Abstract:
1. In a computerized device, a method comprising: displaying, on a graphical user interface, an image of an anatomical structure; identifying, via an input device on the graphical user interface, a set of landmark locations identifying respective anatomical positions within the displayed image of the anatomical structure; displaying a graphical overlay over the image of the anatomical structure, placement of the graphical overlay based on the set of landmark locations; and displaying at least one localization marker within the graphical overlay, the at least one localization marker identifying a location for performing a surgical operation associated with the anatomical structure; wherein displaying an image of an anatomical structure comprises displaying an image of the anatomical structure, the image including an image of at least one bone; wherein identifying a set of landmark locations comprises receiving a structure selection of a specific anatomical structure to which landmark locations are to be provided, the structure selection defining a number of landmark locations to be identified; receiving a selection, via a graphical pointer on the graphical user interface, of a first known bone location and a second known bone location associated with the at least one bone; and wherein displaying a graphical overlay over the image of the anatomical structure comprises rendering the graphical overlay between the selected first known bone location and the selected second known bone location, the graphical overlay including a series of guidance indicators operable to indicate positions associated to the anatomical structure for performing the surgical operation associated with the anatomical structure; wherein displaying an image of the anatomical structure comprises displaying, on the graphical user interface, an image of a knee joint including a graphical view of a femur and tibia; and wherein displaying a graphical overlay over the image of the anatomical structure comprises displaying the graphical overlay over the view of at least one of the femur and the tibia within the image, the graphical overlay enabling ease of determination of at least one reference location to be marked by the at least one localization marker for performing a surgical operation related to repair of a ligament of the human knee joint; wherein displaying an image showing a view of a femur and tibia within a human knee joint comprises displaying a lateral view of the femur within a human knee joint; wherein receiving a selection of first and second known bone locations comprises receiving, as the first known bone location, a selection of an anterior edge of the view of the femur displayed within the image; receiving, as the second known bone location, a selection of a posterior edge of the view of the femur displayed laterally within the image, a line defined between the first known bone location and the second known bone location defining a plane that substantially aligns with a patellar surface of the femur; and wherein the method comprises receiving a selection of a third known bone location corresponding to the laterally displayed distal condyle surface of the femur within the image; and wherein displaying a graphical overlay over the image of the anatomical structure comprises displaying an overlay grid over the view of the distal end of the femur within the graphical user interface, the overlay grid having a width rendered between the selected first and second known bone locations, and having a height that extends to the selected third known bone location.
