Simple medical imaging visualization tool designed for NIfTI images. Includes dcm2nii for conversion of DICOM, Philips, and other proprietary formats.
MRIcron is a viewer for brain imaging data.
You can download the software from several locations:
curl -fLO https://github.com/neurolabusc/MRIcron/releases/latest/download/MRIcron_linux.zip
curl -fLO https://github.com/neurolabusc/MRIcron/releases/download/MRIcron_macOS.dmg
curl -fLO https://github.com/neurolabusc/MRIcron/releases/latest/download/MRIcron_windows.zip
Once you have downloaded and extracted the software, you may want to visit the wiki for usage advice.
This software includes a BSD license
MRIcron is robust and stable, but development efforts have moved to MRIcroGL. The primary disadvantage of MRIcroGL is that it requires support hardware accelerated OpenGL 3.3 graphics. Therefore, MRIcron remains useful for users of older computers or when connecting to remote supercomputer clusters. These users may also consider fsleyes which can be set up to only require OpenGL 1.4 and indirect rendering.
The latest releases of MRIcron only include the MRIcron viewer and the dcm2niix image converter. Once upon a time, the software was distributed with statistics (NPM) and legacy image converter (dcm2nii). One can still download old releases of MRIcron from NITRC or compile these legacy tools (see next section).
NPM is a tool for non parametric analysis of neuroimaging lesion data. dcm2nii is designed for converting the complicated DICOM format used in medical imaging to the simple NIfTI format preferred by scientists. These tools are mature and hopefully robust but no longer in active development.
You can build MRIcron using Lazarus.
