An incision marker is projected 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.

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).

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.

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.

A computer-implemented method for determining a target position of an X-ray device 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. Furthermore, a trajectory of an implant positioned within the anatomical structure relative to the patient coordinate system is acquired. 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.

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, &#x2014;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.

A device and method are provided that enable calibration information to be determined for an x-ray apparatus that performs a three-dimensional x-ray scan. The calibration information is determined using an adapting method, wherein the adapting method is based on a position of an x-ray source relative to an x-ray unit marker device during image acquisition, an x-ray unit data set that describes the position of the x-ray unit marker device during image acquisition, and a two-dimensional calibration data set that describes at least one and preferably two actual two-dimensional x-ray images produced by irradiating a calibration object.

The invention relates to a medical instrument comprising an instrument body (), an instrument tip () and a tracking means (), characterized in that said instrument tip () is fitted with a touch-sensor () which detects a contact between said tip () and an object, for example a patient. It is preferably realized as an indicator device or pointer, in particular as a registering pointer for instrument tracking systems.

A system and apparatus for registering image data of a body, wherein the image data are captured in a detection range and the body is subsequently shifted relative to the detection range or vice versa. The image data are registered from the detected position of a first marker array, arranged in a defined positional relationship relative to the body, and from the detected position of a second marker array, arranged in a defined positional relationship relative to the detection range. The apparatus includes a camera and a first marker array that is arranged in a known positional relationship relative to the body, wherein a second marker array is arranged at a fixed position relative to a detection range.

A drive unit for a motor vehicle having a hybrid drive, includes an internal-combustion engine, an electrical rotating machine with a pertaining energy accumulator, a transmission unit, and a control unit. The transmission unit includes at least one starting gear position which can be operated only and exclusively when defined conditions exist during a starting operation from the stationary position of the vehicle. For this purpose, the control unit is constructed such that, as a function of the charge condition of the energy accumulator, the starting operation takes place in a standard gear position of the first ratio, or the starting operation takes place in the starting gear position with a ratio of the transmission unit different from the first ratio.

The accuracy of radiation therapy is enhanced with the blade collimator of the claimed invention. Particularly, this collimator includes a support device for supporting at least two sets of radiation attenuating blades in a single plane or layer. The blades are reciprocally movable within this support. Shaping of the therapy may be increased by constructing the blades to include a varying width increasing from the central blade toward the exterior blades.
