Abstract: Methods and systems are presented herein for augmented reality assisted surgery. Methods and systems include methods and systems for using physical registration objects with a known geometry for registration to determine a reference coordinate system for an augmented reality scene for a surgical setting. Methods and systems include methods and systems for providing an integrated virtual workbench for presenting and sharing patient data in a surgical setting. Methods and systems include methods and systems for providing augmented reality guidance for plate bending for craniomaxillofacial implant surgery.

Abstract: Certain aspects of the present disclosure provide for a method of determining a virtual occlusion. The method may include obtaining a 3-D representation of a patient's first and second jaw portions. The method may further include, with the 3-D representation, representing in a GUI an initial position of the first jaw portion relative to the second jaw portion, the initial position being defined by six pre-determined degrees of freedom relative to a coordinate system fixed relative to the first jaw portion. The method may further include receiving user input of changes at least one degree of freedom, and automatically adjusting at least one other degree of freedom to minimize a vertical distance of the control point to the origin, thereby determining a virtual occlusion. The method may further include representing, in the GUI, the first and second jaw portions in the determined virtual occlusion.

Abstract: Certain embodiments provide a system for calibrating an X-ray image. The system may receive an X-ray image of an anatomical part of a patient. The system may further receive a 3-D surface scan of a surface of the patient where the anatomical part is located. The system may derive a measurement correction to apply to measurements of the X-ray image based on the 3-D surface scan. The measurement correction may account for: an orientation of the patient with respect to the X-ray detector plate, a first distance between the patient and the detector plate, or a second distance between the patient and an X-ray source used to generate the X-ray image. The system may further determine a corrected measurement of the anatomical part based on the measurement correction and a measurement taken from the X-ray image.

Abstract: Systems and methods of radiograph correction and visualization are disclosed. Certain embodiments provide a method for generating a 3D model of at least part of one anatomical object based on one or more radiographs. The method further includes positioning the 3D model based on information indicative of a normalized projection comprising information indicative of a desired position and orientation of the at least part of one anatomical object with respect to the projection plane. The method further includes generating a 2D projection of the 3D model onto the projection plane. The method further includes generating one or more modified radiographs of the at least part of one anatomical object based on the 2D projection.
