Abstract: The invention comprises a system and method that may help place or position a component, such as an acetabular cup or a femoral component, during surgery. An example system may iteratively register a plurality of two-dimensional projections from a three-dimensional model of a portion of a patient, the three-dimensional model being generated from a data set of imaging information obtained at a neutral position. An example system may further score each two-dimensional projection against an intra-operative image by calculating a spatial difference between corresponding points. A two-dimensional projection having a minimum score reflecting the smallest distance between the corresponding points may be identified.

Abstract: The present disclosure is directed toward systems and methods for generating a composite radiographic image that corrects effects of parallax distortion. A sequence of radiographic images—including a series of discrete exposures or image frames from a fluoroscopic procedure—may be acquired using a C-arm apparatus. An exemplary method may include receiving a plurality of radiographic image frames pertaining to a patient, identifying a region of interest on the image frames, cropping the region of interest from a plurality of image frames, selecting a plurality of sequential portions of cropped image frames, and stitching together the selected portions to form a composite image that corrects effects of parallax distortion and displaying a three-dimensional image of a part of the patient according to the orientation of the patient calculated from this two-dimensional intra-operative radiographic imaging information.

Abstract: A computerized visual orientation surgery assist system and method receives initial anatomic image information of a patient scan, which may be taken at a registration position of the patient; receives initial surgical instrument positional information from a first positional sensor positioned on a surgical instrument, where the positional sensor senses three-dimensional spatial position transmits the surgical instrument positional information; establishes the initial surgical instrument positional information as a surgical instrument origin in three-dimensional space for the initial anatomic image information; displays a visual representation of the initial anatomic image information on a computerized display, the visual representation including a surgical instrument representation based on the initial surgical instrument positional information; receives subsequent surgical instrument positional information from the first sensor associated with movement of the surgical instrument; and updates the computerized

Abstract: A computerized visual orientation surgery assist system and method receives initial anatomic image information of a patient scan taken at a registration position of the patient; receives initial positional information from a sensor positioned on the patient at a registration position, where the positional sensor senses spatial position in three dimensions and transmits the positional information; establishes the initial positional information as an origin in three-dimensional space for the initial anatomic image information; displays a visual representation of the initial anatomic image information on a computerized display; receives subsequent positional information from the sensor associated with movement of the patient; and updates the computerized display to reflect the subsequent positional information with respect to the initial positional information.

Abstract: A surgical method and workflow to improve the efficiency of a surgical procedure by intraoperatively acquiring a digital radiographic image, processing the digital radiographic image, and using information based on the radiographic image to make adjustments during the surgical procedure. A checklist of parameters may be displayed so that the surgeon can confirm all considerations have been made for the surgical procedure.
