1. A magnetic resonance scanning control method, comprising:
acquiring a three-dimensional body model of a scan subject;
estimating, on the basis of the three-dimensional body model, a value of a first body parameter and a value of a second body parameter of the scan subject;
determining a specific absorption rate on the basis of a site to be scanned of the scan subject, the value of the first body parameter and the value of the second body parameter;
determining an implant location in the three-dimensional body model;
determining a root mean square value of a radio frequency field on the basis of the implant location and the site to be scanned; and
adjusting a waveform of radio frequency transmission pulses based on the determined specific absorption rate and the root mean square value of the radio frequency field.
