An Arteriography is available for every participant. In time-of-flight angiography, flowing blood, such as the one in arteries, appears much brighter than stationary brain tissue. The provided images have partial brain coverage — approximately the same volume as the functional MRI scans for the audio movie. The complete description of this acquisition has been published in:
Hanke et al. (2014). A high-resolution 7-Tesla fMRI dataset from complex natural stimulation with an audio movie. Scientific Data, 1.
The sample image below is a low-resolution demo of the actual angiographies in the dataset. For more information on this image type, see Wikipedia.
