Abstract
A surgical assistance method can include: generating a 3D representation of a set of anatomical structures, registering the 3D representation with a subject, displaying an overlay of the 3D representation, determining a trajectory, determining surgical guides, determining observation parameters, and/or facilitating the surgical procedure. The method functions to generate a virtual cut displayed on a 3D representation of a subject to facilitate provider planning and/or performance of a surgical incision.
Claims20
A method for displaying surgical information, comprising:
- determining a 3D model of a patient generated based on a set of computed tomography (CT) scans of the patient, wherein the 3D model comprises an internal virtual structure;
- identifying a plurality of mapping points in the 3D model;
- receiving a measurement of the patient captured using a sensor;
- registering the 3D model with the measurement by matching a set of features within the measurement with mapping points from the plurality of mapping points;
- determining a trajectory which intersects a first endpoint on the internal virtual structure and intersects a second endpoint proximal to a surface of the patient;
- generating a volumetric view section based on the internal virtual structure and the trajectory, wherein:
- a dimension of the volumetric view section is based on a dimension of the internal virtual structure;
- and
- the volumetric view section spans the first endpoint and the second endpoint;
- selecting a set of virtual structures from the 3D model which intersect the volumetric view section;
- and
- in a display, overlaying a representation of the selected set of virtual structures and a representation of the trajectory onto the measurement based on the 3D model registration.
A method, comprising:
- receiving a 3D model of a patient generated using a set of cross-sectional scans of the patient, wherein the 3D model comprises a target structure;
- identifying a plurality of mapping points in the 3D model;
- and
- iteratively:
- determining a measurement of the patient using a sensor;
- registering the 3D model with the measurement by matching a set of features within the measurement with the plurality of mapping points;
- and
- in an extended reality headset, overlaying, onto the measurement based on the registration:
- a volumetric path, determined based on the target structure, that extends from the target structure to the second point along a trajectory;
- and
- a set of virtual structures from the 3D model, wherein virtual structure inclusion in the set of virtual structures is based on an intersection of the respective virtual structure with a volumetric view section surrounding the volumetric path.
