Schematic description of Brain Positioning System principle. A 3D Doppler Volume acquired at the beginning of the imaging session is automatically registered online to the 3D Doppler Reference (A) which was pre-aligned offline with a modality of interest, here the Allen Mouse Brain Common Coordinates Framework Atlas (B), but could be any other modality providing structural or functional information (D). As a result, the anatomic information provided by the modality can be propagated to the fUS experimental framework and used for automatic delineation of the vascular landmarks and atlas-based positioning (D).
