Hemostasis using high intensity focused ultrasound

European Journal of Ultrasound, 1999
High intensity focused ultrasound (HIFU) has been shown to be an effective method of hemostasis, in animal studies, for both solid organs and blood vessels. Two distinct effects of HIFU, thermal and mechanical, appear to contribute to hemostasis. Acoustic hemostasis may provide an effective method in surgery and prehospital settings for treating trauma

High-intensity focused ultrasound therapy

Best Practice & Research Clinical Obstetrics & Gynaecology, 2018
High-intensity focused ultrasound therapy has received increasing interest in the management of benign uterine tumors. Either magnetic resonance or ultrasound imaging has been used to target and monitor the ablation process. This article provides an overview of the background, clinical use, treatment outcomes, and safety of high-intensity focused ...

High-intensity focused ultrasound for prostate cancer

Expert Review of Medical Devices, 2020
High-intensity focused ultrasound (HIFU) is a noninvasive procedure that has shown promising results in a wide range of malignant and nonmalignant conditions, including localized prostate cancer (PCa). This review aims to describe the application of HIFU in the management of patients with PCa, explaining its basic therapeutic principles, going through ...

High-Intensity Focused Ultrasound

2017
High-intensity focused ultrasound (HIFU) is an effective noninvasive procedure for the focal treatment of prostate cancer (PCa). The possibility of inducing precise coagulative necrosis of the tumor with sharp boundaries makes HIFU one of the best options for focal therapy.

High-intensity Focused Ultrasound: Ready for Primetime

Urologic Clinics of North America, 2010
Prostate cancer (CaP) is the second most common cause of cancer deaths in the United States and the incidence of CaP has remained constant at 165 cases per 100,000 men. Since 1990, the age-adjusted death rate has decreased by 31%. In this article, the authors review the current literature on the experimental therapy for HIFU.

High-Intensity Focused Ultrasound (HIFU)

High-Intensity Focused Ultrasound (HIFU) is a medical technology that uses ultrasound waves to deliver focused energy at a specific target within the body. This non-invasive technique has gained recognition for its potential in various therapeutic applications. The principle behind HIFU involves using an ultrasound transducer to generate high-frequency

pMUT for high intensity focused ultrasound

2012 IEEE International Ultrasonics Symposium, 2012
Capacitive ultrasonic tranducers, cMUTs rely on the electrostatic field between the membrane and a back plate for sensing andactuation. This is an excellent solution for small amplitudes. But the movement of the membrane is physically limited by the bottom plate (risk of collapse).

Ultrasound imaging for high intensity focused ultrasound therapy

The Journal of the Acoustical Society of America, 2005
We have investigated the use of ultrasound-based imaging to develop a non-invasive, safe and real-time method of guidance and monitoring for HIFU therapy. HIFU application was synchronized with the imaging frame rate to allow interference-free visualization of the region of interest.

[High-intensity focused ultrasound transducer].

Sheng wu yi xue gong cheng xue za zhi = Journal of biomedical engineering = Shengwu yixue gongchengxue zazhi, 2011
High-intensity focused ultrasound (HIFU) has been used to precisely ablate a targeted area within the body without harming the overlying tissues. In recent years, HIFU, as a noninvasive, effective and feasible modality, has been used for cancer therapy. The development of HIFU transducer is the key technology of HIFU. This paper shows the acoustic lens

Focal High-Intensity Focused Ultrasound (HIFU)

2014
Transrectal high-intensity focused ultrasound (HIFU) is highly suitable for focal therapy of localized prostate cancer for several reasons. HIFU induces immediate and irreversible coagulative necrosis with sharply delineated boundaries. The treatment can be accurately targeted to a portion of the prostate gland.
