Summary
Physical deterioration of computed radiography (CR) cassettes and imaging plates (IPs) causes image artifacts. Regular quality control, including cleaning and inspection, is essential for CR equipment longevity.
Area of Science:
- Medical Imaging
- Radiography Technology
- Quality Control in Healthcare
Background:
- Image artifacts in computed radiography (CR) have been reported.
- The physical condition of CR cassettes and imaging plates (IPs) may contribute to these artifacts.
Purpose of the Study:
- To investigate the physical condition of CR cassettes and IPs in clinical use.
- To determine the relationship between physical deterioration and image artifacts.
- To assess the need for a quality control program for CR equipment.
Main Methods:
- Visual and radiographic examination of 197 Fuji, 35 Agfa, and 37 Kodak CR cassettes with IPs.
- Analysis of cassettes and IPs from four radiology departments.
Main Results:
- Extensive physical deterioration of CR cassettes and IPs was observed.
- Premature wear of cassettes and IPs was identified as a primary cause of image artifacts.
- The extent of deterioration was greater than previously assumed.
Conclusions:
- A comprehensive quality control program for CR cassettes and IPs is crucial.
- Regular cleaning and both visual and radiographic inspection are recommended.
- Implementing these measures can reduce image artifacts and extend CR equipment lifespan.
