MC Dataset

MC Dataset is an extensive collection of datasets computed with PyXOpto Monte Carlo light propagation models. The readily available datasets are computed for a vast variety of sources, detectors and sample optical properties and include information of reflectance, transmittance, sampling volume and fluence/energy deposition data. The datasets can be easily customized through the dataset module of the PyXOpto project.

Links to the data files of the latest release

Datasets are split into multiple files to reduce the download size and to allow partial downloads. The following table has the links to the dataset files of the latest release. A more detailed description of the individual datasets is given in the following section.

Datasets

The following sections provide information on the four groups of datasets:

• MCML comparison datasets
• Layered media datasets (MCML)
• Voxelized media datasets (MCVOX)
• Sampling volume datasets (SV)

At the end of each section there is a breakdown of the directory tree and naming conventions that are used to organize the dataset files.

MCML comparison datasets

This dataset is intended for comparison with the MCML package. Datasets are computed for a 1-layer (1 mm and 100 mm thick) and 2-layer sample (0.1 mm and 1.0 mm thick layers). The optical properties are varied in the top sample layer:

• Absorption coefficient is sampled from [0.0, 2.5, 5.0] cm ^-1.
• Reduced scattering coefficient is sampled from [5.0, 20.0, 35.0] cm ^-1.
• Scattering phase function anisotropy is sampled from [0.1, 0.5, 0.9].
• The refractive index of the sample is set to:
  • 1-layer sample: 1.337,
  • 2-layer sample: 1.462 for the top layer and 1.337 for the bottom layer.
• The refractive index of the surrounding medium is set to 1.0.
• The remaining optical properties of the 2^nd layer are fixed to µ_a=0.5 cm^-1, µ_s'=20.0 cm^-1 and g=0.8.

The datasets are computed with a normally incident infinitely thin source. The reflectance and transmittance are collected through radial detectors with 500 concentric accumulators from 0 to 5 mm.
