1. A method of sizing a surgical implant to an anatomical feature characterized in part by a missing or malformed portion in a cranioplasty, the method comprising:
generating at least one computer-readable reconstruction of the anatomical feature with a source, wherein the at least one computer-readable reconstruction of the anatomical feature includes position information corresponding to an orientation of the source, wherein the being's anatomy comprises a skull;
accessing the at least one computer-readable reconstruction of the being's anatomy and position information;
displaying an image based on the at least one computer-readable reconstruction of the anatomical feature and the position information; and
projecting the image onto a surface of the surgical implant, wherein a surgeon traces the image with a sterile marking pen directly onto the surface of the surgical implant to outline projected points of the anatomical feature in the image onto corresponding physical locations on the surface of the surgical implant, and wherein the projecting is performed using a projector device.
