[MRI] (영/한) Cross talk and Cross excitation artifact / 크로스토크, 크로스여기 인공물
(English) Cross Talk Artifact? It means that proton lose energy and it affects the adjacent slices. The adjacent proton also loses energy by T1 relaxation (spin-lattice relaxation) of proton in the selected slice and it is different from the cross excitation artifact. Cross Excitation Artifact? As explained in the last section, the shape of the RF is not square. Therefore, if the image is obtain..
[MRI] (영/한) Image parameter(4) - Slice thickness , Slice gap / 영상변수(4) - 절편두께, 절편간격
(영어/영문/English) 7. Slice thickness Width of the slice to be scaned Adjusting the width of the slice by passing a positive current to one side of the slice selection gradient coil and a negative current to the other side. (If a high current is passed, the thickness of the slice becomes thin, and when a low current is passed, the thickness of the slice becomes thick.) As the thickness of the slice..
