IHE Radiation Oncology - ARTI Profile Testing

The Advanced RT Integration (ARTI) Profile is tested by importing CT image and Structure Set test data in a Producer Actor, creating a treatment plan (and dose) for a supported beam type, and exporting the plan (and dose) to an Archive for retrieval by a test partner (Consumer Actor). Side-by-side comparison of plan displays on the Producer and Consumer Actors is used to verify interoperable exchange of plan information.

General Instructions

  • Import and save CT images and RT structure set for both supine and prone patients. Import the multiple brain mets patient if you are testing stereotactic beams.
  • For each producer, create two plans, one with all supported options and one without options (if you support multiple options e.g.: beam limiting devices, bolus etc.)
  • Place isocenter as follows:
    • Supine patient: x = -3.2mm, y = 69.2mm, z = 239 mm (DICOM)
    • Prone patient: x = -2.7mm, y = 28.4mm, z = 254 mm (DICOM)
    • Brain mets patient: isocenter 1: x = 42.4mm, y = -194.3mm, z = -65.0mm; isocenter 2: x = -10.2mm, y = -256.8mm, z = -66.0mm (DICOM)
  • Specify a total dose of 54 Gy (27 x 2 Gy fractions) to ptv54, unless otherwise specified.
  • Label the plan appropriately: e.g., plan_static_mlc
  • If possible, store each plan and dose in its own DICOM Series and use the Series Description to identify the ARTI Actor, i.e. beam type, that produced it.
  • If possible, do not include setup beams in the plan.
  • Calculate dose and display 20, 50, and 90% isodoses (normalize to the maximum dose).
  • Label the dose to correspond to the plan, e.g., dose_conformal_arc.
  • Please use the prone patient for at least 20% of your plans (at least one, if more than one beam type is tested).
  • Although it is not a Profile requirement, consider making the testing more interesting by creating a plan using a foot-first treatment position. (The CT images are head-first scans.)

Test Datasets

Three patient datasets are available for testing ARTI Actors:

  • ARTI15A01xx - Supine (head/neck) patient
  • ARTI15A02xx - Prone (anal-canal) patient
  • ARTI15A03xx - Multiple brain mets patient (for stereotactic beams)

Note: xx is a vendor code for the Producer Actor.

Supine patient Prone patient Multiple-metastases patient

Plans

Note: the numbering below is different from the numbering used in the Supplement ftp://ftp.ihe.net/RadiationOncology/Supplements/ARTI/IHE-RO_ARTI_Supplement_V1-6_2014-02-25.docx

  1. Basic Static Beam: Generate a plan with two opposing lateral beams
  2. Basic Static MLC Beam: Generate a plan with two opposing lateral beams
  3. Motorized Wedge Beam: Generate a plan with AP and right lateral beams
  4. Hard Wedge Beam: Generate a plan with AP and right lateral beams
  5. Virtual Wedge Beam: Generate a plan with AP and right lateral beams
  6. Arc Beam: Generate a plan with two lateral arcs (0 -270, 0 – 90)
  7. Conformal Arc: Generate a plan with two lateral arcs (0 -270, 0 – 90)
  8. MLC Arc Beam: Generate a plan with two lateral arcs (0 -270, 0 – 90)
  9. Step & Shoot Beam: Generate 5 beams, use structure ptv18 as target
