[MRI] (영/한) Fractional NEX, Fractional echo / 부분 여기횟수, 부분 에코
(영어/영문/English) 1. Partial Fourier Phase Encoding (Fractional NEX) This refers to a method of filling only about half of the K-space (approximately 50 to 75%) with the actual scan data in the phase coding direction and filling the rest of the mirror data with symmetric data, and is called the Partial Fourier Phase Encoding or Fractional NEX. The scan time can be reduced to about half while the s..
[MRI] (영/한) Fast Gradient Echo / 고속 경사에코 기법
(영어/영문/English) Fast Gradient Echo pulse sequence? FSPGR, FGRASS and Turbo-FLASH are pulse sequences that can acquire a fast image using TR and TE which are shorter than the conventional gradient field echo. (Varies by equipment company) Methods used to reduce TR and TE 1. factional RF By applying a fractional RF pulse to the extent that the spins can be excited, the time of RF pulse applied to ..
