The Accu-Gold CT ionization chamber is designed for accurate measurement of Computed Tomography Dose Index (CTDI), Dose Length Product (DLP) and Dose Width Product (DWP) on modern CT scanners.
It provides a flat energy response across its entire active length, ensuring highly reproducible results both in-air and inside CT phantoms.
Two complementary models are available :
- 10X6-3CT : standard CTDI / DLP / DWP cylindrical chamber, 3 cm³ active volume, 100 mm active length, ideal for beam qualities from 100 to 150 kV.
- 10X6-0.6CT : small-volume (0.6 cm³) thimble chamber for narrow or high-dynamic multi-slice CT beams.
Each chamber is individually calibrated with traceable certification and fully compatible with Accu-Gold+, Accu-Dose+ and Accu-Gold Touch systems.
