Dear Cyril, Thanks a lot. Now rtkramp.exe works with cuda option. I am trying to integrate rtk cuda ramp filter into my recon program. I read the projections with ProjectionsReader and pass image pointer to cuda ramp filter pipeline using cudaRampFilter->SetInput(projections);
I am getting runtime error and it says Error during cuda ramp filtering :: D:/programming/cpp/ext_libs/rtk_1_2/src/code/rtkCudaFFTConvolutionImageFilter.cu :97: itk::ERROR: CUFFT ERROR #2 Do I need to enable or disable any parameter while reading projections to get rid of this error? I changed rtk_proj_reader_->Update to rtk_proj_reader_->UpdateOutputInformation(); But I am still getting the error. The error exists only with CudaFFTRampImageFilter and FFTRampImageFilter works fine.
