Abstract: Methods and systems for providing feedback during a medical procedure. The 3D position and orientation of a tracked tool are determined, relative to a site of the medical procedure, based on tracking information received from a tracking system. The 3D position and orientation are mapped to a common coordinate space, to determine the 3D position and orientation relative to a field-of-view (FOV) of an optical camera that is capturing an optical image of the site. Navigational information associated with the 3D position and orientation is determined. A virtual representation of the navigational information overlaid on the FOV and displayed. The displayed virtual representation is updated when the 3D position and orientation of the tracked tool changes or when the FOV changes, in accordance with the change.

Abstract: A multispectral synchronized imaging system is provided. A multispectral light source of the system comprises: blue, green and red LEDs, and one or more non-visible light sources, each being independently addressable and configured to emit, in a sequence: at least visible white light, and non-visible light in one or more given non-visible frequency ranges. The system further comprises a camera and an optical filter arranged to filter light received at the camera, by: transmitting visible light from the LEDs; filter out non-visible light from the non-visible light sources; and otherwise transmit excited light emitted by a tissue sample excited by non-visible light. Images acquired by the camera are output to a display device. A control unit synchronizes acquisition of respective images at the camera for each of blue light, green light, visible white light, and excited light received at the camera, as reflected by the tissue sample.

Abstract: A camera system for providing images with simultaneous high resolution and large depth of field is provided. The system includes: a camera device having a field of view, the camera device configured to automatically acquire: a first image of the field of view at a first numerical aperture; and a second image of the field of view at a second numerical aperture smaller than the first numerical aperture; an image processing unit configured to combine the first image with the second image into a single image by: extracting a higher-resolution in-focus portion of the first image; and replacing a corresponding lower-resolution portion of the second image with the higher-resolution in-focus portion of the first image; and, a display device in communication with the image processing unit, the display device configured to render the single image.
