    Dosimetric evaluation of patient setup errors due to uncertainties during IMRT for head and neck cancer cases
    Author(s): Marwa Abdel Razek*, Khaled Elshahat, Ehab Khalil and Wafaa Khalil

    Background: IMRT become popular because dose escalation to the target can be done while sparing adjacent normal tissues. Intensity-modulated radiation therapy tends to produce steep absorbed-dose gradients between the target volume and the OAR. This study was done to determine the error during RT on positioning displacement for patients treated for head and neck cancer. We tried to find the magnitude of daily setup errors to determine the set up error cases. The results can help physicians to determine the most suitable margin for head and neck cases. Results: Data from 20 patients calculated. The Right/Left direction as X direction, Anterior/Posterior direction as Y shift and Up/Down direction as Z shift. Average shift for all fractions calculated to be 0.05 cm, 0.08 cm and -0.02 cm as RT/LT, Ant/Post and Up/Down shifts. Conclusions: To reduce setup errors in patients with H&N ca.. Read More»
