| Summary: | The use of Inverse Discrete Fourier Transform (IDFT)
implemented in the form of Inverse Fourier Transform (IFFT) is
one of the standard method of reconstructing Magnetic Resonance
Imaging (MRI) from uniformly sampled K-space data. In this tutorial,
three of the major problems associated with the use of IFFT in
MRI reconstruction are highlighted. The tutorial also gives brief
introduction to MRI physics; MRI system from instrumentation point
of view; K-space signal and the process of IDFT and IFFT for One
and two dimensional (1D and 2D) data. |
