Magnetic resonance imaging is a widely used noninvasive medical imaging technique to visualize the inner part of human body. It applied the basic principles of nuclear magnetic resonance (NMR) spectroscopy, which provides both chemical and physical information of molecules. WebSiemens Medical Solutions USA. In a number of medical imaging modalities, the Fast Fourier Transform (FFT) is being used for the reconstruction of images from acquired raw data. In this chapter, we present an implementation of the FFT in a GPU performing image reconstruction in magnetic resonance imaging (MRI) and ultrasonic imaging.
