A digital scan conversion algorithm using fourier transform

In clinical ultrasound scanners, the echo data from phased or convex arrays are acquired in the polar coordinates but need to be displayed in the Cartesian coordinates. This requires a coordinate conversion process. In this paper, we present a method of performing scan conversion in the frequency do...
