What is Sonablate® HIFU?

With high-intensity focused ultrasound, or HIFU, we can target and destroy damaged prostate tissue without affecting the surrounding healthy tissue.
We use Sonablate®️ technology.

How does Sonablate® HIFU work?

High-intensity focused ultrasound, or “HIFU,” uses sound energy to generate heat that ablates (destroys) targeted tissue within the body. The concept is similar to using the sun and a magnifying glass to burn a hole in a leaf. Focused sound waves pass safely through prostate tissue until they reach the focal point, where they produce enough heat to destroy only that tissue.

Step 1: Plan

Based on MRI results and your individual needs, your physician will create a treatment plan for tissue that needs to be ablated (destroyed).

Step 2: Ablate

With pinpoint accuracy, Sonablate HIFU will ablate only the diseased tissue, leaving healthy tissue unharmed. 

Step 3: Monitor and Adjust

Your physician will monitor the procedure in real-time, adjusting and customizing the procedure to address your individual condition.
