PhysioNet is seeking contributions of data sets that can be made freely available in PhysioBank. We welcome contributions of digitized and anonymized (deidentified) physiologic signals and time series of all types. If you have a data set that may be suitable, please review PhysioNet's guidelines for contributors and then contact us.
From time to time, we receive requests for physiologic data of types that are not well represented in PhysioBank, and we have often been able to locate suitable data sets. Among the data sets sought are:
- ECGs with raw E-A-S-I signals
The EASI lead configuration was described in:
Dower GE, Yakush A, Nazzal SB, Jutzy RV, Ruiz CE. Deriving the 12-lead electrocardiogram from four (EASI) electrodes. J Electrocardiol. 1988;21 Suppl:S182-7.We are seeking untransformed recordings made using this lead configuration.
- EEGs from patients with tinnitus
- For a study on detection of tinnitus, a student seeks EEG recordings from individuals with tinnitus and from healthy controls.
- Electromyograms (EMG)
- See this announcement for details, and for information about annual awards for the most significant contributions.
- EMGs of wrist movements
- To support work on EMG-based control of prosthetic hands, a student seeks surface EMG signals of wrist movements, including wrist extension, wrist flexion, hand open, and hand close.
- Functional near infrared signals (fNIRs) from the brain
- Seeking fNIRs recorded from the prefrontal cortex of the brain in different mental workload levels, using a 16-channel continuous wave (CW) fNIRs system.
- Joint kinematic data in gait
- Pediatric ECG and other signals
- Limited examples are included in a few PhysioBank databases.
- Phonocardiographic signals
- Uncompressed recordings preferred.
- Signals associated with images
- Suitable data sets might include data from cell culture experiments and other in vitro studies in which image data complement or provide support for interpretation of signals, as well as in vivo data such as the PhysioNet/Computers in Cardiology 2007 data set (which included cardiac MR images and body surface potential maps).
