Research output: Contribution to journalConference article


Using an exact theory of Beissner an experimental methodology is developed to accurately measure the effective radii of unfocussed, 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.
