Abstract: The present application relates to a method for registering two-dimensional image data, comprising the steps of: providing a registered three-dimensional image data set of an object under examination; providing a two-dimensional image data set of the object under examination which is to be registered; generating synthetic two-dimensional image data sets of the object under examination from the three-dimensional image data set, wherein the synthetic two-dimensional image data sets to be generated are parameterized with regard to parameters which describe the two-dimensional image data set to be registered; comparing the parameterized synthetic two-dimensional image data sets with the two-dimensional image data set to be registered, and finding the parameterized synthetic two-dimensional image data set having the greatest similarity to the two-dimensional image data set to be registered; on the basis of this, ascertaining the spatial relationship between the two-dimensional image data set to be registered an

Abstract: A system and method of determining a measure of accuracy of a registration mapping combining data indicative of spatial positions in a three-dimensional operating space and imaging data acquired with an imaging device located in a position and orientation in operating space is provided. A phantom is brought into a first pose, wherein the phantom is at least in partial view of the imaging device located in a second pose, the phantom comprising a marker assembly that can be imaged by the imaging device. Image data of the marker assembly of the phantom is acquired with the imaging device in the second pose. Imaged markers in the acquired image data of the marker assembly are located, and mapped markers are obtained by submitting spatial positions of the markers in the marker assembly of the phantom in the first pose to the registration mapping using the second pose as the imaging pose.

Abstract: A marker navigation system for detecting and displaying locations of at least two reference devices, each reference device attachable to a corresponding object includes a detection device for detecting signals emitted from the at least two reference devices, a display device for displaying the locations of the at least two reference devices and/or the objects attached to the at least two reference devices based in accordance with display signals; and a data processing device.

Abstract: A camera system includes at least two camera units, wherein each camera unit comprises at least one detection element for detecting an optical signal. At least one of the at least two camera units includes at least one element operative to enable detection of light in at least two different spectral ranges.

Abstract: A medical x-ray detection device includes an x-ray detector operable to detect the presence of x-ray radiation in a medical environment, and a signal emitter operatively coupled to said x-ray detector. The signal emitter includes at least one active light-emitting signal device, wherein the signal emitter is operative to emit a signal corresponding to the presence of x-ray radiation.

Abstract: A method for optimizing the interpretation of analog image signals or sequences of image signals output by medical image recording devices. The correlation of consecutively recorded image signals is tested and, based on the test, the image signals are identified as depicting the same or different images. More specifically, if the correlation is not less than a particular threshold value, it is established that the image signals depict the same image. If the correlation is less than a particular threshold value, it is established that the image signals possibly depict different images. Further, the threshold value is dynamically adjusted if the correlation has changed.

Abstract: For administering and maintaining a greatest variety of communication systems having a greatest variety of configuration levels and function versions, a modularly structured personal service computer can be connected thereto locally or via communication networks. The adaptability to the greatest variety of communication systems is achieved with the assistance of a software concept wherein administration and maintenance instructions that administer and maintain communication systems are generated individually associated to a communication system and under the control of the user surface and are communicated to the respective communication system. The software concept is based on a software structure comprising four program structures that can be modified by removing or adding program modules given the least influencing of the implemented program modules and that substantially enhances the modularity and adaptability of the personal service computer.
