Characterization Methods of High-Intensity Focused Ultrasound-Induced Thermal Field

High-intensity focused ultrasound (HIFU) is a minimally invasive medical procedure which has shown considerable potential for a variety of therapeu­ tic applications. Some of the medical applications of HIFU include thermal ablation of tumors and uterine fibroids, vessel cauterization, thrombolysis, drug delivery, and gene activation (Curra and Crum [1]). HIFU ablation, unlike other minimally i...

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 ...

Numerical Study for Optimizing Parameters of High-Intensity Focused Ultrasound-Induced Thermal Field during Liver Tumor Ablation: HIFU Simulator

Introduction High intensity focused ultrasound (HIFU) is considered a noninvasive and effective technique for tumor ablation. Frequency and acoustic power are the most effective parameters for temperature distribution and the extent of tissue damage. The aim of this study was to optimize the operating transducer parameters such as frequency and input power in order to acquire suitable temperatu...
