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.
  • The print buttons at the upper left of the document preview window initiate either single document or document group printing and/or export as a .pdf file.
  • Option-click the Print Group button in the toolbar to automatically name and generate a .pdf file (or files) in the patient's treatment plan folder. You can automate the task of subdividing a treatment plan into multiple smaller parts for meeting email attachment requirements via settings in the Institution window.
  • The checkboxes below the document selection buttons at the top of the window indicate which documents will be included in group printing.
  • You can customize a document by clicking the Options button in the menu bar or by double-clicking in the middle of the document window.
