phantom3D

This project content files for constructing a 3D phantom used in MRI or CT scanners to test, train and validate image acquisitions during development of acquisition sequences or experimental protocols. The phantom is constructed with 3 parts than can be easily printind on 3D printers. 3D items are designed with the free software Blender and the exported templates for printing are given in the STL format. The phantom is designed to obtain anatomical views in neurological conventions, from the left (L) to right (R) axis, the inferior (I) to superior (S) axis, and the posterior (P) to anterior (A) axis. This coordinate system is used in neuroimaging, for example when working with the NIfTI and BIDS. The project is structured as follows: /distrib: old and versioned files. /src: contents current and associated files /fig: contents some figures. /derivatives: contents code to: Create templates for MRI and CT scans in RAS coordinate systems (NIfTI); Detect the orientation of the phantom in 3D recordings; Fix the affine transformation for incorrectly oriented NIfTI files.
