Abstract
In a conventional ultrasound digital sector scanner, the sampling space is in the polar coordinates while the display space is in the Cartesian coordinates, which necessitates a coordinate transformation process. As a result a number of artifacts appear in displayed image. Recently, a new data space, to be called the uniform-ladder space (ULS), in which the sampling space is the same as the display space, has been introduced. In this approach, sampled points are uniformly distributed in each horizontal line as well as in each radial ray so that the data are displayed as they are acquired without any interpolation process required. In this paper mathematical models of various interpolation schems are devised to compare their performance.
