Medical DR (Digital Radiography) and CR (Computed Radiography) are two different medical imaging technologies, which are different in imaging principle, image quality, exposure dose, and workflow.
1. ** Imaging principle ** :
- **CR** : IP plate (imaging plate) is used to record X-ray image information. IP board after the exposure of store image information, and then through the scanner and converted into digital image.
DR * * - * * : use the flat panel detector (FPD) directly to the X-ray image is converted to digital signals. This way is more direct and efficient.
2. ** Image quality ** :
The image resolution of - **CR** is affected by scattering and may appear blurred.
- **DR** provides higher image resolution and sharper images because it is not affected by optical blur.
3. The exposure dose of * * * * :
CR - * * * * relative to DR need higher exposure dose, because of its conversion rate is low.
4. * * * * workflow:
CR - * * * * process is relatively complicated, need to remove the IP board to read when exposed to light.
- **DR** images are obtained almost immediately after exposure, making the process more rapid and efficient.
5. * * * * network integration:
- **DR** technology has better network integration characteristics, which can be more easily integrated with the hospital's information system.
Overall, the DR Technique is superior to the CR technique in several aspects, including faster imaging speed, higher image quality, and lower exposure dose. As a result, the DR system is more widely used in the field of medical imaging. However, CR system still has its application value in some specific circumstances, especially in some small and medium-sized hospitals.
