  Purpose: The aim of this work is to investigate the dose verification of common conventional Intensity Modulated Radiation Therapy (IMRT) Quality Assurance (QA) performance metric using verisoft software. Based on Gamma index analysis we performed a comparison between 2D and 3D of the delivered and planed dose for complex geometry, Gamma index passing rate (GP%) is calculated using different criteria 3%/3 mm, 3%/2 mm and 2%/2mm dose difference/ distance-to-tolerance criteria (DD/DTA) to check the quality the plan before starting the treatment . Materials and methods: Ten complex Intensity Modulated Radiation Therapy (IMRT) (80 beams) plans for two different pathologies are calculated using the Eclipse Treatment Planning System (TPS), Pre-treatment verifications were performed for all patients plans by acquiring planar dose distributions of each ..
