Ultrasonics. Field characterization. Specification and measurement of field parameters for high intensity therapeutic ultrasound (HITU) transducers and systems Ingestion-build-81500 whereas a pH of greater1 Scope This technical specification is applicable to high intensity therapeutic ultrasound (HITU) devices, specifying: relevant parameters for quantifying the field; measurement methods at relatively low output levels and methodology for extrapolating these to higher therapeutic level fields; consideration of sidelobes and pre focal maxima; parameters relevant to HITU transducers of different construction and geometry, including non focusing,
