Product catalog summary
Overview
The RTI CT Ion Chamber 30 cm is a robust, cylindrical, pencil-shaped vented ionization chamber designed specifically for CTDI (Computed Tomography Dose Index) measurements. It is used to measure and monitor the exposure output level of CT scanners, either within a phantom or free-in-air, in compliance with IEC 61223-2-6 standards.
Specifications
  • Energy Linearity: Outstanding energy linearity within 0.5% for radiation qualities ranging from 70–150 kV.
  • Effective Length: Precisely defined at 100 ±0.5 mm, allowing accurate dosimetry in wide beams.
  • Active Volume: 16 cm³
  • Effective Length: 300 mm
  • Diameter: 12 mm (12.6 mm including O-rings)
  • Typical Leakage: ±20 fA
  • Radiation Quality: 70 - 150 kV
  • Sensitivity: 30 mGycm/nC
  • Energy Dependence: ±1%
Compatibility
The chamber is compatible with Mako, Piranha, and Cobia systems, with specific part numbers for each.
Additional Features
  • Rubber O-rings ensure secure and precise placement in the CTDI phantom.
  • The optional LoniMover enhances positioning accuracy and efficiency.
Mako Ion Chamber Module
This module connects RTI Ion Chambers to the Mako System, featuring automatic temperature and pressure compensation. It allows connection with other brands of Ion Chambers as well.
Mako PI Dongle
The Mako PI Dongle is required for connecting Ion Chambers to the Mako Ion Chamber Module, containing calibration data for the Ion Chamber.

RTI CT Ion Chamber 30 cm-1

The RTI CT Ion Chamber 30 cm is a rugged, cylindrical, pencil-shaped vented ionization chamber designed for CTDI measurements. It is intended for measuring and monitoring the exposure output level of CT scanners, either in a phantom or free-in-air. CT Dose Index (CTDI) can be measured in accordance with IEC 61223-2-6. The RTI CT Ion Chamber offers outstanding energy linearity - within 0.5% - in the range 70-150 kV for the IEC 61267 radiation qualities RQR 5 to 10, RQA 5 to 10, RQT 8 to 10, and ISO N-150. With a precisely defined effective length (100 ±0.5 mm), the chamber enables accurate dosimetry in wide beams, even when repositioning is required. The optional LoniMover further enhances positioning accuracy and efficiency. Rubber O-rings provide secure and precise placement in the CTDI phantom. Connector type LEMO triaxial Cable 2 m, low noise triaxial Diameter 12 mm, 12.6 incl O-rings Specifications in this document may be changed without notice
