Featured Resources

NIH 32000 CT Images (https://nihcc.box.com/v/DeepLesion)

The National Institutes of Health’s Clinical Center has made a large-scale dataset of CT images publicly available to help the scientific community improve detection accuracy of lesions. While most publicly available medical image datasets have less than a thousand lesions, this dataset, named DeepLesion, has over 32,000 annotated lesions identified on CT images. The descriptive publication can be found at https://doi.org/10.1117/1.JMI.5.3.036501.

National Sleep Research Resource (sleepdata.org)

The National Sleep Research Resource (NSRR) offers free web access to large collections of de-identified physiological signals and clinical data elements collected in well-characterized research cohorts and clinical trials. Users can query and search across thousands of data elements, identify those data of most relevance for given needs, explore the statistical distributions of each, and download the data. Physiologic signals from overnight sleep studies are available as downloadable EDF (European data format) polysomnograms (PSGs). Users can also download standard (Rechtschaffen and Kales or AASM) annotations of these PSGs, and summary measures derived from them. The first data set available includes over 8,000 studies from exams 1 and 2 from the Sleep Heart Health Study, with scheduled new data releases every quarter from additional data sets. NSRR also provides open-source software for viewing and analyzing these data.

CI2000 (www.bci2000.org)

BCI2000 is a general-purpose system for brain-computer interface (BCI) research. It can also be used for data acquisition, stimulus presentation, and brain monitoring applications. The mission of the BCI2000 project is to facilitate research and applications in these areas. The vision for the project is that BCI2000 will become a widely used software tool for diverse areas of real-time biosignal processing. BCI2000 supports a variety of data acquisition systems, brain signals, and study/feedback paradigms, data storage in BCI2000 native or GDF formats, and data import in Matlab and export into ASCII.

Development of BCI2000 is funded by NIH/NIBIB (R01-EB006356). The system is available for free for non-profit research and educational purposes at www.bci2000.org. To date, it has been acquired by about 400 laboratories around the world, and has been used in more than 120 peer-reviewed publications.

The Open-Source Electrophysiological Toolbox (oset.ir)

OSET is a collection of electrophysiological data and open source software for biosignal generation, modeling, processing, and filtering. The toolbox is distributed under the GNU General Public License and may be freely used or modified under the specified terms of use. The software has been developed mainly in Matlab and partially in C++, but translations to other languages are welcome.

OSET has contributed data to the PhysioNet/CinC Challenge 2013. Its contributors include researchers from Shiraz University (Shiraz, Iran), Sharif University of Technology (Tehran, Iran), the Institut Polytechnique de Grenoble (Grenoble, France), and the National Aerospace University (Kharkov, Ukraine).

Biomedical Technology Research Centers: Informatics Resources

PhysioNet was established in 1999 as one of nine Biomedical Technology Resources in Simulation and Computation supported by the NIH's former National Center for Research Resources (NCRR). In October 2008, NCRR changed the name of its Biomedical Technology Research Resources (grant mechanism P41) to Biomedical Technology Research Centers, and designated the former Resources in Simulation and Computation as Informatics Resources. The NCRR was dissolved at the end of 2011; most of the resources it had funded, including PhysioNet, were transferred over a period of several years to other institutes of the NIH. Those resources include:
