A computer (12) determines the virtual position of models of anatomical structures and a surgical tool, based on the detected positions of the anatomical structure and the tool. A display device (18) connected to the computer is controlled to display models of the anatomical structure and the tool at their respective virtual positions. A three-dimensional model of the anatomical structure is displayed such that it appears as partially transparent. A position setting system (22) registers the position of the surgical tool and the anatomical structure, and transmits the positional information to the computer. A storage device (14), such as a disc drive, a CD-ROM drive, a hard-disc drive or a computer memory, is connected to the computer, to store the models of anatomical structure and surgical tool. Independent claims are also included for the following: (a) an interactive interface for the computer system; (b) a method to assist a surgical procedure using the system; (c) a method of determining the position of a surgical implant on at least one anatomical structure. |
