METHOD FOR MEASURING PULSATILE VELOCITY FROM PHASE CONTRAST MAGNETIC RESONANCE IMAGES AND SYSTEM USING THE SAME

摘要

A method for measuring blood flow velocity from a phase contrast MRI image and a system using the same are provided. A method for measuring blood flow velocity from a phase contrast MRI image according to an embodiment of the present invention includes acquiring a single reference image which is a first image of one cardiac cycle and is an image immediately after an electrocardiogram R-wave, Obtaining a first rate encoded image and a second rate encoded image which are temporally continuous images after the image, generating a first rate image based on the reference image and the first rate encoded image, Generating an acceleration image based on the second rate encoded image, generating a second velocity image based on the first velocity image and the acceleration image, and generating a second velocity image based on at least the first velocity image and the second velocity image, And a step of measuring the temperature. According to the present invention, it is possible to measure a blood flow velocity with a higher velocity-to-noise ratio and a temporal resolution in a phase-contrast MRI imaging technique.
