This section is intended to provide access to previous versions of the decimal ElectronRT (eRT) documentation. Below you will find the userguide for each released version of the decimal eRT app. To find your application's current version use the top “View” menu and select “App Info”; the “Version” field will contain your current version of the App.

User Guide information is directly available on this website for the current latest release and PDF files are provided for offline user guide access for all application versions below.

July 25, 2022 - Download decimal eRT 0.9.0 User Guide

(Note: The changes to this version did not result in a User Guide update, so the previous version (0.9.0) of the User Guide is used for this release)

What's New

• Updated plan import to not require bolus selection when the plan has no bolus
• Updated plan import to allow the user to select applicator(s) when import validation fails
• Implemented corrections for IM Dose calculations to account for the presence of the IM foam and scatter in/out of the IM pins (corrections based on MBPCC provided data and will be validated at a later stage before clinical release)

Bug Fixes

• Corrected several bugs where user provided commissioning data was overridden with calculated values. Note users will need to reimport their commissioning data for these corrections to be applied.

Note: This release has not been cleared by the FDA for clinical use

May 27, 2021 - Download decimal eRT 0.0.4 User Guide

What's New

• Adds plan level prescriptions and dose normalization.
  • Note 1: This version removes the prescription definition from the patient Course.
  • Note 2: Unapproved treatment plans created in versions earlier than eRT version 0.0.4 will not have the plan prescription filled in (denoted by the error: “Prescription statement not found in plan”) resulting in dose not being displayed within the treatment plan displays. Users can resolve this by re-adding the prescription that previously existed in the corresponding Course [Known Limitation: Approved Plans #2].
• Adds beam normalization options when creating or editing a beam.
  • Users can choose from normalizing to a point, structure (min, mean, or volume), or isodose line.
• Adds automatic skin collimator thickness and the option to override and provide a manual thickness.
• Combined the Electron Block and Skin Collimator blocks into a single Collimation Block when defining a beam. This ensures the Electron Block and Collimator are correctly constrained to each other's geometries for best planning results.
• Adds the DICOM receiver as a configurable and extractable package to the DICOM Organization Configuration block.
• Adds a DICOM AE server echo test to the DICOM Organization Configuration block.
• Adds a CSV import/export for CT curves in the Organization Configuration block.

Bug Fixes

• Fixes a bug preventing the user from importing only a RT Structure Set into an existing patient.

• Fixes dose appearing on top of bolus and skin collimator devices by moving the draw order such that the dose image is drawn behind the device.
• Fixes DICOM RT Plan export issues including:
  • Missing RTBeam ApplicatorSequence
  • Missing RTBeam TreatmentDeliveryType
  • Missing RTBeam NominalBeamEnergy
  • Missing RTBlock BlockTrasmission
• Fixes non DICOM files being added to the import file list (they were not attempted to be imported, but it was ambiguous).
• Disables IM devices for Siemens 4×4 applicators.
• Fixes slow bolus operator calculations when compared to p.d.
• Fixes multiple beams causing an image unit error when attempting to export DICOM files.
• Disables the Beams and Export block if a CT curve is not selected (if there are multiple).
• Fixes the DICOM AE exporting locking the UI for a long duration.
• Fixes a bug allowing DICOM files for multiple patients on import.
• Fixes incredibly high dose outside of the patient body.
