The detected positional data can be assigned to body structure data, in order to jointly use the body structure data in assignment with the positional data, within the context of assisting the treatment. The body structure data can be used which is obtained based on a three-dimensional generic model, where the model is adapted by two-dimensional data linking with patient-characteristic, two-dimensional detection data.
RELATED APPLICATION DATA This application is a continuation-in-part of U.S. application Ser. No. 10/133,867, filed on Apr. 26, 2002, now U.S. Pat. No. 7,194,295 and claims priority of U.S. Provisional Application No. 60/494,935 filed on Aug. 13, 2003, which is incorporated herein by reference in its entirety.
FIELD OF THE INVENTION The present invention relates to a method and device for computer-assisted medical navigation and/or pre-operative treatment planning. In particular, it relates to a method and device for planning and navigation assistance using two-dimensionally adapted and detected patient data.
BACKGROUND OF THE INVENTION Computer-assisted, stereotactic systems, which work with the aid of body structure data obtained from tomographic detection systems and with the assistance of x-ray images produced in situ are known, for example, from U.S. Pat. Nos. 4,791,934 and 5,799,055. X-ray imaging used to assist in operations is discussed in U.S. Pat. Nos. 5,967,982, 5,772,594 and 5,784,431.
SUMMARY OF THE INVENTION In accordance with one aspect of the invention, a method for computer-assisted medical navigation or pre-operative treatment planning can include detecting a position of a patient or a part of a patient's body and detecting positions of medical treatment devices or treatment-assisting devices. The method can further include assigning the detected positions to body structure data, the body structure data being obtained from a three-dimensional generic model.
DETAILED DESCRIPTION OF THE INVENTION In accordance with one aspect of the invention, the current position of a patient or a part of a patient's body and the positions of medical treatment devices or treatment-assisting devices can be detected in such navigation methods by means of a position detection unit, and the detected positional data can be assigned to body structure data, in order to jointly use the body structure data in assignment with the positional data, within the context of assisting the treatment. Such a navigation system is described for example in DE 196 39 615 C2 and corresponding U.S. Pat. No. 6,351,659, which is incorporated herein by reference in its entirety.
This adaptation requires a guideline for transforming the model onto the patient-specific data, which also enables the information stored in the model, for example, a CT or MR data set, to be appropriately modified, such that a �virtual� data set of the patient, including tomographic images, can be used for navigation.
In order to use the three-dimensional model in conjunction with the transillumination images, it has to be adapted (�morphed�) to the information of the images. In one embodiment, the landmarks and other points of interest, which are used for deforming, are projected onto the two-dimensional transillumination images. The deformation of the model is defined by adjusting the predetermined landmarks to the contour of the desired structure.
When �navigation� is mentioned in the following, this term is intended in principle to also include pre-operative treatment planning in the context of which a surgeon determines an ideal approach for a treatment beforehand, for example, manually determines and fixes the ideal position of an implant.
The patient-characteristic data can be x-ray data, from x-ray images produced before or during treatment, such as bi-planar or multi-planar x-ray images. An example of this is when x-ray images of the patient are already available, which were produced within the context of previous examinations. Data about body structures from these �old� x-ray images is particularly suitable if deviations of form with respect to the generic model are to be calculated in.
It is, however, also possible, even during treatment, to produce individual x-ray images of the patient and to include this information in adapting the generic model. The advantage as compared to conventional �x-ray navigation� is then that it is not necessary to produce a large multitude of x-ray images, such as are used in navigation based on x-ray images. It is sufficient for adapting the generic model to produce just one or very few x-ray images, which, moreover, can be restricted to a very small section of the body. This significantly reduces the radiation load as compared to conventional x-ray navigation.
