Webevaluate dose homogeneity within a target volume. Materials and Methods: The new HI is based on the area under an ideal dose‐vol-ume histogram curve (IA), the area under the achieved dose‐volume histogram curve (AA), and the overlapping area between the IA and AA (OA). It is defined as the ratio of the square of OA to the product of the IA ... Web2024) with applications in radiation oncology. It provides functionality to read dose-volume-histogram (DVH) text files, to calculate DVH metrics, and to plot DVHs. In addition, it checks and visualizes quality assurance constraints for the DVH.2 To install DVHmetrics, you need a current version of R and be online.

WebA histogram is a chart that plots the distribution of a numeric variable’s values as a series of bars. Each bar typically covers a range of numeric values called a bin or class; a bar’s height indicates the frequency of data points with a value within the corresponding bin. The histogram above shows a frequency distribution for time to ... Web31 mar 2024 · A voxel-based approach for dose determination with a more refined dose calculation model, such as a convolution-based method for instance, could have been useful in this case to characterize the limits of this approach. A dose-volume histogram would have been also very useful to determine more accurately the dose distribution. WebAbstract. In radiation therapy, a secondary independent dose verification is an important component of a quality control system. Mobius3D calculates three-dimensional (3D) patient dose using reference beam data and a collapsed cone convolution algorithm and analyzes dose-volume histogram automatically.
