MetPyX is a collection of tools for x-ray metrology. X-ray metrology laboratories need to deal daily with a wide set of x-ray radiation qualities, the filtration thicknesses to get each one of those qualities, and the operational magnitudes for radiation protection. MetPyX provide tools to ease the management all of them. It is an open source, GPLv3-licensed library for the Python programming language. It is compatible with Python 3.
MetPyX provides two features:
- Manage x-ray radiation qualities and their corresponding filtration thicknesses. With MetPyX you can: get the x-ray radiation quality series or the radiation qualities of a specific series, check if a series/quality is an x-ray radiation series/quality, get the radiation qualities of a radiation quality series, and get the series, peak kilovoltage or filtration thicknesses from a specific radiation quality.
- Manage x-ray operational quantities for radiation protection and their corresponding irradiation angles. With MetPyX you can get the operational quantities for x-rays, check if a quantity is an operational quantity for x-rays, and get the irradiation angles for an operational quantity.
MetPyX can be installed from the Python Package Index (PyPI) by running the following command from a terminal:
pip install metpyxThe tool that MetPyX provides to manage x-ray radiation qualities is the XrayQualities class. With XrayQualities class you can:
- List the X-ray radiation quality series or the radiation qualities of a specific series.
- Check if a series/quality is an x-ray radiation series/quality.
- Retrieve the radiation qualities of a radiation quality series.
- Retrieve the series, peak kilovoltage or filtration thicknesses for a specific radiation quality.
The next script show how to use all the tools provided by the XrayQualities class.
