ABSTRACT:
An apparatus and method for mapping data associated with spacial polar angles into a Cartesian coordinate system is disclosed. In the described application, ultrasound returns from a rotating transducer are mapped into a memory to permit presentation on a raster scanned display. A tangent function is used to compute X and Y locations in a digital differential analyzer. The selection of data for these locations is controlled with a secant function by a second digital differential analyzer to minimize quantizing errors.
