Abstract :
Using an exact theory of Beissner an experimental methodology is developed to accurately measure the effective radii of unfocused, circular plane piston transducers. The transient and steady-state diffraction concepts described by Lord are also used to propose an extension of the definition of the AIUM/NEMA pulse intensity integral to properly analyze cw and tone burst data
