Submitted : Spring 2014 Fourier Transform is used in Magnetic Resonance Imaging (MRI) scans to simplify complex waves by rewriting the complex wave as a series of simple waves, such as sine or cosine waves. In order to accurately understand Fourier Transform, there must be a basic understanding of the magnetic properties of the Magnetic Resonance magnet and Kspace. Data points are stored in Kspace and the number of data points on each filled line in Kspace creates a MRI scan of pixels. Using Fourier Transform, these pixels are assigned a grayscale color according to frequency amplitudes at specific spatial locations.
