Abstract
To improve the overall navigation process for minimally invasive repair of heart valve leaflets, an augmented reality technique capable of providing a robust three-dimensional context for transesophogeal echocardiography data has been developed. In the context of various embodiment of the invention, augmented reality essentially refers to a system in which the primary environment is virtual but the environment is augmented by real elements. In this real-time environment, the surgeon can easily and intuitively identify the tool, surgical targets, and high risk areas, and view tool trajectories and orientations.
Claims22
A surgical navigation system, comprising:
- a heart valve repair device;
- a medical imaging system, the medical imaging system including an imaging probe that is movable relative to a patient to provide real-time imaging data of anatomy of the patient;
- a tracking system adapted to track location and orientation data of the heart valve repair device and the imaging probe in real-time three-dimensional space, the tracking system including a plurality of sensors that provide the location and orientation data, with at least one sensor incorporated into the heart valve repair device and at least one sensor incorporated into the imaging probe;
- a computer processor adapted to receive the imaging data from the medical imaging system and the location and orientation data from the tracking system, the processor further adapted to create virtual geometric models of the heart valve repair device and the imaging probe;
- at least one display device, the display device operably connected to the computer processor and adapted to present the virtual geometric models of the heart valve repair device and the imaging probe overlain onto the real-time imaging data in a common coordinate system, the virtual geometric models moving in real-time according to the location and orientation data.
A method of providing a surgical navigation system, comprising:
- incorporating at least one sensor into an imaging probe of a medical imaging system;
- incorporating at least one sensor into a heart valve repair device;
- obtaining real-time imaging data of anatomy of a patient with the imaging probe;
- using a computer processor to automatically create virtual geometric models of the imaging probe and the heart valve repair device;
- using a computer processor to automatically overlay the virtual geometric models of the imaging probe and the heart valve repair device onto the imaging data in a common coordinate system on a display;
- and
- using a computer processor to automatically represent a location and orientation of each of the imaging probe and the heart valve repair device in real-time three-dimensional space on the display with tracking information obtained by the sensors.
A surgical navigation system, comprising:
- means for repairing a heart valve of a patient;
- means for providing real-time imaging data of anatomy of the patient;
- means for tracking location and orientation data of the means for repairing a heart valve and the means for providing real-time imaging data in real-time three-dimensional space, the means for tracking including at least one means for sensing location and orientation incorporated into the means for repairing a heart valve and at least one means for sensing location and orientation incorporated into the means for providing real-time imaging data;
- means for creating virtual geometric models of the means for repairing a heart valve and means for providing real-time imaging data and overlaying the geometric models onto the real-time imaging data in a common three-dimensional coordinate system;
- means for displaying the virtual geometric models overlain onto the real-time imaging data showing the location and orientation data in real-time.
