The demand for medical imaging examination is constantly growing, and safety, quality in radiological practice, human potential, training are more important than ever. Public awareness and concern about radiation safety has grown in the last few years, and concerns have been voiced about radiation dose, across a wide range of media. People are worried; they receive conflicting, sometimes confusing information, and they come to the radiology department with these concerns. Nowadays, things have changed in a very positive way: new software tools that can automatically retrieve, store and analyse dosimetric data are now available. These IT resources can be installed on hospital networks, and are in most cases web based, ensuring easy access to all authorized users. One of the major challenges faced by health providers today are a result of both technological and information changes. Dose monitoring software helps radiologists deliver the right dose, while still producing diagnostic quality images. By tracking patients' cumulative dose over time, they can take steps to prevent excessive medical radiation exposure.
