Non-Invasive Prostate Tissue Ablation –Ā The Focal OneĀ® HIFU Robotic System uses high performance, high intensity focused ultrasound (HIFU) technology that allows for precise targeting and destruction of part of the prostate, sparing healthy surrounding tissue and minimizing side effects. By focusing high-intensity ultrasound waves on the affected area, causing localized heating that destroys the cells in the gland without damaging the healthy surrounding tissue. Focused ultrasound works in the same way as rays of sunlight that pass through a magnifying glass and are concentrated at a single point, causing a significant temperature rise around the focal point.
