--- This research aims to reduce absorbed dose of patients in clinical examinations using diagnostic X-ray, based on the results of the evaluation of each parameters that modify the X-ray spectrum. This study analyzes how to modify the X-ray spectrum with the variation of the following factors: tube potential (kVp), filtration and current multiplied by time (mAs). First, we determine the discrete and continuous X-ray spectrum using a computer simulation, this program that we use to calculate X-ray intensity is founded on the theory of Birch and Marshall. Moreover, from input data as values of tube potential, filtration, tube current, anode angle and a factor for energy, also with the program response (average energy and photon fluence), we analyze kerma reduction in the proposed techniques. We managed to reduce absorbed dose or kerma until 56,69 % in radiographic examinations. Besides this, we are studying the feasibility of implementing alternatively the use of tantalum filters in order to reduce absorbed dose of patients. The advantage of this methodology is that it is possible to optimize as well as implement new radiological techniques, which significantly reduce the absorbed dose. Therefore, guaranteeing the quality and safety in X-ray diagnostic procedures.
