[Rtk-users] rtkfdk doesn't work correctly after a recent update

[Yang K Park]

Hi Simon,

 

Thanks for the advice. The current RTK was compiled with FFTW to use the phase extraction feature from Amsterdam shroud.

 

Regarding your suggestions,

 

1)      rtkramp w/ or w/o CUDA:

(command line: “ rtkramp --path projPath --regexp .*.his --hardware cuda --output Ramp_wCUDA.mha” )

 

Then, I have encountered following error.

“CudaFFTRampImageFilter<..> CudaFFTConvolutionImageFilter assumes that input requested and buffered regions are equal.”

 



 

Without CUDA, it was successfully done.

 

2)      I’ve re-compiled ITK w/o FFTW and built RTK again. rtkfdk worked fine.

-          I’ve also repeated “rtkramp+CUDA” with this rtk version and the error was same as above.

 

In conclusion, my FFTW seems to affect CUDA-based fdk reconstruction only.

But I do need FFTW for the phase extraction. What should I do?

 

Thanks.

 

Yang

Hi,

I didn't manage to reproduce the two problems on linux with the same ITK version.

For point 1, did you copy itkMacro.h by hand? Because I don't see how replacing <itkMacro.h> by "itkMacro.h" can help if itkMacro.h is not in the same folder as rtkCudaUtilities.hcu For point 2, no clue. Do you use FFTW? It looks like a ramp filter issue. Can you try rtkramp --path projPath --regexp .*.his, with and without --hardware cuda? Maybe you can provide your geometry file in case it's a specific geometric issue.
