Estimation of the radiation dose delivered to any point outside the target volume per patient treated with external beam radiotherapy.

摘要: The methodology we have developed to study dose distribution outside the target volume during external beam radiotherapy allows us determine received by patient arising from leakage radiation and scattered both head of treatment machine room. It also evaluate due photon scattering in means a dedicated 3-D algorithm permitting computations for whole body taking into account height, sex anatomical data at time treatment, dosimetric lung heterogeneity parameters. This offers solid criteria recommendations concerning protection.
