Horos/Osirix Plugins

DTIMap

This plugin calculates FA, Mean diffusivity (MD), largestest (D1), second (D2) and smallest (D3) eigen diffusivity, radial diffusivity (Rad) and color coded FA maps from DTI images.

Exporter

This plugin exports/imports 3D/4D images to/from nifti type to interface with software packages such as FSL, SPM. A typical use is to use the plugin to export DTI images to nifti format and perform eddy current correction using FSL, and import the images back.

NiftiToDICOM

This plugin imports image from nifti file to Osirix database.

R2* Mapping

A nonlinear approximate message passing (AMP) framework is proposed to recover R2* map and phase images from undersampled measurements.

Quantitative Susceptibility Mapping

We propose an approximate message passing (AMP) approach for QSM with built-in parameter estimation, and incorporate the nonlinear formulation of the dipole inversion to achieve a robust recovery of the susceptibility maps.
