CTDI CTwater Phantom

Water-equivalent dosimetry phantoms for CTDI evaluation in Computed Tomography (CT/CBCT)

For CTDI measurements in accordance with IEC / DIN EN 61223-3-5 and IEC 60601-2-44
Different adapter plugs available for diverse pencil shaped ion chambers

Water-equivalent dosimetry phantoms, traced back on the standards for CTDI evaluation in Computed Tomography (CT/CBCT).

The phantom is manufactured from CTwater, a proprietary resin which exhibits the same X-ray attenuation characteristics as liquid water in the range of 80 kV to 140 kV tube voltage.

The phantom includes a circular body (with four peripheral holes) and a removable head section (with one central and four peripheral holes). Holes not in use for dose measurement can be plugged by using water-equivalent rods.

Adapter plugs for all standard ionization chambers are available on request.
