The Bragg peak is a pronounced peak on the Bragg curve that plots the energy loss of ion beams during their passage through matter. For protons and other ions the peak occurs near the end of their range. In radiation therapy with ions the term ‘Bragg peak’ is used for the peak in the curve of absorbed dose against depth in the irradiated phantom or patient. (see also ‘[[Spread-out Bragg peak]]’).
