To reduce risk of cancer the radiologist has to reduce radiation dose.
X-ray imaging always involves a compromise between dose and diagnostic needs: as much dose as needed for optimal imaging, as little dose as possible.


Technological innovations have helped to reduce dose and still get a high quality image.
Constant technological innovation has resulted in a continually improved ratio between the size of the focal spot, the exposure time, and the dose.
Intelligent software not only makes automatic adjustments before scanning, but also enables the radiologist to use individual doses which results in reduced dose.
Automatic adjustments to the clinical questions and the patient's anatomy through software enables the use of individually adapted doses.
