IHE Radiation Oncology - TPPC Profile Testing
Revision 1.7 of the TPPC Profile (Trial Implementation, updated 7/17/19) will be tested at the IHE-RO 2022 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.
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 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 22Gy total to either or both PTVs
- Spine Mets total dose of 27Gy (3 x 9Gy 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.
Test Datasets
Four patient datasets are available for testing TPPC Actors:
- TPPC22A01xx - Supine (head/neck) patient
- TPPC22A02xx - Prone (anal-canal) patient
- TPPC22A03xx - Multiple brain mets patient
- TPPC22A04xx - Spine mets patient
Note: xx is a vendor code for the Producer Actor.
Plans
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|
- Basic Static Beam: Generate a plan with two opposing lateral beams
- Basic Static MLC Beam: Generate a plan with two opposing lateral beams
- Motorized Wedge Beam: Generate a plan with AP and right lateral beams
- Hard Wedge Beam: Generate a plan with AP and right lateral beams
- Virtual Wedge Beam: Generate a plan with AP and right lateral beams
- Arc Beam: Generate a plan with two lateral arcs (0 -270, 0 – 90)
- MLC Variable Aperture Arc Beam: Generate a plan with two lateral arcs (0 -270, 0 – 90)
- MLC Fixed Aperture Arc Beam: Generate a plan with two lateral arcs (0 -270, 0 – 90)
- Step & Shoot Beam: Generate 5 beams, use structure ptv18 as target
- Sliding window Beam: Generate 5 beams, use structure ptv18 as target
- 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
- IMAT/VMAT Beam: Generate a VMAT/IMAT plan, use structure ptv18 as target
