초록
본 연구에서는 자체 제작한 3종의 초음파 TM 팬텀의 음향학적 특성 및 온도 민감도를 측정하였으며, 초음파 영 상학적 특성을 관찰, 평가하였다. TM 팬텀은 폴리우레탄을 주재료로 국제전기표준회의(International Electronical Committee, IEC) 기준안에 따라 제작하였으며 외부 온도 변화 따른 초음파 영상학적 특성은 22℃ 이하에서 온도 감소에 따라 휘도 및 영상투과심도가 비례하여 감소하는 것이 확인되었다. 본 연구를 통하여 산란재 특성이 상이 한 TM 팬텀을 제작하는 기초자료를 제공하였으며, TM 팬텀의 사용 온도는 22℃ 이상에서 사용하는 것이 적합한 것으로 판단되었다
Abstract
The purpose of this study is that in measures the acoustic propagate characteristics and temperature sensitivity of ultrasound tissue mimicking phantom(TM phantom). TM phantom manufacture according to the International Electronical Committee(IEC) guidelines for acoustic propagate characteristics of soft tissue. TM phantom was observed to have the image brightness and the image depth penetration decreases changes convergence which was the subject of ultrasound image characteristics in accordance with an external temperature that the change is reduced in temperature below 22℃. This study provide a basis to create another TM Phantom and TM Phantom has been determined that it is appropriate for use in more than 22℃.
