property data: ndarray

property dtype

property filenames: List[str] | None

property h_middle: float

Returns the horizontal middle (middle column) of the projections

has_proj180deg()

property height

property id: UUID

property is_processed: bool

Returns:

True if any of the data has been processed, False otherwise.

property is_sinograms: bool

property proj180deg: ImageStack | None

projection(projection_idx) → ndarray

projection_angles(max_angle: float = 360.0) → ProjectionAngles

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() → ProjectionAngles | None

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.

set_projection_angles(angles: ProjectionAngles)

property shared_array: SharedArray

sino(slice_idx) → ndarray

sino_as_image_stack(index) → ImageStack

A single sinogram slice as an ImageStack in projection ordering

property sinograms

slice_as_array(index) → ndarray

slice_as_image_stack(index: int) → ImageStack

A slice, either projection or sinogram depending on current ordering

property uses_shared_memory: bool

property width
