Abstract—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. Keywords—Discrete Fourier Transform (DFT), K-space Data,
