Abstract
Proton beams can deliver a highly targeted radiation dose to a narrow volume defined by their Bragg peaks. However, Bragg peak range uncertainties persist during dose delivery. Fortunately, pulsed proton beams generate protoacoustic emissions proportional to absorbed proton energy, thereby encoding dosimetry information in a detectable acoustic wave. The present embodiments provide methods and apparatuses to derive and model protoacoustic imaging with an ultrasound transducer, and examine the frequency characteristics of protoacoustic emissions, which are crucial parameters in imaging resolution.
