The transcranial Doppler echo data was recorded from both healthy and neurocritical care patients. The insonated cerebral vessels were the middle cerebral artery (MCA) and the internal carotid artery (ICA). The ultrasound device used in this study was the Philips CX50.
More detailed instructions and code will be provided once the review process of our paper "Adaptive Maximal Blood Flow Velocity Estimation from Transcranial Doppler Echos" is concluded.
Methods: The transcranial Doppler (TCD) data were collected from healthy volunteers at Massachusetts Institute of Technology (MIT) and from patients in neurocritical care at Boston Medical Center (BMC). Data collection occurred between 2016 and 2020, was approved by the MIT and BMC Institutional Review Boards, and informed consent was obtained from the subjects directly at MIT or from the patients or their legally authorized representatives at BMC. The data consists of 16 recordings from 6 healthy subjects and 29 recordings from 12 neurocritical care patients.
How-to: Use the 'spectrogram_viewer.m' MATLAB script to visualize the Doppler spectrograms. In this script, set the variables 'filepath' and 'filename' to point to the TCD data.
