“Thermoacoustic range verification during conventional dose rate delivery by a synchrocyclotron” shows that the thermoAcoustic Range Verifier (tARV) can be setup in 10 minutes and provide millimeter range accuracy in an ultrasound quality assurance phantom.
A Mevion Hyperscan delivered up to 8 pC/pulse to a 3x3x3 lattice of spots. For each spot, 16 thermoacoustic pulses were averaged. Delivered dose was recomputed and imported into Raystation for comparison to planned dose.
DISCLAIMER: The tARV is a research tool and is not yet authorized for patient care.
