  1. Evaluation of Intensity Modulated Radiation Therapy (Imrt) Delivery Error Due to Imrt Treatment Plan Complexity and Improperly Matched Dosimetry Data

    Tonigan, Jacqueline R2011

    <p>Intensity modulated radiation therapy (IMRT) is a technique that delivers a highly conformal dose distribution to a target volume while attempting to maximally spare the surrounding normal tissues. IMRT is a common treatment modality used for treating head and neck (H&N) cancers, and the …
