METHOD FOR DETECTING BLOOD FLOW DIRECTION THROUGH SIGNAL INTENSITY GRADIENT VECTOR ANALYSIS IN ARTERIAL WALLS IN TIME OF FLIGHT MAGNETIC RESONANCE ANGIOGRAPHY, AND MEDICAL IMAGING SYSTEM USING SAME

摘要

Provided are a method for detecting a blood flow direction through a signal intensity gradient (SIG) vector analysis in arterial walls in time of flight magnetic resonance angiography (TOF MRA), and a medical imaging system using the same. According to an embodiment of the present invention, the method for detecting a blood flow direction comprises the following steps: detecting blood vessels from planar images of blood vessels; calculating an SIG vector in arterial walls of the blood vessels; and deriving a blood flow direction in the arterial walls. Accordingly, the method for detecting a blood flow direction may derive a blood flow direction by using only the TOF MRA images without additional image capturing, and provide information on the same.;COPYRIGHT KIPO 2016
