Development of voxel based method for evaluation of the radiotherapy treatment plans: a novel approach

Radiotherapy treatment plans are evaluated by different methods i.e. slice by slice evaluation, DVH based evaluation and plan metrics methods etc. All the methods involves the three dimensional (3D) dose matrices which contain voxels having different information tagged with them. In this study, information of the location of voxel of different 3D dataset of computed tomography (CT) images, RT structures set and RT dose are used for the evaluation of the plan and further this approach is used for the radiobiological evaluation of the treatment plan
