    Abstract: This document relates to determining the configuration of a medical imaging system, in particular a configuration which defines a desired viewing direction of the medical imaging system onto a patient. First, a fluoroscopic image of at least a part of a patient is captured using the medical imaging system and the target central beam is set in the fluoroscopic image. Then a target line in space is determined which, when projected into the fluoroscopic image, coincides with the set target central beam. Then the configuration of the medical imaging system is determined such that the central beam of the medical imaging system coincides with the target line in space.

    Abstract: This document relates to technologies of projecting an incision marker onto a patient using a movable gantry carrying a medical imaging system and at least one laser which is adjustable relative to the gantry. The medical imaging system is used for capturing a fluoroscopic or x-ray image of at least a part of the patient from a viewing direction. Then a virtual marker is set in the captured image in order to indicate a point or region of interest, for example as a point or at least one line of an incision. Then the laser is used to indicate, from a projection direction different from the viewing direction, the point or region of interest onto the surface of the patient, thus making the point or region of interest visible from the outside.

    Abstract: A medical data processing method for determining the spatial relationship of a first medical device relative to a second medical device, the method being constituted to be executed by a computer and comprising the following steps: d) acquiring first medical device position data comprising first medical device position information describing the position of the first medical device, wherein the first medical device position data is acquired based on reading, from a marker device having for example a fixed spatial relationship relative to the first medical device, the first medical device position information or information which allows access to the first medical device position information; e) acquiring second medical device position data comprising second medical position information describing the position of the second medical device; f) determining, based on the first medical device position data and the second medical device position data, relative position data comprising relative position information describing the spatial relationship of the second medical device relative to the first medical device.
