Description of a method: computer generated virtual model for accurate localisation of tumour margins, standardised resection, and planning of radiation treatment in head & neck cancer surgery.

Communication between the surgeon, the pathologist and the radiation oncologist is improved by a virtual model of the final resection combining 3D imaging with computer aided navigation. The pathologist localises any questionable margins and the oncologist plans focussed delivery of radiation to native tissue in an area of complex anatomy.
