Ultrasound 3D positioning system for surgical instruments

This thesis presents various aspects regarding the development of an ultrasound sensor systems for use in laparoscopic intervention. The accuracy achieved after using compensation technique for air flow disturbances or temperature variations remains in a convenient range of 200um. Considering this high accuracy, the flexibility and the ergonomics achieved for this system, the final device may be adapted very easily and used also in other microsurgery applications.
