SummaryThe CTDI Head and Body Phantom in PMMA is a cylindrical set designed for measuring the computed tomography dose index (CTDI) and dose-length product (DLP) on CT systems. Compliant with IEC 61223-3-5 and IEC 61223-2-6, it enables dosimetric performance assessment and constancy checks of clinical CT protocols.
Composition and modules- Two cylindrical modules: head and body.
- Head module: external diameter 160 mm (16 cm), thickness 150 mm.
- Body module: external diameter 320 mm (32 cm), thickness 150 mm.
Holes and accessoriesEach module includes apertures for CTDI-100 ionization chambers: one central hole and four peripheral holes arranged at 90°, located 10 mm from the outer edge. Acrylic plugs are supplied to close unused cavities. Engraved alignment axes facilitate centering on the CT table.
ApplicationsThis phantom is used for CT dose measurements (CTDI and DLP), protocol validation, constancy checks of equipment and reproducibility studies of patient doses.
