High-Intensity Focused Ultrasound (HIFU) HIFU is highly precise medical procedure using high-intensity focused ultrasound to heat and destroy pathogenic tissue rapidly. Clinical HIFU procedures are typically image-guided to permit treatment planning and targeting before applying a therapeutic or ablative level of ultrasound energy...[more]

Stereotactic surgery The stereotactic method was first developed by two British scientists in 1908, working at University College London Hospital. The apparatus they developed was used for animal experimentation and implemented a Cartesian (three-orthogonal axis) system. Improved designs of their original device came into use in the 1930s and are still in wide use today...[more]

The Harmonic Scalpel A harmonic scalpel is a piece of medical equipment used in surgical procedures as an option to a steel scalpel or electro-surgical diathermy. It uses ultrasound technology to cut tissues while simultaneously sealing the edges of the cut. The system typically is composed of a hand-held ultrasonic transducer, generator, hand switch....[more]
