Welcome to Sdr2

Simple Dicom Reader 2 (Sdr2) is yet another DICOM to NIfTI converter. Sdr2 is NOT APPROVED FOR CLINICAL USE and it is in beta phase.

Sdr2 utilizes a large amount of code from other projects, which are published under different terms of license. Please refere to the 'About' page.
Sdr2 itself is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 2 of the License, or (at your option) any later version.


Volumetric medical imaging aims at combining information from different image sources and modalities into one analytical framework. Usualy the first and crucial step in this process is to convert a set of DICOM slice images into one properly oriented and scaled voxel volume. Some data formats have been developed to store and and analyze these medical voxel volumes. Two of them, Mayo Analyze 7.5 and its successor NIfTI, are widely used. Conversion of DICOM data to NIfTI format is implemented in couple of open source projects (notably ITK-SNAP, 3DSlicer, and other tools).
At our side we were in trouble with some mixed MRI series, where two sequences are combined in one series number. The raison d'etre for Sdr2 was to resolve this issue.

Sdr2 was developed as a helper tool for Ogles2 and other applications which make use of NIfTI-1 image data format.
