DiffPose will provide Anterior-posterior (AP) and lateral view 2D/3D registration method?

Hi Vivek,

Thank you for your work. I have test the DiffDRR, the registrations errors below! AP view registraion error

The erros of the dy is 4.49, because we only use the AP view to registration.

I have extend the DiffDRR registration to create AP view DRR and Lateral DRR.

The registations errors below!

That the errors of dy is 5.29mm.

Hi @BigPandaCPU , not sure where your issues is arising from. In general, failure of registration to converge is either due to

• A poor initial pose estimate
• Bad hyperparameters (especially too high learning rate for the optimizers)

Specifically for your misregistration, it doesn't look like the by is misestimated. Rather, I would expect gamma to be off, since the moving DRR is rotated relative to the fixed DRR.

Feel free to open a new issue (probably in the DiffDRR repo) if your issue persists.
