Abstract
The present disclosure provides systems and methods for generating spatial annotations within guidance images that are displayed during a guided medical procedure, where the spatial annotations provide spatial graduations indicating known length measures. The spatial measures may be employed to visually assess the sizes of anatomical and/or functional features displayed in the guidance images.
Claims26
A surgical navigation system comprising:
- computer hardware operatively connectable to a tracking system, said computer hardware comprising at least one processor and memory, the memory comprising instructions executable by said at least one processor for performing operations comprising:
- receiving, from the tracking system, signals from one or more fiducial markers associated with a medical instrument;
- processing the signals to determine a position and an orientation of the medical instrument;
- employing a coordinate transformation to represent pre-operative image data and the position and orientation of the medical instrument within a common frame of reference;
- and
- generating and displaying a navigation user interface comprising:
- anatomical and/or functional features associated with the pre-operative image data;
- a plurality of virtual spatial annotations positioned at prescribed locations along a longitudinal axis of the medical instrument relative to the position of the medical instrument, each virtual spatial annotation having a transverse spatial extent indicating a corresponding different absolute transverse length measure, the transverse spatial extent being determined in a direction orthogonal to the longitudinal axis;
- and
- numeric values of the different absolute transverse length measures that correspond to the virtual spatial annotations, the virtual spatial annotations thereby enabling a visual representation of the size of anatomical and/or functional features proximal to the longitudinal axis.
