A specific increase in temperature is necessary to achieve a temperature-mediated therapeutic impact by ultrasound in rehabilitation. In order to obtain a physical basis for a definite temperature rise at a certain depths in the human body a human cadaver study in situ was conducted. A set of 16 experiments was carried out with an ultrasound frequency of 1 and 3 MHz. For each frequency the puls...

With the amazing successes that have been reported over the past 10 years, it is easy for researchers in therapeutic ultrasound to be seduced by the appeal of biological and clinical studies but understanding the biology alone is insufficient. All good science requires repeatability, and developing a successful therapy is no different. It is imperative from both a scientific and a commercial pe...

Ultrasonic nebulization therapy (U/air) resulted in a decline in Pa02 of -5 to -22 rnm H g in ten of 15 chronic obstructive lung disease (COLD) patients. A similar decline in Pa02 occurred in four of ten COLD patients when ultrasonic nebulization was given with intermittent positive pressure breathing (IPPB [IPPB/U/air]). Complaints of discomfat from treatment were elicited in ten of 15 COLD pa...

Time reversal is a very powerful method for focusing through complex and heterogeneous media and shows very promising results in biomedical applications. In this paper, we review some of the main applications investigated during the past decade. An iterative implementation of the time-reversal process allows tracking gallstones in real time during lithotripsy treatments. In this application dom...

Aim: To compare the clinical benefit of full-mouth ultrasonic debridement against partial-mouth ultrasonic debridement in patients with chronic periodontitis up to 3 months after therapy. Materials & Methods: Sixty patients with probing pocket depth ≥ 5 mm were randomly assigned to evaluate the clinical efficacy of full-mouth ultrasonic debridement against partial-mouth ultrasonic debridement i...

BACKGROUND Advances in nebulizer design have produced both ultrasonic nebulizers and devices based on a vibrating mesh (vibrating mesh nebulizers), which are expected to enhance the efficiency of aerosol drug therapy. The aim of this study was to compare 4 different nebulizers, of 3 different types, in an in vitro model using albuterol delivery and physical characteristics as benchmarks. METH...

Minimally invasive treatment options are an important part of the uterine fibroid-treatment arsenal, especially among younger patients and in those who plan future pregnancies. This article provides an overview of the currently available minimally invasive therapy options, with a special emphasis on a completely noninvasive option: magnetic resonance-guided focused ultrasound (MRgFUS). In this ...

With the popularity of ultrasound therapy in clinics, characterization of the acoustic field is important not only to the tolerability and efficiency of ablation, but also for treatment planning. A quantitative method was introduced to assess the intensity distribution of a focused ultrasound beam using a hydrophone and an infrared camera with no prior knowledge of the acoustic and thermal para...

The aim of the present study was to evaluate the efficiency of high intensity laser and ultrasound therapy in patients who were diagnosed with lumbar disc herniation and who were capable of performing physical exercises. 65 patients diagnosed with lumbar disc were included in the study. The patients were randomly divided into three groups: Group 1 received 10 sessions of high intensity laser to...
