Summary

Computed tomography represents the mainstay for diagnosing various diseases in the whole body. Over the past decade, enormous efforts were undertaken by both CT manufacturers and radiologist to reduce the radiation dose to patients. Today, the dose is significantly lower that it was before the era of multislice CT and iterative reconstruction methods. The X-ray beam originating from the tube in a CT system contains a spectrum of different energies, whereby the "harder" beams with higher energy penetrate the patient better, and the "softer" beams will be absorbed through the patient's tissues. Recent research has been shown that the radiation dose can be further reduced by improved primary beam filtering in CT. This study is intended to compare the radiation dose in clinically indicated, routine CT examination while maintaining a diagnostic image quality, on a new CT system with modified primary beam filtering.
