Fabrication Of Rhizophora Spp. Head Phantom For External Beam Radiotherapy Applications

The aim of this study was to fabricate a head phantom made from soy-lignin Rhizophora spp. for dosimetric applications in external beam radiotherapy (EBRT) of the brain. Three different particle sizes (0–103 μm, 104–210 μm, 211–500 μm) and different percentages of adhesives (0, 6 and 12%) were studi...
