The Biophotonics Group maintains a dedicated space for the development and precision characterization of ultrasound therapeutic probes, supporting translational research in acoustic-based therapies. Using the AIMS III Hydrophone Scanning System, in combination with the AQUAS-10 Water Conditioner and HNR-series Needle Hydrophone, we perform 5D acoustic field mapping in both near- and far-field regions. This includes detailed analysis of parameters such as attenuation, beam profile, and pressure distribution, with a spatial resolution of approximately 5 µm.
The system features a high-resolution, point-based needle hydrophone that avoids signal integration, allowing for accurate and localized measurements. Temperature sensing is used to precisely determine the distance between the probe and the target object, enhancing spatial accuracy. The setup also includes angular control for probe orientation, enabling comprehensive probe characterization workflows.
Over 100 acoustic parameters are calculated during each scan, including key metrics such as Prms (root mean square pressure), Pii (peak intensity integral), Ispta (spatial peak temporal average intensity), TI (thermal index), and MI (mechanical index). These measurements provide a robust foundation for evaluating probe performance and safety in therapeutic applications.
