Computer software which takes information from a medical imaging modality and generates an automated overlay of the patient's internal anatomy, correlating the image to the location of the patient's actual body part during surgery; computer software for the use informatics, being the science of processing data for storage and retrieval, allowing for the manipulation of digital images as image data sets and relevant mathematical calculations to determine physical dimensions such as volume, distance; integrated treatment planning and delivery systems comprised of computer hardware and computer software which generate images allowing surgeons to plan surgery on a computer workstation and then perform the surgery using these images; computer hardware and computer software generating two-dimensional and three-dimensional images from medical imaging modalities such as magnetic resonance imaging, computer tomography, scanners and x-rays which can be viewed, stored, manipulated, measured and sent electronically to other computers used for diagnostic and surgical purposes; computer hardware and computer voice recognition software allowing for oral reports to generated and attached to electronic images

optical tracking systems comprised of infra-red cameras which detect light emitting diodes mounted on pointers or surgical instruments which interface with medical imaging computer software in order to determine the position of surgical instruments during medical operations
