HIFU (High-Intensity Focused Ultrasound) sometimes FUS or MIFUS is a highly precise medical procedure using high-intensity focused ultrasound to heat and destroy pathogenic tissue rapidly in the brain for neurosurgical purposes, by causing coagulation necrosis. Here we have described a system that uses specially designed micro-transducer heads that are placed inside the later ventricles for the purposes of MIFUS lesioning of brain targets under real time MRI, endoscopic and Doppler guidance. A minimally invasive approach using Kochers point allows small incisions with little bleeding, recovery time, infection risk and surgical time. This approach allows insertion of the micro-ultrasound transducers into the lateral ventricles of the brain avoiding skull bone attenuation of the ultrasonic waves and unnecessary heating of brain tissues in the process.
