The application of ultrasound energy at much lower levels than is the current clinical norm is starting to gain ground as a therapeutic possibility. Clearly the applied energy is the same, it is the ‘dose’ which is different – most importantly, the intensity (W/cm) – which is MUCH lower – typically 2 or 3 times lower than the lowest setting on most regular clinical machines, with the most commo...

brain stimulation techniques are important in both basic and clinical studies. majority of well-known brain stimulating techniques have low spatial resolution or entail invasive processes. low intensity focused ultrasound (lifu) seems to be a proper candidate for dealing with such deficiencies. this review recapitulates studies which explored the effects of lifu on brain structures and its func...

abstractbackground : in order to quantify effects of ultrasound irradiation parameters under therapeutic condition, especially sonodynamic therapy, it is initially necessary to evaluate inertial cavitation activity in vitro conditions therefore, in this study, the effect of 1 mhz low level ultrasound based on °oh radicals generated by acoustic inertial cavitation in aqueous solution was monitor...

In order to study the effect of ultrasound (US) on bone healing, a complete transverse fracture was made in the right radius of adult male rabbits by a cutter. 52 rabbits were used: group I. control (n= 17): group 2. test (n:=: 15): group 3, intact (n= I) and group 4 (n= 12) who were examined only for evaluation of the cutter effects in detail. 7 animals were operated with a Gigli saw. The ...

The ability to sense and respond to physical stimuli is an important key of the life. It was recognized that ultrasound as a physical stimulus could produce drastic changes in biological systems. High-intensity ultrasound is well known to be destructive to biological materials, but low-intensity ultrasound, on the other hand, has shown a range of biological effects with potential significance i...
