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 ...

Tissue Ablation in Benign Prostatic Hyperplasia with High Intensity Focused Ultrasound

Journal of Urology, 1994
In 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 ...

In Vitro Atrial Septal Ablation Using High-Intensity Focused Ultrasound

Journal of the American Society of Echocardiography, 2012
High-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 ...

Extracorporeal application of high‐intensity focused ultrasound for prostatic tissue ablation

BJU International, 2005
Authors from Mannheim describe their experience with high‐intensity ultrasound for locally confined prostatic carcinoma. This was essentially an in vivo efficacy and safety study, as well as a clinical feasibility study. They found a positive answer to all questions asked.

Influence of ablated tissue on the formation of high-intensity focused ultrasound lesions

Ultrasound in Medicine & Biology, 1997
In order to ablate tumours using high-intensity focused ultrasound (HIFU) it is necessary to irradiate the tumour with a confluent array of single ultrasound exposures. We have identified a phenomenon that we term lesion-to-lesion interaction, which occurs when the spatial separation of individual exposures is such that an existing lesions appears to ...

Non-Invasive Transcranial Brain Ablation with High-Intensity Focused Ultrasound

2014
The idea to ablate brain tissue with high-intensity focused ultrasound (HIFU) in a highly precise and localized manner is relatively old. For HIFU tissue ablation, ultrasound (US) waves are concentrated to a focal point. Due to US absorption, the focal area will be heated and consequently thermally destroyed.
