Effects of blood flow on high intensity focused ultrasound ablation

2011 4th International Conference on Biomedical Engineering and Informatics (BMEI), 2011
With the benefits of high accuracy and non-invasive implementation, high intensity focused ultrasound (HIFU) is a promising medical procedure to heat and destroy pathogenic tissue rapidly. However, the relation between the power emitted by the ultrasound transducer and the energy arriving at the target area is complex, interfered by several factors ...

Noninvasive Thermometry in High-Intensity Focused Ultrasound Ablation

Ultrasound Quarterly, 2017
AbstractHigh-intensity focused ultrasound (HIFU) is emerging as an effective and promising treatment modality for the formation of coagulative necrosis inside the cancer/tumor noninvasively. To guarantee the efficacy and efficiency of HIFU ablation, the temperature field and consequent thermal dose should be monitored accurately in a high temporal and ...

High-Intensity Focused Ultrasound Ablation of Rabbit Kidney Tumors

Journal of Endourology, 1996
High-intensity focused ultrasound (HIFU) is a noninvasive surgical technique in which ultrasound energy is delivered transcutaneously to a discrete area within the body. This energy can result in a well-defined zone of cellular death within the targeted tissue. We used HIFU in an effort to ablate rabbit VX-2 kidney tumors.

High intensity focused ultrasound ablation of kidney guided by MRI

Ultrasound in Medicine & Biology, 2004
The effectiveness of magnetic resonance imaging (MRI) to monitor therapeutic protocols of high-intensity focused ultrasound (HIFU), in freshly excised pig kidney cortex is investigated. For high quality imaging, the pulse sequence fast spin echo (FSE) T1- and T2-weighted, and proton density were evaluated.

Laparoscopic Partial Kidney Ablation With High Intensity Focused Ultrasound

Journal of Urology, 2003
High intensity focused ultrasound has been performed for transrectal and extracorporeal thermal ablation of tissues. We developed and tested a laparoscopic probe that allows real-time ultrasound imaging during partial renal ablation using high intensity focused ultrasound.A Sonablate 200 (Focus Surgery, Indianapolis, Indiana) high intensity focused ...

Extracorporeal Ablation of Liver Tissue by High-Intensity Focused Ultrasound

Oncology, 2009
High-intensity focused ultrasound (HIFU) may produce a well-delineated lesion of coagulation necrosis in deep organs, by means of an extracorporeal transducer. Applications of this method to the liver in animal models have been studied for many years. The effects of HIFU on the normal liver parenchyma and on hepatic tumors are reviewed.

Liver Cancer Ablation with Extracorporeal High-Intensity Focused Ultrasound

European Urology, 1993
Recent animal studies have demonstrated the capacity of high-intensity focused ultrasound (HIFU) to extracorporeally ablate selective tissue targets in the liver without requiring surgical exposure of the liver or insertion of instruments into the liver.

High-intensity focused ultrasound ablation of uterine localized adenomyosis

Current Opinion in Obstetrics & Gynecology, 2010
To introduce recent developments in a noninvasive treatment of using high-intensity focused ultrasound (HIFU) for ablating uterine localized adenomyosis, and to discuss their potential in this application.This literature roughly reviewed conservative therapy for uterine localized adenomyosis and emphasized using HIFU for ablating it.

High-intensity focused ultrasound ablation of muscle in an anticoagulated swine model

Minimally Invasive Therapy & Allied Technologies, 2020
Image-guided non-invasive high-intensity focused ultrasound (HIFU) has been gaining recognition in treating musculoskeletal tumors and desmoids. However, there is no consensus on the appropriate perioperative management for patients on ongoing anticoagulation who undergo HIFU ablation.Image-guided HIFU treatment was performed in swine on an ongoing ...
