|The Computer System for the Image Guided Surgery works on visual recognition of the instruments by two infra-red cameras. These cameras identify the position of the instruments and generate accurate 3 dimensional image of the knee on the computer screen. The surgeon can then rotate the image to find out correct orientation and apply the cutting instruments.
Once an accurate image is generated, the surgeon is able to see how a knee replacement would look like and behave
before doing anything to the bones. This simulation is invaluable in judging the size of the implants and pre-empting any
difficulties possible during the surgery.
