nabu.reconstruction.rings_cuda

source module nabu.reconstruction.rings_cuda

Classes

Functions

  • can_use_cuda_deringer — Check wether 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).
