Calgary-Campinas Public Brain MR Dataset

General Information

A collaborative effort between researchers at the Vascular Imaging Lab located at the University of Calgary and the Medical Image Computing Lab located at the University of Campinas (UNICAMP) originated the Calgary Campinas public brain magnetic resonance (MR) images dataset. The dataset was first released with the following publication:

  • We added new data to our initiative! We have created a hypothalamus segmentation benchmark and a thalamus benchmark. The data is initially available through the GDrive and OneDrive links, but we hope to add it to the CONP portal very soon.

  • The MC-MRRec challenge has received a new submission and Track 02 of the challenge has a new leader!

Big Data

The goal of this dataset is that the scientific community use it to develop innovative and fast big data (i.e. deep learning) models to reconstruct, process and analyse brain magnetic resonance (MR) images. The key for developing big data applications is to have good data and representative of the variability we encounter in real applications. In the initial Calgary-Campinas (CC) dataset release we provided T1 volumes acquired in 359 subjects on scanners from three different vendors (GE, Philips, and Siemens) and at two magnetic field strengths (1.5 T and 3 T). The scans correspond to older adult subjects. The second dataset release included raw MR data.

Data Integration

Medical imaging data is continually revisited to guide decisions around future episodes of care. That is currently not the standard for image acquisition and reconstruction. We need better data integration strategies to optimize image acquisition and reconstruction. We are working on that. We hypothesize that we can leverage past subject-specific imaging information to enhance the reconstruction of following imaging exams (see figure below). We start our investigation with MR, but there is no reason that this paradigm cannot be applied across modalities. The raw MR data we currently provide corresponds to a single snapshot in time of a subject's brain. Our first edition of our online MR reconstruction challenge focus on reconstructing that brain snapshot from undersampled data with high fidelity compared to the fully sampled reconstruction. We are acquiring longitudinal data that we expect to make publicly available shortly. In the second edition of the challenge, we want to see if our hypothesis is confirmed (i.e. leverage longitudinal information to enhance reconstruction).
