摘要:
An endoscope for quantitatively determining dimensions of an object in a cavity is provided. The endoscope has a projector connected to a light guide that can be introduced through the instrument channel. In the introduced position the projector projects a pattern at a defined illumination angle onto the object to be examined. The endoscope has a camera that captures the projected pattern at a fixed viewing angle in a distorted from corresponding to the object. The distorted form is used for quantitatively determining dimensions of the object by a triangulation method.

In a method for processing a generated digital endoscopy image of a patient, those pixels that depict a body region of a patient are determined as image points in the endoscopy image, in a processor. In the processor, a color value is derived for image point using the value of the associated pixel, and an area portion associated with each image point is derived for the color value. A color area is derived for each color value, as the sum of all area portions of the image points having that color value. An evaluation measure of the endoscopy image is then implemented in the processor using the respective color areas.

In a method and a device to detect information about the three-dimensional structure of the inner surface of a body cavity of a patient with an endoscopy capsule introduced into said body cavity, a first partial region of the inner surface of the body cavity is illuminated with at least one light source arranged in the endoscopy capsule and an image of a second partial region that is illuminated by the first partial region and differs from the first partial region. The three-dimensional structure of the second partial region is known, and the second partial region is acquired with at least one camera arranged in the endoscopy capsule. Information about the three-dimensional structure of the first partial region is derived using the intensity values in this image.

In a method and a device to detect information about the three-dimensional structure of the inner surface of a body cavity (2) of a patient with an endoscopy capsule (4) introduced into said body cavity (2), a first partial region of the inner surface of the body cavity (2) is illuminated with at least one light source (16) arranged in the endoscopy capsule (4): and an image of a second partial region (36) that is illuminated by the first partial region (30) and differs from said first partial region (30), the three-dimensional structure of which second partial region (36) is known, is acquired with at least one camera (18) arranged in the endoscopy capsule (4). Information about the three-dimensional structure of the first partial region (30) is derived using the intensity values present in this image.
摘要:
In a method for diagnosing functional lung illnesses, image exposures of the lungs are obtained at various phase points in time of the respiration of a subject, such as at maximum inhalation and maximum expiration, and the image exposures are segmented and at least two of the image exposures are compared on a segment-by-segment basis to identify a change in tissue density between the compared segments, as an indicator of lung functioning.
摘要:
In a method and system for automated association of an assessor with an assessment task (in particular an evaluation of an image data set) an assessor database is used that contains assessors as well as selection information associated with assessors and task information associated with assessment tasks. A medical assessment is automatically associated with an assessor using at least one decision rule, starting from the task information and with consideration of the relevant selection information.
摘要:
In a method for the administration of medical patient data with a centralized or decentralized patient medical file having secured access enabled by the patient or an enable code administered by the patient, wherein the patient data contain all previous examinations with data representing when the examination was conducted and the findings, a check-in of a patient into the device is implemented before a new examination by the physician, the check-in ensuing upon indication of the initial suspicion as well as of the planned examinations, an enable of these examination via a comparison device, particularly an expert system, ensues only when no relevant, previous examinations are present in a specific, preceding time span, and invoicing for the new examination is possible only in conjunction with a documentation of the examination and its results in the patient medical file.
摘要:
A device is for repeated semi-invasive abrasion of lesions on the walls of hollow organs, in particular blood vessels or the gastrointestinal tract of a patient. The device includes an outer stent which, fixed in position at the site of the lesions, can be clamped against the wall of the hollow organ and has recesses through which the lesions can inwardly protrude. The device further includes a cutting body which is guided within the outer stent and only negligibly narrows the internal bore of the outer stent, which cutting body has cutting edges sliding on the inner side of the outer stent and is coupled magnetically to an external magnet system via which it can turn about the stent axis and/or can move longitudinally along the stent axis.
摘要:
A system HAS at least one medical imaging device for implementing a medical imaging and at least one operating unit. The at least one operating unit is decoupled from the medical imaging device at least for a sample preparation for the medical imaging.
摘要:
In a method or system for limiting use of capsule endoscopes by a capsule endoscope maagnetic steering system used by a customer, the capsule endoscope is provided with a use code stored with the capsule. The use code is read and analyzed to determine whether or not the customer's capsule endoscope magnetic steering system will be enabled or disabled for use with the capsule endoscope from which the use code was read.
