Abstract:
The present disclosure is directed to an augmented reality surgical system. The system includes an endoscope that captures an image of the region of interest of a patient and an ECG device that records an ECG of the patient. A controller receives the image and applies at least one image processing filter to the image. The image processing filter includes a decomposition filter that decomposes the image into frequency bands. A temporal filter is applied to the frequency bands to generate temporally filtered bands. An adder adds each band frequency band to a corresponding temporally filtered band to generate augmented bands. A reconstruction filter generates an augmented image by collapsing the augmented bands. The controller also receives the ECG and processes the augmented image with the ECG to generate an ECG filtered augmented image. A display displays the ECG filtered augmented image to a user.
