## What is NDT X?

NDT X-ray Toolbox is a useful app for x-ray calculations everyday needed.
NDT X-ray Toolbox contains: 
- An image viewer for TIFF and DICONDE x-ray images
- Geometric Calculations (Calculation of M, M opt, Ug, Ut)
- X-ray Standards (API 5L, ISO 10893-7, ISO 17636-2 including SNRn Calculation)
- Image Quality Control (ISO 19232-1 / EN 462-1, ISO 19232-2)
- CT Calculations (Calculation of effective Pixel Size, Number of Pictures, Reconstructed Data Size, Best voxel resolution, Tube Voltage)
- all Formulas and Shortcuts are given and explained so that if you don't know what a particular Formula/Shortcut means, you can have a quick look in our app, too.
We are working on additional features, so it will be updated soon.
Also some nice tools are included, e.g. that you can choose, which Detector (the most common Detectors are included) you have, so that you do not have to check out and manually write the Pixel Pitch if you know which Detector you have.

Besides NDT X-ray Toolbox is convincing with a modern design that let it make fun to use it.
