Abstract
A method for correcting a magnetic resonance imaging error using a heart rate interval may include: measuring T1 of a stand-alone phantom for correcting the error; obtaining a T1 map generated by mapping a recovery time according to a reference recovery rate of protons in heart tissues of a subject inverted by a radio frequency (RF) pulse in pixel units into a two-dimensional space; calculating a correction function based on the measured T1 of the phantom; and correcting an error of the T1 map based on the calculated correction function.
