Hi, That's one solution. Two other: - graft the output to a Cuda image itk::CudaImage<float, 3>::Pointer cuImg = itk::CudaImage<float, 3>::New(); cuImg->Graft(projectionReader->GetOutput()) - use the rtk::ImportImageFilter which is templated over image type to allow precisely this (I used it in Gate here <https://github.com/OpenGATE/Gate/blob/develop/source/digits_hits/src/GateFixedForcedDetectionActor.cc#L1583> ). Best regards, Simon
