High-Intensity Focused Ultrasound Ablation of Pancreatic Cancer
Digestive Disease Interventions, 2019AbstractPancreatic cancer is one of the leading causes of cancer deaths, and many patients, with advanced disease, suffer from severe pain that can heavily affect their quality of life. In patients with advanced disease, an eminent role is played by percutaneous techniques, which cause tumor necrosis with a minimally invasive approach.

Generation of uniform lesions in high intensity focused ultrasound ablation
Ultrasonics, 2013High intensity focused ultrasound (HIFU) is emerging as an effective oncology treatment modality according to the clinical experience in the last decade. The temperature at the focus can reach over 65°C within seconds, denaturing cellular proteins and resulting in coagulative necrosis.

Generating Uniform Lesions in High Intensity Focused Ultrasound Ablation
Proceedings of Meetings on Acoustics, 2012High intensity focused ultrasound (HIFU) is emerging as an effective oncology treatment modality. Because of thermal diffusion from nearby spots, the lesion size will gradually become larger as HIFU progresses. However, uniform lesions with the least energy exposure are preferred by the physician in tumor ablation.

Tissue Ablation in Benign Prostatic Hyperplasia with High Intensity Focused Ultrasound
Journal of Urology, 1994In a phase I clinical trial the morphological impact and safety of high intensity focused ultrasound administered transrectally for tissue ablation in prostates from 22 patients undergoing subsequent prostatectomy were evaluated. Location and size of the tissue lesions correlated well with the predefined target area and revealed sharply delineated ...

High Intensity Focused Ultrasound (HIFU) Ablation
2012The 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 and antitumor immune response
The Journal of the Acoustical Society of America, 2013The 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 ...

Safety and Efficacy of High Intensity Focused Ultrasound Ablation Therapy for Adenomyosis
Academic Radiology, 2009In patients with adenomyosis, the severity of symptoms correlates roughly with the extent of adenomyosis. Thus, it was hypothesized that the ablation of enough volume of adenomyosis might alleviate symptoms. The aim of this study was to investigate the safety and efficacy of high-intensity focused ultrasound (HIFU) ablation for the treatment of ...

In vitro ablation of cardiac valves using high-intensity focused ultrasound
Ultrasound in Medicine & Biology, 2005The purpose of this study was to evaluate the possibility of using high-intensity focused ultrasound (US), or HIFU, to create lesions in cardiac valves in vitro. Calf mitral valves and aortic valves were examined. Focused US energy was applied with an operating frequency of 4.67 MHz at a nominal acoustic power of 58 W for 0.2, 0.3 and 0.4 s at 4-s ...

In Vitro Atrial Septal Ablation Using High-Intensity Focused Ultrasound
Journal of the American Society of Echocardiography, 2012High-intensity focused ultrasound (HIFU) has been applied clinically as a noninvasive therapeutic tool. Atrial septostomy is a palliative treatment for pulmonary artery hypertension. The purpose of this study was to assess the feasibility of atrial septal ablation in vitro using HIFU.Fourteen sections of atrial septum from pig hearts were treated ...
