ewokstomo.tasks.online.reconstruct_slice.fbp_reconstruction_slice(projections, angles, rotation_center, slice_index=None, halftomo=False, padding_mode='edges', extra_options=None)[source]#

Perform FBP reconstruction on a single slice.

Reconstructs only one horizontal slice from the projection stack, useful for quick preview or center of rotation determination.

Parameters#

projectionsnp.ndarray: Array of projections with shape (n_angles, n_z, n_x)
anglesnp.ndarray: Rotation angles in radians
rotation_centerfloat: Rotation axis position
slice_indexint, optional: Index of the slice to reconstruct. If None, uses the middle slice. Default is None.
halftomobool, optional: If True, assumes half-tomography acquisition. Default is False.
padding_modestr, optional: Padding mode for sinogram extension. Default is ‘edges’.
extra_optionsdict, optional: Additional options for the backprojector. Default is {‘centered_axis’: True}.
