Revision 1.7 of the TPPC Profile (Trial Implementation, updated 7/17/19) will be tested at the IHE-RO 2023 Connectathon.

The Treatment Planning - Plan Content (TPPC) 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.

Test participants are encouraged to view the TPPC Testing Guide.

• 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 H&N: x = -3.2mm, y = 69.2mm, z = 239 mm (DICOM)
  • Prone patient Pelvis: x = -2.7mm, y = 28.4mm, z = 254 mm (DICOM)
  • Brain mets patient: CT isocenter 1: x = 42.3mm, y = -194.3mm, z = -65.0mm; isocenter 2: x = -10.2mm, y = -256.8mm, z = -66.0mm (DICOM)
  • Brain mets patient: MR isocenter 1: x = 36.8mm, y = 17.9mm, z = 32.7mm; isocenter 2: x = -14.7mm, y = -45.7mm, z = 32.0mm (DICOM)
  • Spine Mets patient: CT Isocenter: x= 7mm, y= -200mm, z= -554.0mm (DICOM)
• Specify dose as follows:
  • Supine H&N a total dose of 54 Gy (27 x 2 Gy fractions) to ptv54
  • Prone Pelvis total dose of 45 Gy (25 x 1.8 Gy fractions) to PTV 45 GY
  • Brain Mets total dose of 22 Gy total to either or both PTVs
  • Spine Mets total dose of 27 Gy (3 x 9 Gy fractions) to CTV
• 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 TPPC Actor, i.e. beam type, that produced it.
• If possible, do not include setup beams in the plan.
• Calculate dose and display 20, 90, and 100% 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.)
• If possible, please add a dose reference point at isocenter.

Four patient datasets are available for testing TPPC Actors:

• TPPC23A01xx - Supine (head/neck) patient
• TPPC23A02xx - Prone (anal-canal) patient
• TPPC23A03xx - Multiple brain mets patient
• TPPC23A04xx - Spine mets patient

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

Note: the numbering below is different from the numbering used in the draft Supplement http://ihe-ro.org/lib/exe/fetch.php?media=doc:profiles:ihe-ro_tppc_v1.6.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. MLC Variable Aperture Arc Beam: Generate a plan with two lateral arcs (0 -270, 0 – 90)
8. MLC Fixed Aperture 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
10. Sliding window Beam: Generate 5 beams, use structure ptv18 as target
11. Static Electron Beam: Generate a plan with a 10 x 10 applicator, 110 SSD, 9 MeV energy. Normalize beam to 2cm deep on central axis, if possible. Add dose reference point at normalization point, if possible. Note: the isocenter is different than in other plans
12. IMAT/VMAT Beam: Generate a VMAT/IMAT plan, use structure ptv18 as target
13. Photon Applicator Beam: Generate a photon applicator (stereotactic) plan
14. Photon Applicator Arc Beam: Generate a photon applicator (stereotactic arc) plan
