TPSs that work with DVHA

[cutright]

I just wanted to create a common location to document known TPS and versions that work with DVHA. If you've used DVHA and don't see your TPS and version on here, kindly add a comment. Below is a list off the top of my head.

• BrainLab iPlan 4.5
• Elekta Monaco 5.0
• Elekta XiO (version unknown)
• Philips Pinnacle 8.0m - 9.10, 16.2
• RaySearch RayStation 5.0 - 6.1
• Varian Eclipse 11 and 15
• MiM [not a TPS (yet?), but their DICOM files work too]
• VariSeed 9.0

Elekta Xio 4.34.02

The above version is about 10 years old.

For context, my facility is a particle beam therapy treatment centre. Our TPS is customized for particle beams (apparently back there were few TPSs that could handle particle beams). According to the medical physicists here, that customization meant that they couldn't export plans directly to DICOM; they created dummy photon beams with the same dose distributions and exported those.

Newer versions probably have updated DICOM export capabilities.

I plan to add Brachytherapy support by v0.8.0 (if it doesn't work already?). The previous web-based version worked, but I haven't tested since the wxPython rewrite.

The latest commit now supports brachytherapy plans from Eclipse 11 (or is it called Brachy Vision? Obviously I’m not a brachy guy).

Functionality needs to be added to ignore dose inside applicators/needles for brachytherapy.

What about the brachy plans on Oncentra? Could it be supported in the future?

[cutright]

Give it a shot. I tried it a couple years ago on a previous version and it worked OK. I only had to change one line of code to get Brachy Vision to work, so if it fails just send me terminal output.

On a related note... I'm certain there are some reasonably achievable add-ons to DVHA that brachy users would be interested in. I have a couple brachytherapy physicists in my clinic that are interested and plan to start using DVHA soon... but I am not clinically involved enough with HDR to know what sort of data is interesting.

Let me know what's missing?

I tried to import an Oncentra brachy plan. But the program was frozen. Here is the plan. It might be useful to use DVHA to evaluate a new plan by comparing with the historical plans in the database. But the difficulty of a plan depends not just on the distances between the CTV and the OARs. It also depends on the limitation of the applicator placement and relative position between the applicator, the target, and the OARs.

I did not observe a freeze. I was able to import these files, although it's not acknowledging the PTV to calculate PTV distances. I realize there's no "PTV" here, but if I label it as one, it should to the extra calculations... which should be a work around until I add GTV and CTV distance calculation funtionality.

[albertelonjobs]

Right. There is no PTV, which is typical for brachytherapy because there is no setup uncertainties. What you see is what you get. This is one of the advantages of brachytherapy. I'm wondering if the system can be tricked by considering a brachy CTV as a PTV for external beams.
I was able to import the files today too. I don't know what caused the freeze of the program. Anyway, it's working now. I'm very excited.

[albertelonjobs]

I tried to trick the system by defining the CTV as an alias of PTV. The plan, RT structure file, and the dose file have been imported with no error or warning messages. But the dose and the structure volume were all empty when I checked it in the database administrator.

Hello Dan, thanks for the DVHAnalytics project you share with us!
I just came across it and tried to use it but was not able to load data from Monaco v. 5.11.03.
I am sending you some simple phantom data that I created to see if their is an actual issue with the specific Monaco version or if it something else that I did wrong. I also have a print screen of the error message I got which will hopefully help.

Thanks for sharing. Should be an easy fix. It brings up two issues:

• DVHA should not crash if a tag is not found
• Monaco 5.11.03 (at least) stores SoftwareVersions (0018, 1020):
  • in the RT Dose, but DVHA currently checks the RT Plan
  • as a string rather than a list of strings

I'll push a fix to a dev branch today. Based on your screen shot, I'm guessing you installed via pip?
