WebMay 24, 2024 · This causes the radiation dose to increase dramatically. This large dose spike at the end of the protons path is known as the Bragg peak. By changing the proton beam energy, we can move the Bragg peak to different depths within the patient. We now have a dose maximum at the position of the tumor. WebMay 18, 2024 · This pronounced dose peak is called the Bragg peak. Notice that the depth of the Bragg peak is determined by the initial proton energy and the width of the Bragg peak is the result of a small variation of the energy loss of protons, because each proton has a unique interaction history. Also, observe that beyond the Bragg peak there is no dose.
