Perfluorocarbon nanoemulsions (PFCNEs) have recently been undergoing rigorous study to investigate their ability to improve the therapeutic efficacy of tumor ablation by high intensity focused ultrasound (HIFU). For precise control of PFCNE delivery and thermal ablation, their accumulation and distribution in a tumor should be quantitatively analyzed. Here, we used fluorine-19 (19F) magnetic re...

Tissue destruction by thermal ablation occurs when the targeted delivery of heat or cold causes a rapid change in temperature (>55°C for heat or <−20–50°C for cold) in the local tissue environment. Imaging can be used to localize and target the thermal effects to the target/tumor for treatment, control the energy deposition, and assess treatment response. Therapeutic applications of ultrasound ...

Atomization and fountain formation is a well-known phenomenon that occurs when a focused ultrasound wave in liquid encounters an air interface. High intensity focused ultrasound (HIFU) has been shown to fractionate a tissue into submicron-sized fragments in a process termed boiling histotripsy, wherein the focused ultrasound wave superheats the tissue at the focus, producing a millimetre-sized ...

Attractivity of robotic high intensity focused ultrasound (HIFU) is based largely on the non-invasive, extremely precise nature of this high-tech robotic therapy as well as its clean, radiation free, surgical, but nevertheless, bloodless character. Today, in urological oncology, HIFU is used clinically as a therapeutic tool for the treatment of prostate cancer. Experimentally it is investigated...

aim and background: emotion focused couple therapy is one of the methods that has focused on the negative cycles of interaction caused from deep emotional vulnerability. the purpose of this study was to determine the effect of emotionally focused couple therapy on reducing the damage caused by marital infidelity. methods and materials: the statistical sample included 30 couples that were select...

High Intensity Focused Ultrasound (HIFU) is a definitive treatment for localized prostate cancer that is currently utilized most in Europe and Japan but it not yet approved by the FDA for this indication. Within the armamentarium of definitive prostate cancer therapies it is unique as it is truly non-invasive and does not involve incision or excision. The purpose of this paper is to review the ...

Ultrasound (US) thermotherapy is used to treat tumours, located deep in human tissue, by heat. It features by the application of high intensity focused ultrasound (HIFU), high local temperatures of about 90 degrees C and short treating time of a few seconds. Dosage of the therapy remains a problem. To get it under control, one has to know the heat source, i.e. the amount of absorbed US power, w...
