摘要： The invention relates to a medical observation device (1) such as a microscope or endoscope. Further, the invention relates to a method for processing medical images. Input image data (52) are generated by a visible-light camera (28) and overlaid with auxiliary input data (58) such as fluorescent-light image data (65) generated from auxiliary input data (58) e.g. a fluorescence camera (32) or an ultrasound sensor (40, 42). From the auxiliary input data (58), subsequent sets (84) of pseudo-color image data (86) are generated by an image processor (80). The pseudo-color images (84) are merged with the input image data (52) to obtain output image data (94). A pseudo-color pattern field (88) comprising at least one of a temporally and/or spatially modulated pattern (87) is generated depending on the content of at least one of the image input data (52) and the auxiliary input data (58).

摘要： The invention relates to an image processing method and a medical observation device (1) such as a microscope (2) or endoscope. The device and method are used for displaying output image data (54) of soft biological tissue (12). In image-guided surgery, pre-operative three-dimensional image data (6) of the soft biological tissue (12) are elastically matched to interoperative image data (14) which are acquired during surgery. By displaying the elastically matched pre-operative three-dimensional image data (6) together with the interoperative image data (14), the surgeon may be made aware of the consistence of the soft biological tissue (12) below the visible surface layer. Existing systems for image-guided surgery need to be manually readjusted if surgery is done on soft biological tissue (12), which may deform and shift. To avoid this, the device and method according to the invention perform an elastic matching of the pre-operative three-dimensional image data (6) based on the interoperative image data (14) of the soft biological tissue (12). At least one vascular plexus structure (48) is first identified in the interoperative image data (14) and then the same vascular plexus structure (48) is identified in the pre-operative three-dimensional image data (6). The vascular plexus structure (48) in the pre-operative three-dimensional image data (6) is then elastically matched to the vascular plexus structure (48) in the interoperative image data (14). Output image data (54) are generated combining the elastically matched pre-operative three-dimensional image data (6) to the interoperative image data (14). Preferably, the at least one vascular plexus structure (48) is identified using fluorescent light from a fluorophore (22) which has been injected into the soft biological tissue (12).

摘要： The invention relates to a method, in particular a fluorescence microscopy or endoscope imaging method for intensity normalization, a non-transient computer readable storage medium (101) and a controller (51) for an endoscope (3) or microscope device (5). In the prior art, common observation devices (1) as surgical microscopes, endoscopes (3) or microscopes (5) have the disadvantage that it is ambiguous whether a detected intensity (97) is due to fluorophore (29) concentration or due to optics setting parameters (73). The inventive method overcomes said disadvantages by automatically adjusting at least one exposure control parameter (83) if at least one optics setting parameter (73) is changed. The inventive non-transient computer readable storage medium (101) is adapted to run a program for executing the inventive method and the inventive controller (51) comprises an input section (67) for receiving optics setting data (71); an output section (69) for outputting exposure control data (81); and a determination module (53) for determining at least one exposure control data (81) dependent on at least one optics setting data (71).

摘要： The invention relates to a method for observing an object (33) using a medical observation apparatus (1), such as a microscope (3), a non-transient computer readable storage medium (95) and a medical observation apparatus (1). Solutions of the art are expensive, bulky and prevents further usage of a microscope (3) is e.g. a robotic arm has a malfunction. The inventive method and medical observation apparatus (1) solves those problems by directing an optical assembly (7) to an object (33) located in a field of view (31), and by keeping the object (33) in focus when the optical assembly (7) is manually shifted, essentially perpendicularly to a viewing axis (17) of the optical assembly (7). The inventive apparatus (1) comprises an optical assembly (7) providing an optical viewing axis (17) and a lens adjustment assembly (29) which is configured to direct the optical assembly (7) to the object (33) in dependence on position data (65).

摘要： The invention relates to a beam splitter device (1) for a microscope (2), in particular a stereoscopic microscope and to a microscope imaging method, in particular a stereoscopic microscope imaging method. The beam splitter device (1) supports at least two beamsplitting surfaces (4, 14). Each of the at least two beamsplitting surfaces (4, 14) has a different reflection-to-transmission ratio. The beam splitter device (1) further comprises an optical path (3, 3a, 3b). At least one of the at least two beamsplitting surfaces (4, 14) are configured to be moved from a first operation position (15), in which a first (4) of the at least two beamsplitting surfaces (4, 14) is located in the optical path, to a second operation position (16), in which a second (14) of the at least two beamsplitting surfaces (4, 14) is located in the optical path. With this configuration, it is possible to change the available light in the branches (3a, 3b) of the optical path (3) after the beamsplitting surface (4, 14). This is particularly useful if one of the branches (3a, 3b) is directed to an exit port (8) which is configured to receive a camera. By directing more light to the camera exit port (8), the image quality of the camera can be improved.

摘要： The invention relates to an Illumination and observation system (1), in particular for an ophthalmic microscope. The system comprises a first observation pupil (4) and a second observation pupil (5) for the eyes of an observer such as an assistant. Further, the system comprises a coaxial illumination (6) in the first observation pupil (4) and a main illumination (7), the coaxial illumination (6) being adapted to generate a red reflex (13) in the observed eye in operation and the main illumination having a larger field of illumination than the coaxial illumination (6, 10, 11). In order to facilitate usage of the system (1) and/or the microscope (2) and to create a superior stereoscopic view using the red reflex (13), a control subsystem (21, 27) is provided which is adapted to automatically adjust an intensity of the main illumination (7) depending on a change in an intensity of the coaxial illumination (6).

摘要： The invention relates to a microscope or endoscope assembly (1), in particular for a surgical microscope such as an ophthalmic microscope. Especially in eye surgery, but also in other application concerning life tissue, specular reflections of the illumination light are unwanted because they may hide important information contained in a diffuse reflection at the same location. In order to suppress such unwanted specular reflection, the microscope or endoscope assembly according to the invention comprises an observation region (4), in which an object (6) to be observed, such as an eye, can be arranged. The assembly further comprises an illumination light path (8) which extends from an illumination light entry region (24), where illumination light enters into the assembly, to the observation region. Further, an observation light path (10) is comprised, which extends from the observation region (4) to a light exit region (34), where the light leaves the assembly and may be collected by an observation subassembly (36), such as at least one camera and/or at least one ocular. In the illumination light path, a first polarizing subassembly (16) is arranged, to create polarized illumination light (18). In the observation light path (10) a second polarizing subassembly (32) is arranged, which is configured to filter out the polarized illumination light (18) passing the first polarizing subassembly (16). To ensure coaxial illumination and observation of the object, a beam splitter (30, 40) is provided, which is arranged in the illumination light path (8) between the light entry region (24) and the observation region (4) and in the observation light path (10) between the observation region (4) and the light exit region (34). By the complementary filtering action of the first and second polarizing subassembly, specular reflections by the object can be suppressed and/or eliminated.
