Abstract
The invention relates to a method for displaying the position and orientation of a linear instrument (1) navigated with respect to a 3D medical image (V), wherein: said linear instrument (1) is coupled to a guide (2); the guide (2) is tracked by a navigation system with respect to the 3D image (V); a plane (4) containing the axis of the linear instrument (1) is virtually attached to the guide (2); a slice reformatted in the 3D image and containing said plane (4) is displayed. Another object of the invention is a system for carrying out said method.
Claims12
A method for displaying a position and orientation of a linear instrument navigated with respect to a 3D medical image, wherein:
- said linear instrument is coupled to a guide;
- the guide is tracked by a navigation system with respect to the 3D image;
- a plane containing an axis of the linear instrument is virtually attached to the guide;
- a slice reformatted in the 3D image and containing said plane is displayed.
A system for displaying a position and orientation of a linear instrument navigated with respect to a 3D medical image, comprising:
- a processor adapted to be coupled to a navigation system to receive navigation data,
- a guide intended to be coupled to the linear instrument and tracked by the navigation system, wherein a plane containing an axis of the linear instrument is virtually attached to the guide so as to allow tracking said plane virtually attached to the guide by the navigation system with respect to the 3D image, the processor being configured to compute a slice reformatted in the 3D image and containing said plane, and
- a display coupled to the processor and configured to display said reformatted slice.
