Which digital imaging system is commonly used by limited operators today?

Computed radiography (CR) is commonly used by limited operators today due to its accessibility and ease of use. CR systems utilize photostimulable phosphor (PSP) plates that can be reused multiple times, making them cost-effective for facilities with varying patient volumes. The plates are placed in a reader machine, which scans and converts the stored energy into digital images, allowing for quick image acquisition and storage.

This technology typically doesn't require extensive training for operators compared to direct radiography (DR) systems, which involve more sophisticated digital detectors and potentially higher technical expertise for setup and calibration. Furthermore, CR can be easily integrated into existing radiographic systems, making it a popular choice for facilities transitioning from film-based to digital imaging.

While analog radiography is less common in modern practice due to the limitations of film-based systems, and digital subtraction angiography is specialized for vascular imaging, CR strikes a balance between efficiency and user-friendliness, particularly for limited operators who may not have specialized training in the more complex DR systems.
