Balancing system performance and dose is an important Quality Assurance requirement best satisfied with the Wireless CR Radchex Meter. The Wireless CR Radchex Meter is a factory, radiation-calibrated and NIST traceable light meter that can be used to calibrate (balance) CR plate readers (also radiation-calibrated light meters) in the field.

Benefits
Using the Wireless CR Radchex Meter to calibrate x-ray system AEC and CR plate readers instead of a dosimeter can greatly improve productivity. A full system AEC and CR plate reader calibration process can take up to six hours to complete; whereas with the Wireless CR Radchex Meter, the process can be completed in under two hours. The Wireless CR Radchex Meter is designed to work with all major brands of CR equipment.
The Wireless CR Radchex Meter has the same x-ray energy response as a CR system (x-ray to light conversion efficiency is the same for various beam conditions), so it can be used as an accurate and precise replacement for the plate readers light measurement value (exposure index value). This meter can save valuable time when calibrating or accessing CR readers and AEC, and can be used with multiple x-ray systems. The size of the electronic cassette is the same as a standard CR cassette and can be placed in the Bucky tray for ‘In-Bucky’ or ‘table-top’ measurements.
Applications
The Wireless CR Radchex Meter is ideal for use by service engineers to initially calibrate the CR plate reader, AEC, and density selector settings. Radiology managers can use the Wireless CR Radchex Meter to assist in the establishment of technique charts and training to determine ALARA techniques for various exam types. Physicists use the Wireless CR Radchex Meter to assess the performance of CR-AEC for compliance to clinical system speed objectives and patient dose. QA personnel can use the Wireless CR Radchex Meter to periodically document the performance of the CR system and to compare CR to film/screen systems regarding desired ALARA objectives.
The Wireless CR Radchex Meter uses Bluetooth to communicate with a laptop or desktop computer so that the CRLU (CR Light Units), EI (Exposure Index) and estimated mR values measured by the electronic cassette are automatically recorded and displayed on the laptop screen.
