摘要： An apparatus for processing image data is disclosed. The apparatus includes one or more processors. The apparatus determines a feature in a cross-sectional image of a live tissue. The apparatus determines a superimposed image by superimposing a reference on the cross-sectional image or a subsequent cross-sectional image of the live tissue. The reference is based on the determined feature. An output interface outputs image data of the superimposed image for display.

摘要： Examples relate to a system for a microscope system, to a microscope system comprising such a system, and to a corresponding method and computer program. The system comprises one or more processors and one or more storage devices. The system is configured to obtain a trigger signal. The trigger signal indicates a desire of a user of the microscope system to display a visual representation of a control functionality associated with an input device of the microscope system. The system is configured to generate, based on the trigger signal, a visual overlay comprising the visual representation. The system is configured to provide a display signal to a display device of the microscope system, the display signal comprising the visual overlay.

摘要： An apparatus is disclosed which is to identify a feature of an image captured from a first focal plane; determining a focus position relative to the first focal plane; and to determine an aperture setting. At the focus position and the aperture setting, a depth of field is provided. The apparatus may be further configured to determine at least one of a second plane and a third plane relative to the first focal plane. At the focus position and the aperture setting, the at least one of the second plane or the third plane is in focus.

摘要： Examples relate to apparatuses, methods and computer programs for controlling a microscope system, and to a corresponding microscope system. An apparatus for controlling a microscope system comprises an interface for communicating with a camera module. The camera module is suitable for providing camera image data of a head of a user of the microscope system. The apparatus comprises a processing module configured to obtain the camera image data from the camera module via the interface. The processing module is configured to process the camera image data to determine information on an angular orientation of the head of the user relative to a display of the microscope system. The processing module is configured to provide a control signal for a robotic adjustment system of the microscope system based on the information on the angular orientation of the head of the user.

摘要： Examples relate to a microscope system comprising a Light-Emitting Diode (LED)-based illumination system and at least one image sensor assembly, and to a corresponding system, method and computer program. The LED-based illumination system is configured to emit radiation power having at least one peak at a wavelength that is tuned to an excitation wavelength of at least one fluorescent material and/or to emit radiation power across a white light spectrum, with the light emitted across the white light spectrum being filtered such that light having a wavelength spectrum that coincides with at least one fluorescence emission wavelength spectrum of the at least one fluorescent material is attenuated or blocked. The at least one image sensor assembly is configured to generate image data, with the image data (at least) representing light reflected by a sample that is illuminated by the LED-based illumination system. The microscope system comprises one or more processors, configured to process the image data to generate processed image data.

摘要： A medical imaging apparatus (1) and method for imaging a light-sensitive object (2), such as tissue (3) of the eye (4), displays the object (2) in spectral bands (30) of the visible light range (37) in which the object is sensitive and cannot be illuminated. The apparatus (1) has a camera (8) for capturing input images (10) in which a spectral signature (36) of the object is represented by an input set (15) of spectral bands (16). The apparatus generates output images (22) in which the spectral signature (60) in the visible light range (37) is represented by an output set (29) of spectral bands (30). Replacing at least one input-only spectral band (38) in the input set (15) by at least one output-only spectral band (39) in the output set (29) enables capture of input images (10) in spectral bands (16) where the object (2) has less sensitivity, such as in the non-visible light-range (18), and display of the object (2) in spectral bands (30) where the object would be too sensitive for illumination (40).

摘要： The invention relates to an apparatus (1) and method for automatically determining the blood flow direction (42) in a blood vessel (14) using the fluorescence light from a fluorophore (16). Blood flow direction (42) is determined by first identifying a blood vessel structure (38) in an input frame (6) from a camera assembly (2) using a pattern recognition module (26). Blood flow direction (42) is determined from the spatial gradient (dI/dx) of the fluorescence intensity (I) along the identified blood vessel structure (38) and the temporal gradient (dI/dt). An output frame (48) is displayed on a display (36) with time-varying marker data (52) overlaid on the identified blood vessels structure (38) and representative of the blood flow direction (42).
