Multicenter Single Subject Human MRI Phantom Dataset

Overview

This dataset consists of brain scans of a single human phantom acquired on multiple MRI devices across North America over a period of 11 years. In addition to the human brain images, lego phantom scans have been acquired in parallel for quality assessments over time across sites.

MRI modalities include: T1-weighted (t1w), T2-weighted (t2w), resting state BOLD (bold), 25-direction DWI (dwi25), 65-direction DWI (dwi65) as well as fieldmaps for the BOLD and DWI acquisitions (fieldmapBOLD and fieldmapDWI).

The human phantom data were collected once a year during two MRI sessions. Those two sessions were either performed the same day or with a few days apart.

Data organization and file format

Data are organized by subject_ID/Visit_Label.

The ID of the human phantom subject is 963271 and the 9 other subjects present in the dataset are lego phantoms.

Visit labels for the human phantom acquisitions are labelled according to the convention <SiteAbbreviation>_<ScanSessionNumber>_<AcquisitionDate> Example: MNI_SCAN1_20101125 corresponds to scan session number 1 at the MNI site performed on November 25th, 2010.

The visit labels of the lego phantom acquisitions are labelled according to the convention <SiteAbbreviation>_<AcquisitionDate>

All images are available in MINC format.

Information about the scanning sites

All MRI scanners were manufacured by SIEMENS.
