Systems, methods and devices are disclosed for use in electronic guidance systems for surgical navigation to determine the relationship between the three-dimensional coordinates of an anatomy of a patient and those of medical image data. These coordinates are required to assist in the determination of the surgical measurements with respect to which components, such as, an acetabular prosthesis, are inserted into a body of the patient, hi one example, during hip replacement surgery, a surgeon receives guidance of how to place an acetabular prosthesis in the body of the patient specifically in the pelvis with respect to medical image data.
