    摘要： An electromagnetic wave signal, having a pulse train in which pulses having a plurality of frequencies corresponding to multi-type atomic nuclei are arranged in a line, is applied to a target object located in a magnetic field by using a radio frequency (RF) coil in the magnetic field. Data of magnetic resonance signals corresponding to the multi-type atomic nuclei is collected from the RF coil, and multi-type magnetic resonance images corresponding to the multi-type atomic nuclei are generated by using the data of the magnetic resonance signals.
