Thanks! With regards to your observations:
- I did the current angulation projection on purpose - I did have one at first like you suggested, but the way the module works is precisely replicating what we use in clinical practice for TAVI (
). See link here (https://www.sciencedirect.com/science/article/pii/S1936879814009236)That’s why the logic behind my implementation is getting all the angulations corresponding to all vectors perpendicular to the aortic plane - Automatically getting the hinge points would be a “Holy Grail” as it would fundamentally render the process fully automatic. I’m not aware of any software that does this, but all that it would take I suppose would be getting a lot of cases where we’ve had such measurements done. I have already thought of finding a way of exporting our current measurements in official leading software to 3D slicer to form a training base. If I find I way, a collaborative approach with other institutions could follow for validating it
- I have experimented with the MONAI and Total Segmentator. They’re very impressive, but even on a MacBook M3 Max with 64 Gb of RAM (what I’m running) seems pretty slow, as it takes a couple of minutes running the inference. Don’t know if that’s to be expected or not.
- I’ll be testing my module locally with fellow Structural Heart Operators to see how they feel about it and correct/find possible bugs. If they’re happy with it, I think it may make sense to either integrate it with a existing extension (like Heart Slicer or others) or provide an entirely new one.
I’ll keep in touch as I further develop this.
