1. A method of generating an apodization parameter for adjusting data received from a given transducer element as part of a beam-forming function in a medical diagnostic ultrasound apparatus, comprising the steps of:

  • defining a look-up table comprising K number of apodization parameter entries;

    identifying a length of an aperture in a direction of interest in transducer element units;

    identifying unit position of the given transducer element within the aperture;

    deriving a pointer into the look-up table as a function of at least said length, said unit position and the number K;

    selecting an apodization parameter from the look-up table based upon said pointer, wherein the selected apodization parameter is for adjusting data received from the given transducer element as part of a beam-forming function.
