High-Intensity Focused Ultrasound Ablation by the Dual-Frequency Excitation

IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2019
High-intensity focused ultrasound (HIFU) has emerged as an effective and noninvasive therapeutic modality for cancer and solid tumor. Despite its promising clinical outcomes and the approval of the Food and Drug Administration of many countries, the ablation time of a large target is long, so enhancement of the lesion production is highly desired.

Enhancement of ultrasound contrast agent in High-Intensity focused ultrasound ablation

Advances in Therapy, 2006
High-intensity focused ultrasound (HIFU) is becoming an increasingly attractive modality for ablation. Enhancement of HIFU is an important issue that has been discussed and investigated worldwide. Ultrasound contrast agents are considered to constitute an efficient medium for changing acoustic characteristics and improving energy deposition in the ...

Ablation of tissue volumes using high intensity focused ultrasound

Ultrasound in Medicine & Biology, 1996
Successful application of high intensity focused ultrasound to cancer treatment requires complete ablation of tissue volumes. In order to destroy an entire tumour it is necessary to place a contiguous array of touching lesions throughout it. In a study of how best to achieve this, exposures were selected to give single lesions that were thermal in ...

High-Intensity Focused Ultrasound Ablation Therapy of Gliomas

2018
Ultrasound in clinical medicine is most commonly associated with imaging, but can be harnessed to yield an array of biological effects, including thermal ablation of brain tumors. Therapeutic ultrasound has been studied for many years, but only within the last decade has the technology reached a point where it is safe and practical for clinical ...

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 ...

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 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.

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 ...
