방사선사나라 Radiographer Nara
[MRI] (영/한) Image parameter(5) - Bandwidth , Saturation Pulse / 영상변수(5) - 주파수폭, 포화펄스
(영어/영문/English) 9. Bandwidth It refers to the range of frequencies and uses Hertz units The receiver bandwidth is an important factor in determining the SNR of an image, and it means the range that receives the echo signal from the tissue receiving the RF pulse and is expressed as ± Hz based on the center frequency. SNR = √ (old bandwidth / new bandwidth) When the receiver bandwidth is wide, noi..
