An ultrasound acoustic scan conversion device includes an accumulator, an error correction logic unit, and a walk controller. The error correction logic unit is responsive to the accumulator and contains an error correction circuit. The walk controller is responsive to the accumulator and generates a display memory address and selects increment values for the accumulator. A method of performing scan conversion in an ultrasound system is also provided. The method includes the steps of loading at least one register within an accumulator, producing an acoustic coordinate responsive to the accumulator, producing a natural grid acoustic range value, offsetting the acoustic coordinate to produce a natural grid acoustic range value, addressing the acoustic data memory with an acoustic data memory address responsive to the natural grid range value, generating a display memory address corresponding to the acoustic data memory address, and addressing the display memory with the generated display memory address.
