Method of derivation for hemodynamics and MR-signal intensity gradient(or shear rate) using Time-Of-Flight - Magnetic Resonance Angiography

摘要

The flow characteristics and MR- signal intensity gradient induced by the TOF-MRA method is provided . Flow characteristic induction method according to an embodiment of the present invention , MRA obtains the blood vessel cross-sectional image , and detects the blood vessel boundary identify the blood vessel , the blood vessel pseudo- coloring to provide a blood flow image . As a result , an accurate blood flow characteristics, such as blood flow or blood flow dynamics through a relatively simple algorithm using the TOF-MRA induced by very fast and , by this analysis and to determine the flow characteristics , so it can be applied to the diagnosis and treatment of vascular disease is . ;
