of the X-ray picture along the line; and deducing a picture signal value B for each pixel of the X-ray picture along the line from at least two of the detector signal values D.

Abstract: The components of a fundus camera for observing an eye (11)—namely, an illumination device (1) to illuminate an image field of the eyeground (12) and an image recording device (14) onto which the eyeground (12) is projected by means of a projection device (10)—are positioned to be confocal. The illumination device (1) is so structured that a periodic light pattern is created against the eyeground (12) within the illuminated image field. Further, an offset medium is present to offset the pattern by less than one period. The image recording device (14) is connected to an evaluation unit (22) in order to combine at least three recordings illuminated with offset patterns into a single photograph. A single, unstructured, extremely sharply focused photograph of the eyeground (12) may thus be obtained.

Abstract: An apparatus and associated method for reading out X-ray information of an X-ray picture stored in a phosphor layer includes: an irradiation device for irradiating the phosphor layer with a stimulating light beam to be moved along a line over the phosphor layer, and in so doing stimulating the phosphor layer into emitting emission light; a detector for collecting the emission light emitted from the storage phosphor layer and for converting the emission light collected into a detector signal S; a processing unit for deducing picture signal values B for pixels of the picture along the line from the detector signal S; and two or more sensors located at different reference positions to collect reference times when the light beam is located at the different reference positions. The processing unit deduces a number of detector signal values D from the detector signal S to deduce the picture signal values B between the two reference times.
