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.

Abstract: A system, method, and apparatus for displaying a fused reconstructed image with a multidimensional image are disclosed. An example imaging system receives a selection corresponding to a portion of a displayed multidimensional visualization of a surgical site. At the selected portion of the multidimensional visualization, the imaging system displays a portion of a three-dimensional image which corresponds to the selected multidimensional visualization such that the displayed portion of the at least one of the three-dimensional image or model is fused with the displayed multidimensional visualization.

Abstract: A robotic imaging apparatus is disclosed. A robotic imaging apparatus includes a robotic arm, a stereoscopic camera, and a sensor positioned between the robotic arm and the stereoscopic camera. The sensor transmits output data that is indicative of translational and/or rotational force imparted on the stereoscopic camera by an operator. The robotic imaging apparatus also includes a processor that is configured to determine a movement sequence for the robotic arm based on a current position of the robotic arm and the output data from the sensor and to cause at least one of the joints of the robotic arm to rotate based on the determined movement sequence via one or more motor control signals provided to the at least one joint. The rotation of the at least one joint provides power-assisted movement of the robotic arm based on the detected translational and/or rotational forces imparted by the operator.
