The addition of contrast agent microbubbles during HIFU can increase the temperature dramatically compared to conventional HIFU. Higher microbubble concentrations enhance this phenomenon but they also cause acoustic shadowing along the path of the HIFU beam and thus local injections are preferred over systemic delivery.

2009 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2009
MR guidance of high intensity focused ultrasound is evolving with each new application. In this paper we describe ongoing research in the MR-guidance aspect of MR-guided focused ultrasound. The structure is divided into the pretreatment/setup phase of the procedure, MR thermometry for monitoring the actual treatment, and methods for assessment and ...

Characterization of HIFU fields inside of a tissue-mimicking HIFU phantom
The Journal of the Acoustical Society of America, 2019The use of a tissue-mimicking, scatterer-free polyacrylamide gel phantom for HIFU has been previously described [1]. This transparent material combines with a marker with an absorption of 0.6 dB/cm MHz which turns opaque when the temperature exceeds 65 °C.

Complications of HIFU Ablation
2021Any surgical procedure has potential complications. Abdominal and laparoscopic surgery may have heavy bleeding at operation, infection, poor wound healing, pelvic adhesion, ureter or bladder injury, bowel injury, and many others. HIFU ablation involves no wound, no bleeding, and is a type of noninvasive treatment.

Adenomyosis is due to the invasion or presence of endometrial glands in the uterine myometrium accompanied by hyperplasia and hypertrophy of the surrounding muscle cells, forming diffuse or focal lesions. Adenomyosis occurs most often in women between the ages of 30 and 50, but it can also be in younger women who have not had children. The incidence of

The field of high intensity focused ultrasound (HIFU) is developing rapidly. For basic research, quality control, and regulatory assessment a reusable phantom that has both thermal and acoustic properties close to that of soft tissue is critical. A hydrogel‐based tissue mimicking material (TMM) has been developed that shows promise for such a phantom ...
