functional imaging methods
Description: This comprehensive text delves into the workings of MRI scanners, elucidating the principles behind neuroimaging techniques such as the application of strong magnetic fields, radiofrequency pulses, and gradient coils. It discusses the behavior of protons under magnetic fields and the role of RF pulses in disrupting their alignment, leading to the generation of MRI signals. The text further explores the intricate processes of spatial encoding using gradient coils and Fourier transfor...
