Manufacturing of 3D Printed Boluses for Use In Electron Radiation Therapy

This research demonstrates that a 3D printed bolus can be customized for electron
radiation therapy. Both extruder and powder based printers were used, along with, paraffin
wax, super stuff, and H20. The plan dose coverage and conformity for the planning target
volume (PTV), was such that the distal side of the PTV was covered by the 90% isodose
line. The structure is read, and converted into an STL file. The file is sent to a slicer to
print. The object was filled with parafin wax, superstuff or water and sealed. Materials
Hounsfield units were analyzed, along with the structure stability. This method is evaluated
by scanning the 3D printed bolus. The dose conformity is improved compared to that with
no bolus. By generating a patient specific 3D printed bolus there is an in improvement in
conformity of the prescription isodose surface while sparing immediately adjacent normal
tissues. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2017. / FAU Electronic Theses and Dissertations Collection
