Non-Cartesian reconstructions typically perform a convolution to interpolate irregularly spaced samples onto a regular grid. The number of coefficients in the convolution trades-off accuracy with speed. A radially symmetric convolution kernel provides a favorable trade-off as compared to a separable kernel with the same number of coefficients.
