Computed Radiography (CR) and Digital Radiography (DR) are two digital X-ray imaging technologies, each with distinct advantages and disadvantages.
| Aspect | Computed Radiography (CR) | Digital Radiography (DR) |
|---|---|---|
| Advantages | - Lower initial cost than DR | - Superior image quality and resolution |
| - Compatible with existing X-ray equipment | - Faster image acquisition and processing | |
| - Portable and flexible cassette size | - Lower radiation dose due to higher sensitivity | |
| - No need for chemical processing | - Immediate image availability | |
| Disadvantages | - Requires manual handling and cassette processing | - Higher initial investment cost |
| - Slower workflow due to image plate scanning | - Less flexible positioning due to fixed detectors | |
| - Image quality lower compared to DR | - Equipment components are expensive and sensitive | |
| - Image plates prone to wear and damage | - Less portable compared to CR, although wireless systems are improving portability |
