ABSTRACT In recent years, High Intensity Focused Ultrasound (HIFU) has emerged as a non-invasive surgical modality and also through understanding of the physical principles in the interactions of HIFU with biological tissue in parallel with the progress in transducer technology, the development towards the adoption of HIFU approach promising in permitting contact-free in-depth tissue accessible for ultrasound. In addition to that, robotic techniques are looked into to provide complex maneuver that can achieve the objectives of precise and accurate mechanical manipulations in various configurations. With robot assistance into the surgical arena, it allows surgeon to work with greater accuracy. A interaction robotic with HIFU system will provide great feasibility for surgery dealing with brain tumours. The aim of this project is to understand the existing design of water bolus and base unit. Thereafter design an integrated interface unit for water bolus with base unit, which will be used in brain tumour treatments. Design procedures such as function analysis, morphological chart are used. Conceptual designs were generated and configurations were discussed. The selections of designs were based on analytical evaluations of various designs. Calculation of critical areas was done. Simulation and selection of parts were involved to determine the feasibility of the design. Testing was carried out for the prototype using Galil Controller and thus achieved the objective.
