CTSimU Scenario Descriptions 1.2

This is the specification for a JSON-based file format to handle the parameters of a full industrial CT scan scenario, intended for describing virtual CT scenarios for simulations, as well as for documenting real CT scan geometries and acquisition parameters and their measurement uncertainties.

Specification version 1.2, released under the Apache 2.0 license.

A PDF document of this specification is available.

Example scenarios and simulated projection images can be found on the specification’s Github repository.
