Abstract

The high-frequency coil assembly of the present invention includes a first high-frequency coil, a second high-frequency coil, and a third high-frequency coil. The first high-frequency coil receives first magnetic resonance signals from the subject. The second high-frequency coil receives at least one of the first magnetic resonance signal and the second magnetic resonance signal from the subject. The third high-frequency coil receives at least one of the first magnetic resonance signal, the second magnetic resonance signal, and the third magnetic resonance signal from the subject. In addition, the third high-frequency coil has a different shape from at least one of the first high-frequency coil and the second high-frequency coil, so that the local sensitivity of the imaging region can be improved.

Description

technical field

[0001] The present invention relates to a high-frequency coil assembly for collecting magnetic resonance signals based on magnetic resonance phenomena from a subject, and a magnetic resonance imaging apparatus having the high-frequency coil assembly. Background technique

[0002] Magnetic resonance imaging performed by a magnetic resonance (MRI) imaging device is a high-frequency signal of its Larmor frequency that is used to magnetically excite the nuclear spins of the subject placed in a static magnetic field. Magnetic resonance (MR) signal reconstruction imaging method.

[0003] To implement this imaging method, the magnetic resonance imaging apparatus has a static magnetic field magnet that generates a static magnetic field, and a mechanism that applies gradient magnetic field pulses and high-frequency magnetic field pulses to the subject in a predetermined pulse sequence. Wherein, the gradient magnetic field pulse is sent to the subject through the grad...
