Radiotherapy has become one of the widely used modalities for treatment in an oncology setting, independent of whether the approach to treat cancer is either curative or palliative. As the technology evolved, we have incorporated many developments in cancer care radiotherapy treatment in day today life. It’s well known that Intensity Modulated Radiotherapy (IMRT) is superiorly suited to most of the cases than 3Dimensional Conformal Radiotherapy (3D CRT). Since IMRT uses Multi Leaf Collimators (MLC) to deliver non-Uniform Intensity modulated beams. This is achieved with the help of Inverse planning treatment planning system available. Though 3D CRT also implements MLCs for delivery, it has limitations of fixing to the regular equivalent Field sizes, where unnecessary dose being delivered to normal structures or critical structures also. There is also possibilities of secondary malignancy development when unnecessary dose deposited other than Planning Target Volumes. Intensity modulated beams not only avoids critical structures but also vary the dose range called as Simultaneous Integrated Boost. This significant effect can be seen on the patient’s quality of life even after cure of disease. An IMRT treatment plan though needs to be dosimetrically analyzed via, Patient specific Quality Assurance by both Point dose measurement and Fluence Verification.
