Diagnostic instrumental investigations based on the use of the ionizing radiation are on the rise and they urgently calls attention to the need to evaluate and monitor the absorbed dose over time by each patient, as indicated in the recent EURATOM/59/2013 directive. In particular, the EURATOM/59/2013 directive highlights the need to record and to communicate to patient the dosimetric information relating the radiological procedure. The computed tomography examinations are widely used, and in this case the evaluation of the absorbed dose in the individual organs is of particular importance. The evaluation of the organ dose is of high interest at both scientific and clinical levels, because the radiosensitivity depends by tissue and specific organ, in addition by subjective parameters, such as weight, gender and age of the patient; therefore a careful evaluation of organ dose requires a strictly individual analysis. This evaluation needs elaborate calculation systems and it can be carried out with the aid of Monte Carlo simulations that allow to determine the dose distribution in different districts, reproducing very well the ionizing radiations delivered. An overview of the commercial software packages currently used in the clinic for the evaluation of the organ dose during the computed tomography examinations will be given.


KEY WORDS: Radiation exposure - Drug dosage calculations - Computed tomography
