Abstract

The acoustic pressure field mapping system of Ultrasound Laboratory (Labus) of Institute of Metrology, Standardization, and Industrial Quality (Inmetro) is being implemented, based on Standard IEC-61102. This system will be capable to estimate ultrasound pressure field parameters from biomedical transducers, essential step to calibration and certification of ultrasound equipments. The data acquisition is carried out on a water bath, where a positioning system moves a hydrophe, which produces electrical signals in response to waterborne acoustic signals, over the transducer acoustic field. This work presents the implementation of acoustic pressure field mapping system, based on IEC-61102 that defines the necessary steps to acoustic beam assessment and calibration.
