Medical navigation and/or pre-operative treatment planning with the assistance of generic patient data
First Claim
1. A method for computer-assisted medical navigation and/or pre-operative treatment planning, comprising:
- linking a generic model with patient-characteristic data to obtain body structure data;
detecting a current position of a patient or a part of a patient'"'"'s body and positions of medical treatment devices or treatment-assisting devices by a position detection unit, wherein said detected positional data are assigned to the body structure data in order to jointly use said body structure data in assignment with said positional data within the context of assisting the treatment;
obtaining additional points on the patient in the form of landmarks or randomly acquired points; and
using the additional points to further correlate the body structure data to the patient or part of the patient'"'"'s body.

Abstract
The invention relates to a method for computer-assisted medical navigation and/or pre-operative treatment planning, wherein 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 are detected by means of a position detection unit, and wherein said detected positional data are assigned to body structure data, in order to jointly use said body structure data in assignment with said positional data, within the context of assisting the treatment, wherein body structure data are used which are obtained based on a generic model which has been adapted by linking it with patient-characteristic detection data.

13. A method for computer-assisted medical navigation and/or pre-operative treatment planning, comprising:
-
detecting a current position of a patient or a part of a patient'"'"'s body and positions of medical treatment devices or treatment-assisting devices by a position detection unit, wherein said detected positional data are assigned to body structure data in order to jointly use said body structure data in assignment with said positional data within the context of assisting the treatment, and wherein said body structure data are obtained based on a generic model which has been adapted by linking the generic model with patient-characteristic detection data, wherein said patient-characteristic data are diagnostic data obtained from the patient, said diagnostic data obtained from at least one of the following, alone or in combination; x-ray image data from x-ray images produced before or during treatment; bi-planar or multi-planar x-ray images; computer tomography or nuclear spin tomography image data; digitally reconstructed x-ray image data (DRRs=digitally reconstructed radiographs); acquired point-positional information of the patient'"'"'s body structure using natural or artificial landmarks; data on size, weight or lengths of the body section or one or more limbs of the patient.

14. A method for computer-assisted medical navigation and/or pre-operative treatment planning, comprising:
-
detecting a current position of a patient or a part of a patient'"'"'s body and positions of medical treatment devices or treatment-assisting devices by a position detection unit, wherein said detected positional data are assigned to body structure data in order to jointly use said body structure data in assignment with said positional data within the context of assisting the treatment, and wherein said body structure data are obtained based on a generic model which has been adapted by linking the generic model with patient-characteristic detection data, wherein said generic model can be adapted using one or more of the following methods; manually adapting with the assistance of image representation; automatic image fusion methods based on automatically identifying particular anatomical features; and registering and/or fusing image data of said generic model digitally reconstructed x-ray images, and the same from computer tomography or nuclear spin tomography image data sets, after which the adapted body structure data are calculated by computer-assistance. - View Dependent Claims (15)

16. A computer program embodied on a computer readable medium for computer-assisted medical navigation and/or pre-operative treatment planning, comprising:
-
code that links a generic model with patient-characteristic data to obtain body structure data; code that detects a current position of a patient or a part of a patient'"'"'s body and positions of medical treatment devices or treatment-assisting devices by a position detection unit, wherein said detected positional data are assigned to the body structure data in order to jointly use said body structure data in assignment with said positional data within the context of assisting the treatment; code that obtains additional points on the patient in the form of landmarks or randomly acquired points; and code that uses the additional points to further correlate the body structure data to the patient or part of the patient'"'"'s body.
