Abstract
A specific absorption rate (SAR) value acquisition method in magnetic resonance imaging includes acquiring a mapping relation between distribution data of radio frequency (RF) coil transmission field of each channel of an RF transmitter coil and distribution data of RF electric field of each channel of the RF transmitter coil, obtaining a mapping relation set, acquiring first distribution data of RF coil transmission field of each channel during an examination of a test person, determining first distribution data of RF electric field of each channel during the examination of the test person according to the first distribution data of RF coil transmission field of each channel and the mapping relation set, adjusting a weight of each channel according to the first distribution data of RF electric field of each channel acquired during the examination of the test person, and determining a distribution of SAR values of the test person.
