Series: Practical Evaluation of Clinical Image Quality (2): Image Quality Measurements for Digital Radiography Systems.

In recent years, the manuals and data analysis tools to evaluate the basic imaging properties of medical imaging systems, such as digital radiography system, CT, and MRI, are easily available. For the image quality evaluation of digital radiography systems, special measurement system, such as a microdensitometer, required for the analysis of analog radiography system, is not needed. This enabled anyone to perform the evaluation of digital radiography system.On the other hand, to make accurate measurements, obtaining appropriate image data is a must. To enable this, appropriate setting of the hardware and the software is also required. In addition, we are asked to acquire sufficient knowledge to make highly reproducible measurements.
