OBJECTIVE The purpose of this paper is to explore the feasibility of developing a MRI-compatible needle driver system for radiofrequency ablation (RFA) of breast tumors under continuous MRI imaging while being teleoperated by a haptic feedback device from outside the scanning room. The developed needle driver prototype was designed and tested for both tumor(More)
Rats were given two free unrewarded trials per day in different T-mazes, oriented at 90 degrees to each other, and wiped with either Cajuput or Anise, which produced distinctive odours. The rate of spontaneous alternation was 82.8 per cent when the same odour was present on both trials, 62.5 per cent when the odour was changed between trials. This result(More)
Magnetic Resonance Imaging (MRI) is superior to other imaging modalities such as Ultrasound and Computed Tomography and is used for both diagnostic and therapeutic procedures. However, current breast biopsy procedures based on MR images obtained apriori, use a blind targeting approach, which can be long and painful. Current approaches, due to possible(More)
