Background,Motivation and Objective Acoustic waves induced by megavoltage photon beam from a clinical linear accelerator(Linac) could provide location and dosimetric information of actual delivered radiation during the course of therapy.A different dynamic acoustic emission process induced by X-ray from Linac could represent a longitudinal and/or heterogeneous response to the treatment.However,to improve the signal to noise ratio(SNR) in X-ray acoustic signal detection,previous studies averaged the whole acoustic signals triggered by X-ray pulses,thus compromising diagnostic accuracy in personalized treatment efficacy.In this study,we investigated,for the first time,the technical feasibility of detecting the dynamic acoustic emission process induced by Linac with high SNR.
