Abstract

Medical technologies have undergone significant development to overcome the problems inherent in Minimally Invasive Surgery (MIS) such as inhibited manual dexterity, reduced visual information and lack of direct touch feedback to make it easier for surgeons to operate. An endoscopic tool incorporating haptic feedback is being developed to increase the effectiveness of diagnostic procedures by providing force feedback. Magnetic Resonance Imaging (MRI) guidance is possible to allow tool localisation, however this enforces the requirement of MR compatibility on the device. This paper describes the work done in developing MR compatible sensing devices using piezoelectric sensor elements in two different formats and how each can be used to locate subsurface inclusions in s mined oft substrates. Results show that the position of a hard inclusion can be deterwith both methods.
