Thorax Direct Digital Radiography is an easy and fast way to study this part of the body with the application of low doses to the patients. As it is a recent technique, there is not enough knowledge about the optimal levels of image quali-ty and dose

In the scope of the optimization of patient protection process (ALARA concept), the assessment of the patient radiation dose is not enough; image quality must be taken into consideration. The aim of this work is double: 1- to assess the image quality
