When the treatment volume conforms to the shape of the tumor, the relative toxicity of radiation to the surrounding normal tissues is reduced, allowing a higher dose of radiation to be delivered to the tumor than conventional techniques would allow.
Cando o volume do tratamento é concordante coa forma do tumor, a toxicidade relativa da radiación para os tecidos circundantes normais é reducida, o que permite administrar unha dose máis alta de radiación ao tumor do que permiten as técnicas convencionais.
