Abstract

Computed radiography (CR) based on storage phosphor (SP) detector is a new and complex technology for obtaining medical digital imaging. The CR system was developed such that its image quality in diagnosis (wide latitude, certainty of visual diagnosis), speed (image sensitivity), image processing, and the overall imaging performance exceeds or at least equals those of the conventional screen-film (SF) radiography systems which are considered to be `gold standard.' The unique capability of the CR system places a new responsibility on the medical physicist, radiologist, and radiologic technologist to ensure that the digital images give the same information at least as film, and improve rather than degrade the image. For that reason the quality of the image must be ensured and each component of the system must function properly. The clinical knowledge about quality control (QC) and the standard procedures for CR devices have not yet been established and are still under development. This paper presents the acceptance/QC of the CR image reader and laser imager. The procedure includes the acceptance of the equipment for its image quality, image sensitivity, and overall imaging performance. The procedures are currently and routinely being utilized in our institution.
