Use of high-intensity focused ultrasound to control bleeding

High-Intensity Focused Ultrasound –

High intensity focused ultrasound (HIFU).

INTRODUCTION Curative treatments for localized prostate cancer, from least invasive to most invasive, include brachytherapy, cryosurgery, three-dimensional conformal radiation therapy, external beam radiation therapy, and radical prostatectomy. A patient with localized, low risk or intermediate risk prostate cancer who is diagnosed at an early age and receives one of these treatments has only a...

Thermography in High-Intensity Focused Ultrasound Ablation

Application of high-intensity focused ultrasound (HIFU) in therapeutic medicine has started in the 1950s for the treatment of Parkinson’s disease. With the development of medical diagnosis, such as ultrasound imaging and magnetic resonance imaging (MRI), automatic control, imaging processing and electrical technology, extracorporeal and intrarectal HIFU systems have been developed for clinical ...

Laparoscopic High Intensity Focused Ultrasound: Application to Kidney Ablation

This work demonstrates the feasibility of using high intensity focused ultrasound (HIFU) for selective ablation of renal tissue through laparoscopic procedures. Two laparoscopic HIFU probe prototypes were developed and tested. Probe 1: It is a hand-held probe with no integrated ultrasound imaging capability. It consists of two focused rectangular HIFU piezoceramic crystals mounted on a stainles...
