Abstract
To assess the ability of an extravasation detection accessory (EDA) system to detect clinically important extravascular injection of iodinated contrast material delivered with an automated power injector. Fifty patients referred for contrast material enhanced body computed tomography studied in a prospective, observation study in which the EDA system was used to identify and interrupt any injection associated with clinically Important extravasation. The presence or absence of extravasation was definitively established with multi-detector CT at the injection site (injection rate,
CT 검사에서 조영제의 혈관외유출을 예방하기 위해 EDA시스템을 증폭기, ADC, 스트레인 게이지로 구성하여 개발하였고, 스트레인 게이지의 신호의 수치를 나타내도록 프로그램을 설계하였다. 신호비율은 500/1000 sec, 분해능 값은 0에서 4,096범위로 표시하고, 입력범위
