1. An apparatus for generating a magnetic resonance image, the apparatus comprising:
- a coil for receiving a plurality of magnetic resonance signals generated by applying an electromagnetic wave signal having a plurality of pulses corresponding to multi-type atomic nuclei to a target object,wherein the coil receives a second magnetic resonance signal generated by applying at least one second pulse having a frequency corresponding to a second type of atomic nucleus to the target object between a time when at least one first pulse having a frequency corresponding to a first type of atomic nucleus is generated and a time when a first magnetic resonance signal generated by applying the at least one first pulse to the target object is received; and
an image generating unit for generating the magnetic resonance image from the magnetic resonance signals,wherein the image generating unit obtains first k space data corresponding to the first magnetic resonance signal and second k space data corresponding to the second magnetic resonance signal in which sampled signals are less than sampled signals in the first k space data.

Abstract
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.
