Abstract

Nowadays, the interest to use ultrasound waves in medical field is well established. Such ultrasound waves may be focused for treating a zone in an organ such as the brain for instance. The focus allows to treat only the zone relative to the disease and avoid treating a healthy zone. Therefore, it is mandatory to use an image guidance system to monitor in real time where the ultrasound waves are focused. The guidance can be performed by Magnetic Resonance Imaging (MRI), Ultrasound Imaging (echography), or Optical Imaging (neuronavigation). However, such systems increase the cost and the complexity of the whole process. The present disclosure overcomes the above drawbacks by proposing a self-positioning acoustic lens allowing to ensure good ultrasound waves transmission in the zone to treat without requiring to the use of a navigation system.
