projection(projection_idx) → numpy.ndarray[source]
projection_angles(max_angle: float = 360.0) → mantidimaging.core.utility.data_containers.ProjectionAngles[source]

Return projection angles, in priority order: - From a log - From the manually loaded file with a list of angles - Automatically generated with equidistant step

Parameters

max_angle – The maximum angle up to which the angles will be generated. Only used when the angles are generated, if they are provided via a log or a file the argument will be ignored.

property projections
real_projection_angles() → Optional[mantidimaging.core.utility.data_containers.ProjectionAngles][source]

Return only the projection angles that are from a log file or have been manually loaded. :return: Real projection angles if they were found, None otherwise.

sino(slice_idx) → numpy.ndarray[source]
sino_as_image_stack(index) → mantidimaging.core.data.imagestack.ImageStack[source]

A single sinogram slice as an ImageStack in projection ordering

property sinograms
slice_as_array(index) → numpy.ndarray[source]
slice_as_image_stack(index) → mantidimaging.core.data.imagestack.ImageStack[source]

A slice, either projection or sinogram depending on current ordering
