Let Us Introduce You to the tARV

The thermoAcoustic Range Verifier (tARV) system is a research tool that provides a non-invasive, non-ionizing means of acquiring signals that can be analyzed for accurate and precise localization of the Bragg peak relative to anatomical structures. This wireless device may have the potential to assist in adaptive planning decisions and be integrated with clinical workflow.

2023 : 6-channel wireless DAQ and AML enables easy lateral positioning. (tARV circled in red) 

2024: tARV provides 2 mm range accuracy on ultrasound QA phantom. (tARV circled in red)
