本研究是要探討並評估將超音波應用在傳統中醫”針”與”灸”療效的可行性。具體的作法是用不同頻率、功率、脈衝重複頻率的超音波，傳入於不同穴位上，然後再用傳統的針灸方法作對照，以尋找出最好的超音波療效方式。其間也想同時用傳統與超音波的刺激法，探討超音波的輔助療效。若得到非常正面的結果與最佳的超音波作用方式，此研究將會進一步發展成現代化的儀器，以用來作為傳統針灸的另一種替代方式或是輔助治療方法。

所設計的超音波針灸儀系統，主要是由自己設計並委託製造的聚焦式換能器、脈衝訊號產生器（pulse function generator）和一部功率放大器（power amplifier）所組成。不同中心頻率（1-5MHz）的超音波換能器的聚焦點，會被設計在二到三公分間，以配合一般穴位的深度。實驗前，每一個換能器在不同的頻率的聲場，都會預先被掃瞄界定出來。超音波的溫度場，超音波力推動艾膏滲透入假體與動物皮膚的效能，都將被仔細量化出來。

在可行性完成後，將於下一年度根據所得到的溫度場、聲場、及艾膏滲透情形等資料，設計出整個超音波針灸儀系統模組，再於臨床上進行療效評估。

This research is to explore and evaluate the feasibility of applying ultrasound to the traditional Chinese medicine in the treatment of acupuncture. The ultrasound of different frequencies, power, and pulse repetition frequency will be transmitted into different positions of the body according to the meridian theory. To obtain the optimal treatment from ultrasonic acupuncture, results will be verified with those treatments by the traditional acupuncture. A further ultrasonic acupuncture system will be developed according to those parameters acquired from the feasibility results. The developing acupuncture system is hopeful to be another alternative for the assistance of treatment using the traditional acupuncture. 

The ultrasonic acupuncture system mainly includes focused transducers, a pulse function generator, and a power amplifier. The focal points of different ultrasonic transducers of central frequencies, between 1 to 5 MHz, will be designed to located at 2 to 3 cm of the tis
