nabu.reconstruction.rings_cuda

source module nabu.reconstruction.rings_cuda

Classes

Functions

  • can_use_cuda_deringer — Check whether the CUDA implementation of deringer can be used. Checking for installed modules is not enough, as for example pyvkfft can be installed without CUDA devices

source class CudaMunchDeringer(sigma, sinos_shape, levels=None, wname='db15', padding=None, padding_mode='edge', fft_backend='vkfft', cuda_options=None)

Bases : MunchDeringer

Initialize a "Munch Et Al" sinogram deringer with the Cuda backend. See References for more information.

Parameters

  • sigma : float — Standard deviation of the damping parameter. The higher value of sigma, the more important the filtering effect on the rings.

  • levels : int, optional — Number of wavelets decomposition levels. By default (None), the maximum number of decomposition levels is used.

  • wname : str, optional — Default is "db15" (Daubechies, 15 vanishing moments)

  • sinos_shape : tuple, optional — Shape of the sinogram (or sinograms stack).
