- The study focuses on creating and testing 3D printed dosimetry phantoms for brain cancer radiation therapy at the Australian synchrotron, using various materials like Polylactic acid (PLA+) and tricalcium phosphate.
- Different phantoms, including slab, preclinical rat, and anthropomorphic head models, were evaluated for their accuracy and effectiveness in measuring radiation doses.
- Results showed that PLA+ phantoms closely match water and bone equivalents in terms of radiation attenuation, making them reliable tools for quality assurance in synchrotron dosimetry.
This study aims to characterize radiological properties of selected additive manufacturing (AM) materials utilizing both material extrusion and vat photopolymerization technologies. Monochromatic synchrotron x-ray images and synchrotron treatment beam dosimetry were acquired at the hutch 3B and 2B of the Australian Synchrotron-Imaging and Medical Beamline.Eight energies from 30 keV up to 65 keV were used to acquire the attenuation coefficients of the AM materials.
