INRiM Ultrasound Laboratory (LabUS) carries out research, development and service activities in the field of ultrasound metrology, with particular reference to the realization, maintenance and dissemination of the national ultrasonic power standard. The laboratory operates as a metrological reference for the characterization of ultrasound probes and devices, ensuring the traceability of measurements to international standards.

Its activities include the measurement and evaluation of the main ultrasonic beam parameters, such as acoustic pressure, power and intensity, in support of biomedical applications. Probe characterization is performed using an automated scanning system that can employ a wide set of hydrophones, enabling spatial reconstruction of the ultrasonic field and the assessment of device performance under controlled conditions. The laboratory is also engaged in the design, development and characterization of dedicated insonation systems, operating over a broad frequency range (1–10 MHz), for biomedical research applications.

These systems are used for controlled ultrasound exposure studies and for the validation of new therapeutic methodologies, with particular attention to measurement safety and quality. The activities are carried out in collaboration with national and European partners and support technical standardization through participation in international committees and working groups.
