High Intensity Focused Ultrasound (HIFU) Ablation

2012
The ideal cancer therapy not only induces the death of all localized tumor cells without damage to surrounding normal tissue, but also activates a systemic antitumor immunity. High intensity focused ultrasound (HIFU) has the potential to be such a treatment, as it can non-invasively ablate a targeted tumor below the skin surface, and may subsequently ...

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.

High intensity focused ultrasound ablation and antitumor immune response

The Journal of the Acoustical Society of America, 2013
The ideal cancer therapy not only induces the death of all localized tumor cells without damage to surrounding normal tissue, but also activates a systemic antitumor immunity. High intensity focused ultrasound (HIFU) has the potential to be such a treatment, as it can non-invasively ablate a targeted tumor below the skin surface, and may subsequently ...

Multiple High-Intensity Focused Ultrasound Probes for Kidney-Tissue Ablation

Journal of Endourology, 2005
To investigate kidney-tissue ablation by high-intensity focused ultrasound (HIFU) using multiple and single probes.Ultrasound beams (1.75 MHz) produced by a piezoceramic element (focal distance 80 mm) were focused at the center of renal parenchyma.

Extracorporeal Liver Ablation Using Sonography-Guided High-Intensity Focused Ultrasound

Investigative Radiology, 1992
High-intensity focused ultrasound (HIFU) is the only radiation beam that can remotely destroy deep-seated tissue targets without causing damage to the intervening tissues. This study evaluates the ability of sonography-guided HIFU to extracorporeally induce liver ablation in a rabbit model.Under sonographic guidance, the HIFU beam was transcutaneously ...

Extracorporeal Ablation of Liver Tissue by High-Intensity Focused Ultrasound

Oncology, 1993
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.

Microbubbles assist goat liver ablation by high intensity focused ultrasound

European Radiology, 2006
High intensity focused ultrasound (HIFU) has been introduced to treat cancers. However, this therapy is a time-consuming procedure; destructing a deeper volume is also difficult as ultrasonic energy attenuates exponentially with increasing depth in tissues. The aim of the present study was to investigate the effects of introducing microbubbles on liver

Laparoscopic partial kidney ablation using high-intensity focused ultrasound

The Journal of the Acoustical Society of America, 2001
A laparoscopic ultrasound probe was developed for image-guided high-intensity focused ultrasound (HIFU) ablation of renal tissue. The probe expands the application of a commercially available HIFU system (SonablateTM) to laparascopic operations. It consists of a 4-MHz focused rectangular HIFU piezoceramic transducer (30×10 mm, FL=30 mm) confocally ...

High Intensity Focused Ultrasound Renal Tissue Ablation: A Laparoscopic Porcine Model

Journal of Urology, 2009
High intensity focused ultrasound for renal lesions is still experimental. In a porcine model we evaluated the safety and efficacy of a newly designed laparoscopic high intensity focused ultrasound probe and software that allows real-time ultrasound guidance during renal tissue ablation.A Sonatherm 600 high intensity focused ultrasound system with a ...
