INTRODUCTION
The purpose of this study is to evaluate interfraction variations of two medical materials used for conventional pulmonary treatments in Tomotherapy. These are thermoplastic masks (TMP) and vacuum cushion (VC) system. METHODS The text develops a retrospective study of patients treated from 2014 to 2017 included, analyzes 30 patients using the thermoplastic mask and 30 patients using the vacuum cushion system. The location of the planning target volume (PTV) was determined by Image-Guided Radiation Therapy (IGRT) which will move the table before each treatment. The shifting accepted by medical imaging technologists were recorded in the axes vertical, longitudinal, and laterolateral. RESULTS As a result, mean displacements for the TMP and VC systems, respectively, were as follows: For the X axis, 2.27 mm vs. 2.07 mm; The Y axis, 3.54 mm vs 5.66mm and the Z axis, 1.36 mm vs 2.23 mm. CONCLUSION To conclude, the thermoplastic mask allows better positioning in the latero-lateral axis (X) and in the vertical axis (Z). And for a good positioning in the longitudinal axis we get better results with the vacuum bag. |
