Abstract

The treatment of obesity have been developed various devices for the treatment of obesity, the ultrasound is to be made after the state changes to become easy fat decomposition by heat and vibrations to facilitate the flow of blood and lymph fatty acid released into the blood. There is such ultrasonic transducer array is used in obesity therapy focusing angle of the transducer array and the frequency may have a significant impact on the degradation of fat. In this paper, we set the frequency that reaches the shortest time to a set temperature 27kHz, 1MHz, by applying a transducer with a diameter of 5mm, 10mm, 16mm for the frequency of 3MHz, obtain the wavelength and near the stomach in order to set the frequency of the transducer array, which was set to the focusing angle of the transducer with three contact surfaces. As a result, the time to reach the set temperature was short days when 3MHz frequency, the focusing angle is titrated is $40^{\circ}$.

비만을 치료하기 위해 다양한 비만 치료기가 개발되어 왔으며, 초음파는 온열 및 진동작용으로 지방이 분해가 되기 쉬운 상태로 변하게 만든 후 혈액 및 림프액의 흐름을 촉진시켜 혈액으로 지방산 배출이 될 수 있도록 한다. 이러한 초음파 비만 치료기에 트랜스듀서 어레이가 사용되는데 트랜스듀서 어레이의 집속각도와 주파수는 지방을 분해하는데 중요한 영향을 미칠 수 있다. 본 논문에서는 트랜스듀서 어레이의 주파수를 설정하기 위해 27kHz, 1MHz, 3MHz의 주파수에 직경 5mm, 10mm, 16mm의 트랜스 듀서를 적용하여 파장과 근위장을 구하여 설정온도에 가장 짧은 시간에 도달하는 주파수를 설정하고, 3개 면이 닿는 트랜스듀서의 집속 각도를 설정하였다. 결과적으로 3MHz 주파수 일 때 설정온도에 도달하는 시간이 짧았으며, 집속각도는 $40^{\circ}$가 적정하였다.
