Validation of polylactic acid polymer as soft tissue substitutive in radiotherapy
DD Pereira, SC Cardoso, LAR da Rosa… - Radiation Physics and …, 2021 - Elsevier
We report the experimental study on the physical and radiation properties of polylactic acid
polymer (PLA-C 3 H 4 O 2) combined with Monte Carlo simulations for application in
radiotherapy. The suitability of PLA for phantoms construction as a substitute for soft human
tissue in MeV photon radiation dosimetry and therapy is discussed. The elemental
composition and radiation properties are described as recommended by ICRU 44. In
addition, Hounsfield unit (HU), mass attenuation coefficient, mass stopping power and tissue …
