Resumen:
Before bone marrow transplantation, it is necessary to deliver
chemotherapy, radiotherapy or both in order to prepare the organism to
receive healthy bone marrow from a donor without rejection. One of the
methods used in radiotherapy is the volumetric arc therapy technique
(VMAT). This modern technique was used to perform a total marrow
irradiation (TMI) in a humanoid phantom with skeleton and other
tissue-equivalent organs. The absorbed dose in target volume (bone
marrow) and different organs in the anthropomorphic phantom was
determined for TMI with the VMAT technique delivered with 6 MV photon
beam energy from a TrueBeam linear accelerator in the radiation therapy
service at Instituto Nacional de Ciencias Medicas y Nutricion Salvador
Zubiran. The results show a homogeneous and acceptable coverage of the
target tissue (bones) sparing at the same time the organs at risk.
