Resection of Abdominal Solid Organs Using High-Intensity Focused Ultrasound

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...

Characterization of high intensity focused ultrasound transducers using acoustic streaming.

A new approach for characterizing high intensity focused ultrasound (HIFU) transducers is presented. The technique is based upon the acoustic streaming field generated by absorption of the HIFU beam in a liquid medium. The streaming field is quantified using digital particle image velocimetry, and a numerical algorithm is employed to compute the acoustic intensity field giving rise to the obser...

Noninvasive Treatment of Breast Cancer Using High-Intensity Focused Ultrasound

Breast conserving surgery is a standard procedure for breast cancer since 1970. Now noninvasive therapy with few complications is preferred. High-intensity focused ultrasound (HIFU) has been developed to ablate solid tumor or cancer noninvasively. Its clinical outcome on breast cancer in China and Europe as well as the induced vascular destruction and immune response are summarized. In summary,...

Treatment of localised prostate cancer using high-intensity focused ultrasound.

OBJECTIVE To evaluate the biochemical disease-free survival (DFS), predictors of clinical outcome and morbidity of patients with localized prostate cancer treated with high-intensity focused ultrasound (HIFU), a noninvasive treatment that induces complete coagulative necrosis of a tumour at depth through the intact skin. PATIENTS AND METHODS In all, 63 patients with stage T1c-2bN0M0 localized...
