Towards patient dose optimization in digital radiography

Digital radiographic imaging systems cover a wide range of clinical applications and can produce adequate image quality using a broad span of exposure levels. Over exposure may generate higher dose levels without an affective increasing of the images quality; thus experimental data analysis is an ongoing process useful to provide information about adequacy of radiation exposure. The main purpose of this work is the assessment of quality performance of digital radiographic systems by using objective image quality tests. To this aim, the influence of radiographic parameters has been investigated in order to reduce radiation dose to patients by assuring a good quality of the images.
