Innovative German-made X-Ray Quality Assurance Solutions, X-Ray Quality Control and Radiation Protection Products


Advanced Pencil Chamber CT Meter

The QUART didoCT meter is designed for easy and precise dose-width product measurements. Its innovative detector features ionisation as well as solid-state technology.

The didoCT is also the first pencil chamber meter with the ability to measure HVL directly in the same exposure as the DLP (didoCT+ version).

The didoCT is equipped with a backlit display to assure swift readings even in darkened environments.

To provide the ability to track generator characteristics, the dose or DLP rate is refreshed continuously on the meter display while the measurement is running.

Special Feature - Direct CT-HVL Measurement

As an optional feature, the QUART didoCT can be ordered with free-in-air direct HVL measurement capability.

The meter‘s HVL feature is designed to easily measure the aluminium equivalent for a wide range of CT imaging equipment. It is calibrated at suitable standard radiation qualities in accordance with the majority of computed tomographs used in radiology
or radiation therapy.
