Proposal and Analysis of "Ternary" Model of Sensitization for Proton Therapy

Zhongguo yiliao qixie zazhi
In order to improve the biological effect of proton therapy, the authors first propose a new method of boron-based proton-enhanced radiotherapy in a " ternary " radiotherapy mode, based on the existing sensitizing effect of proton radiotherapy: i.e ...
