  Development and Radiological Validation of Heterogeneous Pelvic Phantoms Against a Patient-Derived Distribution: A CT-Based Benchmarking Study of Rectal and Bladder Surrogates
  Author(s): Wiam EL ATIFI*, Abdelali SLIMANI and Omar EL RHAZOUANI
  
  Background: Heterogeneous physical phantoms reproduce pelvic organ anatomy, yet their radiological representativeness at both whole-organ and wall-contour levels has not been evaluated against clinical CT data. This study benchmarks two heterogeneous phantoms — a polyurethane foam-walled rectal phantom and an epoxy-walled, water-filled bladder phantom — against 50 cervical cancer patients. Materials and Methods: CT-derived mean Hounsfield unit (HU), electron density (ED), and volume were extracted from whole-rectum, rectal-wall, whole-bladder, and bladder-wall contours in 50 female patients (120 kVp, 400 mAs, 0.25 cm slice thickness) using the Elekta Monaco treatment planning system. Both phantoms were geometrically derived from an independent 200-patient average model and scanned under identical CT conditions. A three-tier percentile scoring framework (P25–P75: 2 po..
