Abstract:

A method for computer-assisted planning of a transplant surgery is provided. The method includes obtaining a computer-readable representation of a donor and recipient skeletal fragment; determining surgical cutting planes on the computer-readable representation of the donor skeletal fragment from which a portion of the donor skeletal fragment from the computer-readable representation of the donor skeletal fragment will be harvested; determining virtual cutting guides; performing a virtual osteotomy to separate the portion of the donor skeletal fragment from the computer-readable representation of the donor skeletal fragment from a remainder portion of the donor skeletal fragment based on a position of the virtual cutting guides that are attached to the computer-readable representation of the donor skeletal fragment; positioning the donor skeletal fragment within a transplant region of the recipient skeletal fragment; and creating a hybrid computer-readable representation comprising the recipient skeletal fragment and the portion of the donor skeletal.

Abstract:

A computer-assisted surgical system can include a donor sub-system and a recipient sub-system. The donor sub-system includes a first reference unit having a first trackable element, a fragment reference unit having a second trackable element, and a first detector configured to provide at least one of a first signal corresponding to a detected location of one or more of the first trackable element and the second trackable element. The recipient sub-system includes a second reference unit having a third trackable element, and a second detector configured to provide at least one of a second signal corresponding to a detected location of at least the third trackable element.

Abstract:

Apparatuses, systems, and methods for object recognition and presentation are provided. An example apparatus may include a camera, an assistance feedback device, an input device, and processing circuitry. The processing circuitry may be configured receive an image from the camera, compare characteristic features within the image to an object identification dataset to identify object matches for a plurality of objects within the image, receive a selected name of an identified object from the user via the input device, and transmit assistance feedback to the user indicating a position of the selected object within the field of view via the assistance feedback device.

G06T 7/00

Abstract:

An apparatus for improving performance of a retinal implant may include processing circuitry. The processing circuitry may be configured to receive image data corresponding to a camera field of view, determine whether a particular object is detected within the camera field of view, perform image data processing to enable a representation of a portion of the image data corresponding to an implant field of view to be provided on a retinal implant where the implant field of view is smaller than the camera field of view, and, responsive to the particular object being located outside the implant field of view, provide a directional indicator in the implant field of view to indicate a location of the particular object relative to the implant field of view.
