  Purpose: Patients movement and Organs mobility during Three Dimensional Conformational Radiotherapy (3D-CRT) may introduce errors especially during the treatment delivery, random and systematic errors are one of the most accurate errors. In this work we implanted a method to determinate the Clinical Target Volume (CTV) to Planning Target Volume (PTV) margins. The aim of this study is to reduce these errors probability by the evaluation of the optimal for CTV-PTV margin by studying the corrected values of deviations for HNC at the Mohammed VI cancer treatment centre treated between 2019 and 2021. Material and Method: The study consists on creating a DATA base containing spatial movement of study group of 100 patients following the treatment machine axis Vrt, Lng, and Lat directions during the first four fractions.
