Several digital systems are currently available for the acquisition of projection
radiographs. Digital radiography systems have been replacing traditional analogue
or screen–film (SF) systems over the last three decades. The transition from an SF
environment to a new digital environment should be considered as a complex
process. Technical factors concerning image acquisition, management of patient
dose, and diagnostic image quality are some issues that could influence this process.
In a transition process from SF to digital, patient radiation doses could increase
40–103% [1]. When compared to SF, digital technology could increase patient
radiation doses due to the wide dynamic range they have. However, the dynamic
range is useful because it contributes for a better clinical image quality when
compared to traditional SF systems [2]. This is an important difference among
