A technology for the calculation and manufacture of devices for shaping a proton beam in radiotherapy

A therapeutic proton beam for an actual irradiation procedure is shaped using customized collimator leaves made out of Cerrobend, while to make the proton-beam depth-dose distribution conformal to the target volume, so-called boluses (compensators) with sophisticated shapes are calculated and then f...

Description
Summary:A therapeutic proton beam for an actual irradiation procedure is shaped using customized collimator leaves made out of Cerrobend, while to make the proton-beam depth-dose distribution conformal to the target volume, so-called boluses (compensators) with sophisticated shapes are calculated and then fabricated to compensate for the heterogeneities of a patient’s tissues and organs in the beam path. This article describes the main stages of testing a technology for manufacturing bolus from industrial wax which was developed at the Medico-Technical Complex (MTC) at the Dzelepov Laboratory of Nuclear Problems, Joint Institute for Nuclear Research (DLNP JINR), by comparing the spatial dose distributions obtained under a computer simulation of proton irradiation and the actually measured ones under the experiment.
