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. Our implementation automatically balances the load between the vertex processor, the rasterizer, and the fragment processor; it also uses several other novel techniques to obtain high performance on the NVIDIA Quadro NV4x family of GPUs.

Background

The FFT has been implemented in GPUs before (Ansari 2003,
