Abstract: A medical device, such as a mobile C-arm, is positioned and/or aligned via a touch-sensitive control panel of a tablet. The touch-sensitive control panel provides access to one or more function units, for example, for initiating control signals for a positioning and/or an alignment of the medical device, or a second function unit for specifying a direction of movement for a mobile medical unit, or a third function unit for specifying a motion speed for the mobile medical device.

Abstract: In an imaging acquisition system and method, successive x-ray images and successive optical images are respectively acquired from an examination subject. Positional identifiers associated with the examination subject are detected in the optical images, and acquisition of respective x-ray images is triggered only when the identifiers are detected in the optical images. The number of acquired x-ray images is therefore substantially fewer than the number of acquired optical images, and the x-ray images can be acquired with substantially no overlap, thereby avoiding exposing the examination subject to unnecessary radiation.

Abstract: In a method and apparatus for image support of an operative procedure implemented with a medical instrument, a two-dimensional x-ray image of a volume region to be treated is generated and stored with a C-arm x-ray apparatus in at least one pivot position of the C-arm. With a position detection device, the position of an apparatus reference system and the position of a reference system in the image generation are at least indirectly detected. Between the reference system and an image coordinate system of the x-ray image, a transformation rule is determined using known, apparatus-specific mapping rules that are measured and stored in a preceding calibration. During the subsequent procedure, with the position detection device the position of an instrument reference system is detected in the reference system and the instrument is mixed into the stored two-dimensional x-ray image with accurate position by means of this transformation rule.

Abstract: A method for displaying images in a medical navigation system assisted by x-ray images includes calibrating an x-ray device in the medical navigation system and producing a plurality of two-dimensional x-ray images of a patient using the x-ray device. During the producing step, positions of the x-ray device are determined using the medical navigation system in order to produce positional data. Data associated with the two-dimensional x-ray images is converted into three-dimensional data. The two-dimensional x-ray images, production information corresponding to the two-dimension x-ray images, and the three-dimensional data to the navigation system. At least the two-dimensional x-ray images are displayed on an image output of the medical navigation system.
