It mainly has the ability to provide hemodynamics information, which is called noninvasive angiography clinically. It’s shown as follows:

·It can visually display the distribution and direction of blood stream so as to distinguish the arteries and veins clearly.

·It can help to understand the time phase and velocity of blood stream.

·It can help to find out splitting flow and back-streaming reliably.

·It can conduct quantitative analysis to the origin, width, length and area of blood stream.
