Magnetic resonance imaging system using radio frequency (RF) coils corresponding to volumes representing target regions

Provided are apparatuses and methods for magnetic resonance imaging (MRI). The magnetic resonance imaging (MRI) method includes applying radio frequency (RF) pulses to an object in a magnetic field, the RF pulses having different frequency bands for each of at least two types of nucleus in the object; applying predetermined pulse sequences for each type of nucleus to the object; receiving magnetic resonance signals emitted by each nucleus in response to the RF pulses and the predetermined pulse sequences; and generating an image of the object based on the received magnetic resonance signals.

Magnetic resonance imaging (MRI) system and method

Provided is a magnetic resonance imaging and positron emission tomography (MRI-PET) system. The MRI-PET system includes a PET unit and a radiofrequency (RF) coil disposed within a gradient coil assembly.

Magnetic resonance imaging and positron emission tomography system

A method of shimming a magnetic field, includes applying radio frequency (RF) signals to an object, using a transceiver coil, and calibrating phase offsets of magnetic resonance signals acquired from the object through a receiver coil. The method further includes generating RF signals to be applied through the transceiver coil based on magnetic resonance signals acquired from the object through the transceiver coil and the calibrated magnetic resonance signals.
