NDT X-ray Toolbox is a free Android app developed by VisiConsult X-ray Systems Solutions GmbH under the Business and Productivity category. It is a useful tool that simplifies everyday x-ray calculations. The app contains a variety of features that include Geometric Calculations, X-ray Standards, Image Quality Control, and CT Calculations. All the formulas and shortcuts are given and explained in the app, which makes it easy to use even for those who are not familiar with the calculations.

One of the main features of the NDT X-ray Toolbox is the ability to choose the detector you have, which eliminates the need to manually write the pixel pitch. The app also has a modern design that makes it fun to use. Additionally, the developers are working on adding more features to the app, so it will be updated soon.
