Witryna20 lip 2024 · This study evaluated the feasibility of utilizing a 3D-printed anthropomorphic patient-specific head phantom for patient-specific quality assurance (QA) in intensity-modulated radiotherapy (IMRT). Contoured left and right head phantoms were converted from DICOM to STL format. Fused deposition modeling (FDM) was used to construct … WitrynaThe CIRS Model 002PRA IMRT Pelvic 3D Phantom for film and ion chamber dosimetry is designed to address the complex issues surrounding commissioning and …
Witryna9 lip 2009 · A polyethylene slab phantom (25×25×15 cm 3) was used for measurements with SSD = 93.7 cm and film insert depth of 5.30 cm. Comparison using profiles, isodoses as well as the gamma evaluation (criteria: 3%/3 mm) was presented. Results Our results indicate that the isodose curves of reconstructed dose overlap well with …
