In radiation therapy for cancer, differential (or direct) dose volume histogram (differential DVH) is a method for summarizing the radiation dosage of a treatment plan, one of two standard types of dose-volume histogram. It has the form of a generic histogram and displays the volume (or the percentage of the volume of total organ) plotted as a function of the dose within a specified bin. It reads like the volume of the organ that receives the dose of the correspondent dose - bin. It is built by the sum of the number of voxels characterized by a specified range of dosage for the organ considered. It is helpful in providing information about changes in dose within the structure considered and to easily visualize minimum and maximum dose. ==References==
