Optical mouse sensors for tracking surgical instruments

The computer mouse is a popular pointing device used to control the position of a cursor on a computer display. Sensors used in optical mice enable the contactless measuring of the changes in position over a flat surface.This article describes the application of optical mouse sensors as position sensors in a tracking system – TrEndo – that has been developed at Delft University of Technology and the Academic Medical Centre Amsterdam.
