Increasing importance of proton therapy

Waldemar Ulmer


During the past decade, many proton therapy facilities have been established or are planned to become available very soon. Thus it is amusing that in the meantime much more vendors of proton treatment machines offer these facilities than corresponding machines working either with bremsstrahlung or fast electrons. Many researchers in the field of radiotherapy have expressed the opinion that about 20 % of malign tumors can be better treated with protons due to the rapid fall-off behind the Bragg peak than with the conventional radiotherapy with ultra-hard photons or electrons. Thus the normal tissue can be better protected by this behavior, whereas photons may travel long distances behind the target.
