Differential DVH
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.
