Figure 4From: Comprehensive 4D velocity mapping of the heart and great vessels by cardiovascular magnetic resonance 3D pathlines in a normal thoracic aorta illustrating the temporal evolution of blood flow at five different instants in systole. Pathlines were repetitively emitted at successive instants and originate from two emitter planes, one in the ascending aorta and one in the proximal descending aorta. Color coding reflects the local absolute velocity. See also additional file 2.Back to article page
