Computed radiography X-ray system

Computed radiography (CR) uses very similar equipment to conventional radiography except that in place of a film to create the image, an imaging plate (IP) made of photostimulable phosphor is used.Computed radiography provides correct optical density on film, independent of the incident radiation exposure, but it can result in under- or overexposure of the imaging plate.
Computed Radiography are used to diagnose diseases and locate broken bones or other malfunctions in the body. X-ray is a short electromagnetic ray that can penetrate tissues to varying degrees. And then I will introduce some CR models below:
PHILIPS Computed Radiography
Model: PCR Eleva CosimaX reader
Features:
The PCR Eleva CosimaX reader with its four slots feeding allows for throughput of up to 165 plates per hour. It is ideal for a central reader setup with multiple Eleva workspots. Its dual side reading of small imaging plates results in a 50% increase in DQE (Detective Quantum Efficiency). Therefore the PCR Eleva CosimaX is specially suited for low dose pediatrics and, combined with the 50 µm pixel size, also for high-resolution mammography
FUJIFILM Computed Radiography
Model:FCR CAPSULAX
Features:
Small enough to fit anywhere - footprint 0.22 m2, height 0.81 m
Easy operations viewed on small monitor
Supports various diagnostic imaging sizes (7 sizes including 15 x 30 cm)
As the name implies, CAPSULA, meaning small box in Latin, has been drastically trimmed to be smaller and lighter than ever. With FUJIFILM's revolutionary vertical cassette loading method, workspace is reduced compared to previous horizontal insertion models, with no compromise in speed or image quality.
FCR CAPSULA X processing 43-72 images per hour is optimal for remote or low volume areas with less demanding workflow.
