초음파 조영제 주입 유무에 따른 음장 내 주파수 성분 특성 변화에 관한 연구

Ultrasound contrast agents(UCAs) was not only used to field of image ultrasound but also, field of therapeutic ultrasound studied that effectively treatment purpose. Especially, UCA frequently studied role of a heating catalyst. And It was studied to correlation analysis to change of frequency component by microbubble injection. In this study, perfom experiment to frequency component analysis in phantom with UCA injection. And it was obtained to impact of ultrasound input intensity and UCA injection to used frequency component analysis by phantom acquired signal.
