AUGMENTED-REALITY SURGICAL SYSTEM USING DEPTH SENSING

Disclosed herein are systems, devices, and methods for image-guided surgery. Some systems include a head-mounted unit, having a see-through augmented-reality display and a depth sensor, which is configured to generate depth data with respect to a region of interest (ROI) of a body of a patient that is viewed through the display by a user wearing the head-mounted unit. A processor, which is configured to receive a three-dimensional (3D) tomographic image of the body of the patient, computes a depth map of the ROI based on the depth data generated by the depth sensor, to compute a transformation over the ROI so as to register the tomographic image with the depth map, and to apply the transformation in presenting a part of the tomographic image on the display in registration with the ROI viewed through the display.

SYSTEM AND METHOD FOR GENERATING PARTIAL SURFACE FROM VOLUMETRIC DATA FOR REGISTRATION TO SURFACE TOPOLOGY IMAGE DATA

The present disclosure relates to the generation of partial surface models from volumetric datasets for subsequent registration of such partial surface models to surface topology datasets. Specifically, given an object that is imaged using surface topology imaging and another volumetric modality, the volumetric dataset is processed in combination with an approach viewpoint to generate one or more partial surfaces of the object that will be visible to the surface topology imaging system. This procedure can eliminate internal structures from the surfaces generated from volumetric datasets, thus increases the similarity of the dataset between the two different modalities, enabling improved and quicker registration.
