Webphantom has negligible uncertainty compared to liquid water, and also helps to reduce the uncertainties in depths that are positioned at the near surface [11]. The physical density of RW3 water-equivalent phantom is 1.045 g cm-3 and the phantoms consist of 40 x 40 cm2 slabs of various thicknesses ranging from 1–10 mm. WebA homogeneous RW3 phantom and the thin RW3 slab placed at a clinical distance away from the phantom were scanned using a CT simulator. The resulting CT images were transferred via DICOM to the TPS and the density of the CT data corresponding to the thin RW3 slab was changed to 1 g/cm3.
