Claim 1:
2. The method of claim 1, further comprising the steps of:
defining an error value for the created constant beam width transducer shading function;
calculating an error between the created constant beam width transducer shading function and the user specified shading function parameters;
determining if the calculated error exceeds the defined error value;
increasing the number of Legendre polynomial orders if the calculated error exceeds the defined error value; and
repeating the steps of calculating coefficients, and creating a constant beam width transducer shading function with the increased number of Legendre polynomial orders if the calculated error exceeds the defined error value.
