HIFU (High Intensity Focused Ultrasound ) Ceramics

Introduction

High intensity focused ultrasound (HIFU) is a medical procedure that applies high intensity focused ultrasound energy to locally heat and destroy diseased or damaged tissue through ablation.

Medical uses:
Therapeutic applications use ultrasound to bring heat or agitation into the body; much higher energies are used than in diagnostic ultrasound. In many cases the frequencies used are different.

  • Ultrasound sources may be used to generate regional heating and mechanical changes in biological tissue, e.g. in occupational therapy, physical therapy and cancer treatment. However the use of ultrasound in the treatment of musculoskeletal conditions has fallen out of favor.
  • Focused ultrasound may be used to generate highly localized heating to treat cysts and tumors (benign or malignant), This is known as Magnetic Resonance guided Focused Ultrasound or High Intensity Focused Ultrasound (HIFU). These procedures generally use lower frequencies than medical diagnostic ultrasound (from 0.250 to 2 MHz), but significantly higher energies. HIFU treatment is often guided by MRI.
  • Focused ultrasound may be used to break up kidney stones by lithotripsy.
    Ultrasound may be used for cataract treatment by phacoemulsification.
  • Low-intensity ultrasound has been found to have physiological effects such as ability to stimulate bone-growth, and potential to temporarily disrupt the blood–brain barrier for drug delivery.
  • Procoagulant at 5–12 MHz
