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...

| description | 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 domain using Fourier transform. Performance comparison of spatial and frequency domain scan conversion algorithms is carried out by computer simulation. We show that the frequency domain method produces B-scan images comparable to the bilinear interpolation method. |
