The Dose Area (or volume) Histogram can be a 1 to 4 page document.
- Plot #1 - By default, a cumulative dose-area histogram of the retinal surface. Use the Retina-Dose-Area Histogram (RDAH) to confirm dosimetric coverage (e.g. 85 Gy) of the tumor base (GTV) and tumor base + margin (PTV), and to find seed loading patterns that reduce dose to critical regions such as the macula and optic disc. A Dose-Volume Histogram (DVH) can also be calculated, but it is not very useful because the most critical regions of the eye are the retinal and choroidal layers which are better modeled by a surface area calculation.
- Plot #2 - By default a differential RDAH.
- Legends - if enabled, an expanded legend page for each printed histogram.
- Tables - if enabled, the raw binned data for each printed histogram in a tabular format. These data in expanded format can also be copied to the MacOS clipboard and/or exported as .tsv files from the edit menu when the document is being displayed.
