Input data acquired with respect to a part of a patient is received by the system. The part corresponds to an organ, e.g., lung, of the patient to be operated on and includes one or more lesions to be removed during an operation.

Based on the generated anatomic 3D model, a preoperative plan for linear-cutting stapler resection of the one or more lesions from the organ to be carried out during the operation is obtained.

Abstract: During a sEEG (stereo-electroencephalography) intervention into the skull of a patient, there is requirement to drill a large number of trajectories. Typically, instrument stabilisation platforms and robots for protocols requiring only one or two trajectories are rigidly fixed to the skull using surgical anchor members fixed into the skull around the one or two trajectories. However, because sEEG interventions require a large number of trajectories, an impractical number of surgical anchor members need to be fixed into the skull resulting in patient discomfort. Attachment of an intervention platform to all surgical anchor members is not required at once. Accordingly, it is proposed to search for intersection points of the maximum extent of an intervention platform between at least two trajectory entry points on an object of interest of patient, so that at least one surgical anchor member can be shared when the intersection point is at first and the second trajectories.

An augmented reality overlay (e.g. computer generated images) is rendered and displayed over images of a tracked anatomical structure. An optical sensor unit provides tracking images of targets associated with objects including the anatomical structure in a real 3D space as well as visible images thereof. The anatomical structure is registered, generating corresponding poses of the anatomical structure in a computational 3D space from poses in the real 3D space. The overlay pose in the computational 3D space is aligned with the anatomical structure pose so that the overlay is rendered on a display of the anatomical structure in a desired pose. The overlay may be generated from a (3D) overlay model such of a generic or patient specific bone, or other anatomical structure or object. The overlay may be used to register the anatomical structure.

Some implementations may include optical fiducials integrated with a patient tracking assembly to aid in tracking the patient and determining perspective of the HMD.
