Registering image information
First Claim
1. A method for registering and/or re-registering image information by means of a medical navigation system, wherein:
- current image information of a patient to be registered using the navigation system is produced using an image information detection device;
the position of the image information detection device is established by means of the navigation system;
the current image information is compared with the aid of a computer with previously acquired image information;
in the event of a difference between the image content of the current and previously acquired image information, a new relative position of the image information detection device and the patient is detected and stored; and
the current image information produced is registered in the navigation system, based on the information on the new relative position.

Abstract
The invention relates to a method for registering image information by means of a medical navigation system, wherein:
current image information, in particular a current x-ray image of a patient to be registered using the navigation system, is produced;
the position of the image information detection device, in particular of the x-ray device, is established by means of the navigation system;
the current image information, in particular the current x-ray image, is compared with the aid of a computer with other image information (for example, a previously taken x-ray image);
in the event of a difference between the image content of the current and previous image, the new relative position of the image information detection device or x-ray device respectively and of the patient is detected and stored; and
the current image information produced or current x-ray image produced, respectively, is registered in the navigation system, based on the information on the new relative position.
The invention further relates to: a program which, when run on a computer or loaded in a computer, causes the computer to carry out the method; a computer program storage medium comprising such a program; and an x-ray image registering means.

8. An x-ray image registering means comprising a medical navigation system, an x-ray device with which a current x-ray image is produced of a patient to be registered using the navigation system, the navigation system including a means by which the position of the x-ray device is established, characterised by an image comparing means with which the current x-ray image is compared with the aid of computers with previous image information, as well as by a detecting and storing means with which, in the event of a difference between the image content of the current and previous image information, the new relative position of the x-ray device and the patient is detected and stored, whereby the current x-ray image produced can be highly accurately re-registered in the navigation system, based on the information on the new relative position.

11. A method for registering image information by means of a medical navigation system, comprising the steps of:
-
using an image information detection device to acquire current image information of a patient;
comparing the current image information with previously acquired image information of the patient to determine if a difference exists between the compared image information; and
in the event of a difference between the image content of the current and previously acquired image information, registering the current image information of the patient in the navigation system based on current positions of the image information detection device and the patient as determined by the navigation system. - View Dependent Claims (12, 13, 14, 15)
