(영/한) [MRI] What is the Net magnetization? - 순자화란?
(영문, 영어, English) The protons with magnetic dipoles are divided into protons of low energy level precessing in the same direction with respect to the magnetic field applied from the outside, and protons of high energy level precessing in the opposite direction. That is, there are spins in the two orientations, parallel (also known as spin up) and antiparallel (spin down). At this time, more will..
(영/한) How do we actually perform MR imaging? - MRI사진 얻는 법
(영어, 영문, English) Low-frequency radio waves penetrate the tissue and reflect back off magnetized spins within the object. In MRI, an RF wave, or an RF pulse, is transmitted into the patient, and a signal is received from magnetized spins (protons) in the body. 1. If spining and unpaired protons are placed in an external magnetic field, they will lined up with that magnatic field. (It's the time ..
