Abstract

This study compares the TE and UTE is to evaluate. We was programming by DWT of Matlab Tool-box for evaluation. M-program used feature value extract between TE Images and UTE Images. Two images using the extracted feature values were compared. Comparison of similar features two images phase was found to have value.

본 연구에서는 MR영상의 신호획득 기법 중 TE(Time of Echo)신호와 움직임에 의한 인공물을 줄이기 위하여 신호수신 시간을 짧게 하는 UTE(Ultra Time of Echo)기법으로 신호를 획득하여 TE신호와 UTE신호의 차이를 공학적 도구인 MatLab의 DWT(Discrete Wavelet Transform) ToolBox를 이용하여 프로그램밍을 하여 특징을 추출한 후 UTE 기법의 유용성을 평가하고자 하였다. 추출된 특징값을 이용하여 TE신호(T2) 특징값과 UTE신호 특징값을 비교한 결과 거의 일치함을 알 수 있었다.
