In this study, temperature distribution inside a tissue - mimicking material induced by HIFU (High Intensity Focused Ultrasound) transducer was investigated with two different methods. first method T-type thermocouple (TC) sensors and in second method, infrared (IR) camera system used for determining the on tissue-mimicking (TMM). Temperature increase TMM have been characterized during ultrasonic power application. measurements were actualized which has characteristics very similar to human...
Realization of temperature characterization on focused ultrasound treatment devices by using tissue-mimicking phantom systems (Tissue-Mimicking Material, TMM) is indispensible in pre-clinical studies. In this survey, order to examine the viscous heating effect thermocouples, rise due excitation a HIFU transducer has been measured two different types T-type thermocouples embedded inside TMM. obtain values from more effectively, PC-based multi-channel data acquisition and monitoring interface...
Ultrasonic devices are today widely used in hospitals for diagnosis and treatment purposes. Quality controls of ultrasonic the field health must be performed on phantoms that simulate human tissue with similar acoustic properties to terms both safety proximity reality. The very important materials calibration ultrasound devices, performance tests, improvement signal noise ratios existing systems, practical application users before device use interpretation images taken during it is...
In recent years, High Intensity Focused Ultrasound (HIFU) has been actively used in clinical practice for the treatment of some types cancer. However, as other cancer methods, dosimetric studies have to be carried out order achieve effective treatment. For HIFU applications, are performed temperature characterizations on tissue mimicking materials (TMM) that simulate acoustic properties selected tissues. due acoustical each different, it is thought would give more accurate results by using...
In this study, the optical properties of Zerdine® phantom such as transmittance, absorbance, reflectance, refractive index, and attenuation coefficient have been determined by using two different methods. One method is based on power measurements made with without a 635 nm laser in homogeneous medium, while other determination basic single integrating sphere system. As result, it was that data obtained integrated system were closer to actual data. Furthermore, similar also calculated for Agar
In backing materials of ultrasonic transducers, filler powders such as tungsten, iron, magnesium and aluminum are generally used. commercial probes, there composite support consisting epoxy in which the tungsten particles joined. Therefore, first part study, 1 g, 2 5 g 10 powder mixture were added to 80-20, 85-15 87.5-12.5 ratio mixtures prepared by weight hardness values these at end waiting periods have been measured evaluated. second densities, sound velocities attenuation coefficients...
The heating effect produced by a focused ultrasound transducer has been investigated using visual techniques with positioning system. Ultrasound power, distance, frequency and harmonics of was investigated. Three experiments were performed on TMM (Tissue Mimicking Material), sheep liver lung. HIFU (High Intensity Focused Ultrasound) resonance 1.1 MHz 3.3 used as source. Effect in lung's pieces displayed dimension cauterization measured. Previous temperature measurement results for compared...

In present study, temperature rise in a tissue - mimicking material induced by HIFU (High Intensity Focused Ultrasound) transducer was examined with two different methods. order to determine the inside and distribution on surface of Tissue-Mimicking Material (TMM), T-type thermocouple (TC) sensors infrared (IR) camera system used first second method respectively. During ultrasonic power application, increase TMM have been represented. Temperature measurements were realized which has...
In our country, in many different brands and types of ultrasound devices are used very intensely the health sector. However, these do not pass a mandatory/legal or voluntarily technical measurements/controls. order to verify indicated performance safety ultrasonic probes that is most important part devices, measurements/controls required be done as per strong scientific parameters standards. For this reason, Portable Ultrasonic Wattmeter device has been designed, manufactured tested. The...
Hearing aids are auxiliary instruments that used to reduce or minimize the adverse effects of hearing loss. There many different brands and types products in aid market. The testing performance parameters which show can operate according defined standards is great importance both for manufacturers patients with problems. In this study, tests an as actively a person living loss were performed "IEC 60118 Electroacoustics - Aid" series standards. made explained on basis information literature.
Light therapy devices generally use laser light, light-emitting diodes (LEDs), and intense pulsed lights (IPLs) as a source of light energy. LED is treatment that allows the skin to self-heal with all other treatments. The most important feature application activate shorten renewal process. In this study, effects an device within tissue-mimicking material on its surface were investigated. Our aim here determine how many different (such red, yellow, green, blue, orange purple) present in...
In this article, correlation between of Phi6 bacteriophage virus (equivalent SARS-CoV2) spread and disinfection methods are pointed out. Most the existing including thermal (UV), physical chemical were applied new (infrared (IR) microwave (MW)) proposed, studied presented. The containing aerosols droplets was investigated by means Brownian motion simulations using COMSOL software visualized a powerful laser high speed camera. Comparative studies have been done for IR, MW, UV, chemicals...
It has been reported in the literature that low-level laser therapy is non-invasive, no obvious side effects, a very low cost, and an effective new treatment technique. published works at between 1 mW 500 power, 390 nm 1100 wavelengths without causing harmful heat to human body, this technique, high intensity, monochromatic, narrow-band light source applied locally. also stated technique instead of producing thermal effect, photochemical reactions cells are stimulated, allowing tissues heal...
A modified radiation force balance (RFB) system was established for physiotherapy and high intensity therapeutic ultrasound (HITU) power measurements in the Medical Metrology Laboratory at National Institute of Turkey (UME).
