Computed Radiography

Computed radiography (CR) uses an imaging plate, instead of film. The imaging plate contains photostimulable storage phosphors, which retain the latent image. When the imaging plate is scanned with a laser beam in the digitizer, the latent image information is released as visible light. This light is captured and converted into a digital stream to compute the digital image.

A computed radiography reader scans the plate by means of a laser beam. The laser energy releases the trapped electrons, causing visible light to be emitted. This light is captured and converted into a digital bit stream that encodes the digital image.

Computed Radiography

Less Retakes

The storage phosphors on the Digital Imaging Plate have an extremely wide dynamic range. This gives a high tolerance for varying exposure conditions and a greater freedom in the selection of the exposure dose. As a consequence, the need for retakes is drastically reduced.
Dose Reduction

The wide exposure latitude of the Digital Imaging Plates allows, in many cases, the visualization of all diagnostic information with only one exposure. In this way, the use of Digital Imaging Plates results in a substantial reduction of the dose load.
Long Lifetime

Digital Imaging Plates are protected by an EBC (electron-beam-cured) topcoat, a proprietary technology for hardening a prepolymer lacquer coat into a high-density polymer on top of the phosphor layer. This results in plates with superb protection from mechanical wear and extensive immunity to chemical cleaning solutions. Superior durability of the Digital Imaging Plate is thus secured.
High Image Sharpness

The chemical composition of the Image Plate storage phosphor material ensures optimum performance. The material has high absorption efficiency, excellent homogeneity and short response time to ensure high sharpness and the EBC top coating technology provides a smoother plate surface giving reduced granularity noise.
