Example Neutron Datasets#
This page provides example neutron (and related) datasets for use with Mantid Imaging. These datasets are intended to help users quickly get started with visualization, corrections, and reconstruction workflows.
The datasets listed here are small, open-access, or synthetic where possible, and are suitable for tutorials, testing, and continuous integration (CI) workflows.
Overview#
The datasets included or referenced here are designed to:
Demonstrate visualization in Mantid Imaging
Show typical correction workflows (dark/flat correction, normalization, etc.)
Provide reproducible examples for tutorials and testing
Test Datasets Repository#
A small collection of test datasets is available via GitHub:
mantidproject/mantidimaging-data
This repository currently includes:
Neutron tomography of a flower
Acquired at IMAT at ISIS Neutron and Muon Source
Format: TIFF image stack
Use cases:
Basic visualization
Reconstruction workflows
Testing correction pipelines
X-ray tomography of a wire sample
Acquired at beamline i13 at Diamond Light Source
Format: NXTomo (NeXus) file
Use cases:
Testing NeXus file handling
Comparing neutron vs X-ray workflows
These datasets are intentionally small to allow fast download and use in CI environments.
Recommended Open Datasets#
A larger collection of open-access tomography datasets is available via Zenodo:
https://zenodo.org/collection/user-ccpi
Recommended neutron datasets include:
Lego Man Neutron Tomography Dataset
Format: TIFF projection images + metadata
Description:
A neutron tomography dataset of a Lego figure, acquired with both equidistant and golden angle sampling strategies.
Use cases:
Reconstruction algorithm comparison
Sampling strategy studies
Visualization examples
Aluminium Cylinder – Flexible Neutron Tomography Dataset
Format: TIFF projection images + metadata
Description:
A flexible neutron tomography dataset acquired with multiple exposure times and a highly composite number of projection angles.
Use cases:
Studying trade-offs between exposure time and number of projections
Optimizing acquisition strategies
Testing reconstruction robustness
Cone Beam CT Dataset
Format: TIFF projection images + metadata
Description:
X-ray cone-beam CT dataset of a walnut acquired at multiple dose levels. Includes TIFF projections and scan metadata describing scan geometry and parameters.
Use cases:
Testing cone-beam reconstruction workflows
Exploring dose vs image quality trade-offs
Practicing correction steps (dark/flat field)
Internal ISIS Example Datasets#
Additional datasets are available internally via the ISIS Data Analysis as a Service Ada system.
