Systems and methods for surgical guidance and image registration are provided, in which three-dimensional image data associated with an object or patient is registered to topological image data obtained using a surface topology imaging device. The surface topology imaging device may be rigidly attached to an optical position measurement system that also tracks fiducial markers on a movable instrument. The instrument may be registered to the topological image data, such that the topological image data and the movable instrument are registered to the three-dimensional image data. The three-dimensional image data may be CT or MRI data associated with a patient. The system may also co-register images pertaining to a surgical plan with the three-dimensional image data. In another aspect, the surface topology imaging device may be configured to directly track fiducial markers on a movable instrument. The fiducial markers may be tracked according to surface texture.

System and methods for intraoperative guidance feedback

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.

System and method for generating partial surface from volumetric data for registration to surface topology image data

Systems and methods are provided for optical topology detection and illumination. Embodiments provide an integrated system, and methods of operation thereof, where the integrated system includes an illumination system and an optical topology detection system, and where at least a portion of the spectral content of illumination light from the illumination system is within an optical detection bandwidth of the optical topology detection system, and where the operation of the optical topology detection system and the illumination system are interleaved to avoid crosstalk, such that the optical topology detection system detects the optical topology detection light when the illumination system is not emitting illumination light. The system may include, and control the operation of, an optical navigation system. The components of the system may be mounted to a rigid frame to maintain calibration.
