Long period accuracy and reproducibility of MLC leaves position acquired in a daily QA program using EPID images

      Introduction: We present the analysis of the EPID images acquired during the last two years as a part of the daily MLC QA program of two linear accelerators. These images have been used to assess qualitatively MLC leaves position by a visual evaluation of the displacement between recorded and expected leaves positions. Specifically developed analysis SW allows evaluating from the images the accuracy and reproducibility of each leaf position.
