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. Although this is not strictly correct, this usage is applied in this report (see also ‘Spread-out Bragg peak’). | The Bragg peak is a pronounced peak on the Bragg curve that plots the energy loss of ion beams during their passage through matter.

Maximum der Bragg-Kurve. Die Bragg-Kurve beschreibt den Energieverlust pro Weglängeneinheit beim Durchgang von Ionen durch Materie. Bei Protonen verläuft die Bragg-Kurve erst langsam ansteigend, bevor sie sehr schnell ansteigt und dann abrupt abfällt.
