Problems solved by technology

However, it is difficult to remove useless data because it is impossible to identify from which RF coil the collected data comes from on the control device side
[0011] Therefore, it is necessary to wirelessly transmit the signals received by all the RF coils to the control device, and extract only the data required for diagnosis after data processing, but this involves an increase in useless data processing

Abstract

The present invention provides a magnetic resonance imaging apparatus, a RF coil system and an imaging method of magnetic resonance. The magnetic resonance imaging apparatus (1) has at least one RF coil and data processor. One side of the RF coil generates inherent information, another side of the RF coil receives magnetic nuclear resonance signal, and the received magnetic nuclear resonance signal and the inherent information are sent by wireless.Data processor receives the magnetic nuclear resonance signal and the inherent information sent by wireless, and generates image data based on magnetic nuclear resonance signal according to inherent information.

Description

technical field [0001] The present invention relates to the magnetic excitation of the nuclear spins of the subject with a Larmor frequency (RF: radio frequency) signal, and according to the nuclear magnetic resonance (NMR: nuclear magnetic resonance) signal that occurs with this excitation. A magnetic resonance imaging (MRI: magnetic resonance imaging) device and an RF coil system for reconstructing an image, in particular, relate to a magnetic resonance imaging device, an RF coil system and a magnetic resonance imaging method for wirelessly transmitting received signals. Background technique [0002] Magnetic resonance imaging is an imaging method in which the nuclear spins of a subject placed in a static magnetic field are magnetically excited by a Larmor frequency RF signal, and an image is reconstructed based on the NMR signal that accompanies this excitation. [0003] In recent years, the number of RF coils for receiving NMR signals tends to increase in MRI apparatuses...
