Acoustic Range Estimates: a prestigious publication for the thermoacoustic Range Verifier
Acoustic Range Estimates is delighted to announce that an upcoming publication will feature the tARV. The International journal of radiation oncology, biology, physics has accepted “Validation of a Cable-Free and User-Friendly thermoAcoustic Range Verifier for a 2 Gy Proton Field Delivered to the Liver of an Anthropomorphic Phantom” for publication.
The work, authored by S.K. Patch, V. Sarkar, A. Chiravuri, R. Vallejos and T. Lynch, aimed to detect and correct offline the proton range errors due to incorrect Hounsfield Unit-to-stopping power conversion with minimal (5-10 minute) extension of the patient-facing clinical workflow using the Acoustic Range Estimates’ cable-free thermoAcoustic Range Verifier (tARV). Measurements were carried out using two proton dual-field plans, delivered across seven energy layers to a hydrogel anthropomorphic phantom. The tARV was positioned along the beam path to capture thermoacoustic signals via sagittal ultrasound imaging. Thermoacoustic estimates of range errors for clinical and stoichiometric dose-maps were found to be and , respectively. DVHs of recomputed and stoichiometric MC dosemaps were indistinguishable from each other but were clearly distinguishable from the clinical MC DVH. The work demonstrated that the tARV is poised for efficient evidence development, such as noninterventional patient safety and offline adaptive studies.
