US Patent 9192322 Mapping vascular perfusion territories using magnetic resonance imaging

Techniques, systems computer program products are disclosed for mapping of vascular perfusion territories by applying a train of pseudo-continuous radio frequency tagging pulses to modulate a first magnetization of one or more blood vessels that supply blood to one or more vascular perfusion territories, applying an encoding scheme using unipolar transverse gradient pulses to modulate a second magnetization of blood vessels of the vascular perfusion territories, obtaining efficiency for each blood vessel based on the applied encoding scheme and separating the vascular perfusion territories by using the obtained tagging efficiency in a decoding process.
