Abstract: A stereoscopic visualization camera and platform are disclosed. An example stereoscopic visualization camera includes a main objective assembly and left and right lens sets defining respective parallel left and right optical paths from light that is received from the main objective assembly of a target surgical site. Each of the left and right lens sets includes a front lens, first and second zoom lenses configured to be movable along the optical path, and a lens barrel configured to receive the light from the second zoom lens. The example stereoscopic visualization camera also includes left and right image sensors configured to convert the light after passing through the lens barrel into image data that is indicative of the received light. The example stereoscopic visualization camera further includes a processor configured to convert the image data into stereoscopic video signals or video data for display on a display monitor.

Abstract: A method of calibrating a robotic imaging apparatus includes providing the robotic imaging apparatus, calibrating a stereoscopic camera portion of the apparatus to robot space, and registering the robot space to a patient space. An embodiment of the apparatus includes a base section defining the robot space, a robotic arm including a first end connected to the base section, a second end including a coupling interface, and a plurality of joints and links connecting the first end to the second end, each joint including a motor configured to rotate the joint around an axis and a joint sensor configured to transmit a position of the respective joint, a stereoscopic camera connected at the coupling interface, and a sensor positioned at the coupling interface and configured to detect force imparted on the stereoscopic camera by an operator and to transmit output data indicative of the detected force.

Abstract: System and method for imaging a target site with a housing assembly having a head unit configured to be at least partially directed towards the target site. An optical coherence tomography (OCT) module and stereoscopic visualization camera are at least partially located in the head unit and configured to obtain a first set and a second of volumetric data of the target site, respectively. A controller is configured to register the first set of volumetric data with the second set of volumetric data to create a third set of registered volumetric data. The third set of registered volumetric data and second set of volumetric data are rendered, via a volumetric render module, to a first and second region. The first region and the second region are overlaid to obtain a composite shared view of the target.
