Localization of Bragg Peak based on waveform inversion and LTI algorithm
In order to make the localization of proton Bragg peak in media more accurate,so as to be used in clinical tumor localization and treatment,a three-dimensional Bragg peak localization algorithm is pro-posed.The algorithm is based on frequency domain full waveform inversion algorithm and LTI algorithm to locate Bragg peak.In this paper,five target Bragg peak locations are selected,and then 10 initial Bragg peak locations are randomly selected within 50mm from the center with these 5 coordinates as the center.The final location error converges to 0.2mm～1.7mm,which can well meet the positioning accuracy re-quirements of proton therapy.
