Analysis of Fourier volume rendering

The Fourier volume rendering technique, operating in the frequency domain, has a significant computational efficiency advantage over spatial domain rendering, especially for data acquired in MR Imaging. The key operation in this rendering procedure involves a frequency domain resampling and filtering scheme for extracting a 2D plane from the 3D spectrum. With the appropriate selection and design of these interpolation filters, the dominant artifacts, ghost replicas, are reduced to a minimum without any increase in computational cost. The rendering results from using an optimal interpolation filter are compared with those from using other interpolation techniques such as linear and high resolution cubic splines
