TomoPhantom [1] is a toolbox to generate customisable 2D-4D phantoms (with a temporal capability) and their analytical tomographic projection data (parallel-beam geometry). It can be used for testing various tomographic reconstruction methods, as well as image processing methods, such as, denoising, deblurring, segmentation, and machine/deep learning tasks. |
TomoPhantom is recommended for various image processing tasks that require extensive numerical testing: image reconstruction, denoising, deblurring, etc. In particular, TomoPhantom is best-suited for testing various tomographic image reconstruction (TIR) methods. For TIR algorithms testing, the popular Shepp-Logan phantom is not always a good choice due to its piecewise-constant nature. This toolbox provides a simple modular approach to efficiently build customisable 2D-4D phantoms consisting of piecewise-constant, piecewise-smooth, and smooth analytical objects as well as their analytical Radon transforms .
- Generate 2D and 3D synthetic phantoms made of Gaussians, parabolas, ellipses, cones and rectangulars.
- Generate simple temporal extensions of 2D and 3D phantoms.
- Calculate analytical Radon transforms of 2D-4D models and also their numerical projections.
- Model a variety of tomographic data artefacts (noise models, zingers, rings, shifts, partial volume effect and others).
Tomophantom is distributed as a Python conda package for Linux/Windows/Mac OS's:
conda install -c httomo tomophantom
