Abstract: Provided is a method for determining a position of an imaged anatomical body part of a patient. The method includes acquiring patient image data describing a digital image of at least part of a reference device and the anatomical body part, acquiring reference device model data describing a model of at least one of at least one internal surface or at least one external surface of the reference device, determining, —based on the patient image data and the reference device model data, reference device image position data describing a relative position between the reference device and the anatomical body part, acquiring reference device tracking data describing a position of the reference device in the tracking reference system, and determining, based on the reference device image position data and the reference device tracking data, body part tracking data describing a position of the anatomical body part in the tracking reference system.

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: Disclosed is a computer-implemented method for determining a target position of an X-ray device which encompasses acquiring image data describing an anatomical structure of a patient, for example, by means of a 3D scan, and registering the image data relative to a coordinate system of the patient, for example by means of a navigation system (embodied by registered image data). Furthermore, a trajectory of an implant positioned within the anatomical structure relative to the patient coordinate system is acquired (embodied by trajectory data). A target position of an X-ray device for acquiring an X-ray image of at least part of the implant is determined based on the registered image and the acquired trajectory of the implant (embodied by X-ray device position data).

Abstract: Provided is a medical imaging apparatus having an AR-visualization module operably coupled to a camera and to a position determination module, which is adapted to create an AR-image based on an image received from the camera and an AR-overlay positionally registered with the image, and which includes a display interface adapted to transmit the created AR-image to a medical display.
