Wireless CR RADCHEX and QA RADCHEX Technical Data The wireless 07-CRXW CR RADCHEX and 07-QRX QA RADCHEX are factory radiation-calibrated, NISTtraceable light meters that can be used to calibrate (balance) CR plate readers (also radiation-calibrated light meters) in the field. The CR plate reader in the field will be calibrated and traceable to the Fluke Biomedical factory radiation-calibrated and traceable x-ray-produced light exposure. Both 07-CRXW and 07-QRX have the same x-ray energy response as a CR system (x-ray-to-light conversion efficiency is the same for various beam conditions). This enables them to be used as accurate and precise replacements for the plate reader’s light measurement value (exposure index value). Most importantly, the 07-CRXW and 07-QRX can save valuable time when calibrating or accessing CR readers and AEC used with multiple x-ray systems. These x-ray systems may have different filtration and beam characteristics even when located in the same department or imaging center. Balancing system performance and dose is an important QA requirement best satisfied with either the 07-CRXW or 07-QRX. • Calibrates computed radiography (CR) plate readers and automatic exposure control (AEC) • Assesses ongoing performance of CR plate reader, AEC, and automatic programmed radiography (APR) • Sets and maintains desired clinical system speed (dose) of the CR system • Calibrates CR plate readers in the field to be traceable to a factory radiation-produced light condition Links radiation exposure (mR) to the front of the plate accurately and • predictably to a CR light measurement value (CRLU) Provides a reliable and reproducible method of accurately maintaining • a CR manufacturers’ specific factory calibration Provides three different tube-head filtration choices for users who desire • a non-filtered beam condition for field plate reader calibration • Software selections of multiple beam conditions for different CR manufacturers • Ideal tools for service engineers, physicists, and quality assurance personnel

Applications 07-CRXW CR RADCHEX The wireless 07-CRXW is ideal for use by service engineers to initially calibrate and troubleshoot the CR plate reader, AEC, and density selector settings. Physicists use 07-CRXW to assess the performance of CR-AEC for compliance to clinical system speed objectives and patient dose. Radiology managers can use 07-CRXW to assist in the establishment of technique charts and training to determine ALARA techniques for various exam types. QA personnel can use 07-CRXW to periodically document the performance of the CR system and to compare CR to film/screen systems...
