spectrIm-QMRS
Version 3.0.1 Alpha
Recommended release
Version 3.0.1 alpha, released on 20.07.2026, is distributed as a self-contained ZIP package. The required Java and Python runtime components are included, so users do not need to install these separately on hospital or research workstations.
Download spectrIm-QMRS-v3.0.1-alpha-W11-x64-distributable.zip,
extract it to a suitable local folder, and start the
application with start_spectrIm.bat from the
extracted release directory.
Release date: 20.07.2026
The release ZIP is large. Please allow a few minutes for the download and first start, especially from slower hospital or institutional network connections.
The package contains the complete spectrIm-QMRS v3.0.1 alpha distribution, including the Java runtime and the Python runtime needed by the HLSVD processing workflow. The bundled Python 3.12 environment already contains NumPy and SciPy versions compatible with the compiled HLSVD code used by spectrIm-QMRS.
Users should not replace the bundled Python packages with newer NumPy or SciPy releases unless they are deliberately testing a developer build. Newer numerical-library versions may not run the compiled HLSVD component correctly.
After extracting the ZIP file, run start_spectrIm.bat.
The launcher changes to the extracted release folder, verifies that
the bundled Java executable and spectrIm-QMRS.jar are
present, and then starts the application with the bundled Java runtime.

On first use, spectrIm-QMRS prepares its clinical working directory,
.SpectrImClinicalQMRS. This directory can contain MRS(I)
patient data, TDFDFit models, ILV basis-simulation models, generated
output, reports, and other working files. Choose a storage location
that can handle large future datasets and that satisfies your local
data-protection rules.
Users who previously worked with a spectrIm-QMRS v2.x release
should remove or rename the old .SpectrImClinicalBoot
directory in their home directory before using v3. The v2 and v3
bootstrap layouts should not be used in parallel.
Renaming is the safer choice when old models, settings, or example
data may still be needed. For example, rename
.SpectrImClinicalBoot to
.SpectrImClinicalBoot_v2_backup before starting the
v3 alpha release.
Older installation-based spectrIm-QMRS releases remain available for reproducibility, legacy comparisons, and established v2 workflows. They are intentionally separated from the recommended v3 alpha download so new users do not accidentally start with an outdated package.
The previous website is preserved as a historical reference: Open archived v2.x website.
Two anonymized spectroscopy example datasets are available for testing and teaching: a Siemens proprietary spectroscopy DICOM archive and a Philips enhanced spectroscopy DICOM archive.
An anonymized Siemens spectroscopy DICOM archive from an IDH-mutant glioma case for testing MRS(I) loading, spectroscopy grid display, and the v3 Clinical Viewer workflow.
Siemens-Spectro-Dicom-Proprietary.zip, approx. 106.6 MB.
An anonymized Philips enhanced spectroscopy DICOM archive from a post-mortem case for testing enhanced DICOM spectroscopy loading and clinical browser workflows in spectrIm-QMRS.
Philips-Spectro-Dicom-Enhanced.zip, approx. 233.8 MB.
Extract the archives locally and mount the extracted folder in spectrIm-QMRS. More context is available on the example dataset page.
