Background
The revolution in the health sector is developing very rapidly and is constantly producing new innovations that have various benefits in the world of health, one example is in the Radiology unit. The output results in a radiological examination are radiographs. The factors that used to evaluate the quality of a radiograph to produce an optimal image include a density, contrast, sharpness and detail. Computed radiography (CR) is one of the modalities which integrated with a computerized system that is widely used in the field of radiology unit today. One of the devices in a CR system that can function in issuing the output form in the form of a radiograph is a CR laser printer using a dry film. Using a dry film along with a CR laser printer must be reviewed because of the high costs of equipment and maintenance. At present re-developed ink-jet film whose image output process can use an ink-jet printer at a lower cost than using a dry film laser printer. studies about the quality of the radiograph for the differences between ink-jet film with dry film radiography is not yet known before.
Aims
To determine the difference in radiographic of the density value by using ink-jet film and dry-film computed radiography (CR), and to analysed the value of a more optimal density.
Methods
This Research uses quantitative analytic research with an experimental approach. Statistical analysis is a paired t-test if the data is normally distributed, but if the data is not normally distributed it will use the Wilcoxon test.
Result
The statistical test using Wilcoxon shows that the p-value is 0,000 whose indicates that H0 is rejected and Ha is accepted, which means there is a difference of density values between dry Film CR and ink-jet film. Dry film shows the optimal density results seen from the mean rank higher than the ink-jet film.
Conclusion
There is a difference of the density value between dry film CR and ink-jet film, where the optimal density value is indicated by dry film CR.
