Resolution, pixel size, and sampling

A tutorial to explain resolution in imaging

The relation between pixel size, sampling, and resolution

• What is the pixel size made up of?
• What is resolution

How to measure the pixel size

• Devices to measure the pixel size
• Method to measure the pixel size
  • Manually
  • Automated
    • the geometry math
    • Image analysis

How to measure the resolution (under development)

• Test patterns, line pairs, Siemens star, line patterns
• Edge response
  • FWHM - fit Voigt function (approximate vs exact) https://scipython.com/book/chapter-8-scipy/examples/the-voigt-profile/
  • MTF - levels and what they mean

Misc

Could be added

• Quantum efficiency
• Edge spread from different scintillator materials
• Resolution and noise
