Paper Abstract

The comparative study on the image quality between Computed Radiography (CR) and digitized film radiograph has been carried out. We have successfully digitized a radiographic film of an aluminum step wedge, an ASTM and coins using a flatbed scanner. Then, a comparative study was developed using CR as a reference. We used 4 set-up variations of kV and mA. The image quality was assessed based on the visual analysis: brightness, sharpness, and contrast, and the physical information analysis. The results show that visually the image quality of CR was better to the digitized film radiographs. However, CR was unable to distinguish the physical information such as the effect of voltage or current and the object characteristic to the image quality.
