7680528 Method for the graphical representation of a medical instrument inserted at least partially into March 16, 2010
The invention provides a method for the graphical representation of a medical instrument inserted at least partially into an object under examination, with an image representing the medical instrument being generated, in that the instrument image is vectorized, with the medical instr
7580503 Diagnostics device comprising an X-ray system with coordinated frequency operation August 25, 2009
The invention relates to a diagnostics device and to a method for the operation thereof comprising an X-ray system for producing X-ray images, the system comprising an X-ray device and an image system for the X-ray device, and a system for locating objects, wherein adjusting means for
7460642 Method for generating an x-ray image sequence December 2, 2008
With a method for generating an x-ray image sequence for supporting an intervention on a patient with a catheter or guide wire for instance, automatic recognition of the catheter is carried out with recorded x-ray images using a computer system. The x-ray image recording parameters are
7331711 Method and foot switch control for fast angulation changes in an x-ray system February 19, 2008
In a method for fast angulation changes in a C-arm x-ray system, and a foot switch for effecting such fast angulation, a pedal of the foot switch that normally has a function not related to angulation of the C-arm is either permanently, or temporarily programmed, to operate as a peda
7248674 Diaphragm unit for an x-ray device July 24, 2007
The invention relates to a diaphragm unit 4 or a diaphragm unit 4 and an associated x-ray emitter 1 with adjustment option for displaying an asymmetrical area under examination, with the diaphragm unit 4 being able to be tilted in accordance with the invention relative to the x-ray e
7236567 Method and apparatus for synchronizing operation of an x-ray system and a magnetic system June 26, 2007
An x-ray apparatus has a flat panel x-ray detector, the operation of which is susceptible to interference by strong magnetic fields. In order to allow the x-ray system to be operated concurrently with a magnetic system, such as a magnetic tracking system or a magnetic localization sy
7212612 X-ray device May 1, 2007
X-ray device with a detector and an adjustable diaphragm for fading-in an examination area, whereby the detector (6) can be controlled and read-out asymmetrically and the diaphragm (8) can be moved asymmetrically.
