The head and neck is a challenging anatomical site for intensity-modulated radiation therapy (IMRT). Dose distribution of difference field sizes were measured in a semi cylindrical phantom and a flat slab solid water phantom using a 2D array pixel ionization chambers I'mRT MatriXX. Dose verification in 2-dimension was performed on three nasopharyngeal carcinoma (NPC) IMRT plans by comparing measured I'mRT MatriXX dose distributions to treatment planning system calculated dose. A good agreement was found between I'mRT MatriXX measurements and TPS predictions for all the examined plans (γ-index <1 for 93% of pixels) with a maximum difference between both the phantoms being within 3%.
