Abstract
Methods, systems, and computer-readable storage mediums for correcting time in a nuclear magnetic resonance device are provided. In one aspect, a method includes obtaining respective transmission time delays of three gradient pulse signals that are generated by a three-dimensional gradient subsystem of the nuclear magnetic resonance device and include a slice-selection gradient signal, a phase-encoding gradient signal, and a frequency-encoding gradient signal, determining a time correction value according to the obtained respective transmission time delays of the three gradient pulse signals, and correcting a respective output time of each of the three gradient pulse signals, an output time of a radio-frequency (RF) pulse signal generated by a RF transmitting subsystem of the nuclear magnetic resonance device, and a reception time of a magnetic resonance signal received by a RF receiving subsystem in a scanning cycle according to the determined time correction value.
