Abstract: In a method for determining the projection geometry of an x-ray apparatus, an x-ray image of an object inside the patient is generated using the x-ray apparatus. A first measurement of a characteristic dimension of the imaged object is determined in the x-ray image. A second measurement of the characteristic dimension is determined using real geometry data of the object. The projection geometry is then determined using the first and second measurements.

Abstract: The device enables the detection of positions of the navigation marking elements on a reference star by way of at least two projection images taken by an X-ray system at different pivoting angles of a C-arm. The positions of the navigation marking elements on the reference star are also calculated by a navigation system tracking camera. The transformation from the coordinate system of the navigation system into the coordinate system of the X-ray system is calculated from the position of the reference star detected by the X-ray system and the position of the reference star detected by the tracking camera. The navigation marking elements are located outside of the volume which is reconstructed by way of the imaging process in order to prepare tomographic images. The positions of the navigation marking elements are determined from two-dimensional projections. All the navigation marking elements need only be detected by at least two projection images.

Abstract: In a device and method for processing and presenting x-ray images, an x-ray image of a subject is acquired with an x-ray acquisition cone simultaneously with the acquisition of an optical exposure of the examination subject with an optical acquisition cone that is congruent with the x-ray acquisition cone. The subject in the optical exposure is subjected to segmentation and/or edge extraction, and the extracted optical exposure and the x-ray image are additively combined so that the subject edges from the optical exposure are inserted into the x-ray image.

Abstract: In a method for improving profitability of a medical procedure supervised through a medical facility, the medical procedure including ingestion of an endoscopy capsule by a patient of the medical facility, the endoscopy capsule is retrieved after being naturally voided by the patient after the endoscopy capsule traverses the gastrointestinal tract of the patient, and a reward is paid to a person who returns the retrieved endoscopy capsule to a location associated with the medical facility. An endoscopy capsule usable with this procedure has a capsule body containing medical data-gathering components, and an exchangeable cover that covers the capsule body that is formed of a material allowing removal of the cover after the capsule has passed through the gastrointestinal tract of the patient, so that a new cover can be provided on the capsule body.
