Problems solved by technology
However, it is difficult to properly control wireless coils since LOS communication cannot be guaranteed between corresponding antennas
[0007] Therefore, these communication characteristics are often difficult to establish and / or maintain in the MR environment due to many reasons such as system noise, interference, movement and physical limitations of wireless type RF
For example, channel capacity is limited by bandwidth and signal-to-noise ratio (SNR), assuming that the signal encoding method can tolerate a bit error rate (BER) up to a certain maximum value
For these reasons and others, it is difficult to establish a wireless communication channel with the desired throughput in an MR environment

A magnetic resonance (MR) system comprising: at least one radio frequency (RF) coil including an antenna for receiving induced MR signals and an antenna array including a transmit antenna and a receive antenna; a base transmitter system (BTS) of an antenna array configured to communicate with said RF coil using a selected space diversity (SD) method; and at least one controller for controlling said BTS and said RF coils to determine the number of transmit and receive antennas available, couple the transmit and receive antennas to form corresponding antenna pairs, and determine signal characteristic information (SCI) for the antenna pairs, and based on the determined The number of antennas and the determined SCI are used to select an SD transmission method for communication between the BTS and the RF coil, and an SD transmission method is established between the BTS and the RF coil according to the selected SD transmission method communication channel.
Description
technical field [0001] The present system relates to magnetic resonance (MR) systems employing high-throughput wireless communications for communication between coils and MR systems including a system controller, and more particularly to radio frequency (RF) coils for communication between coils and coils including MRI A high throughput wireless communication system for MR imaging (MRI) and MR spectroscopy (MRS) systems for transferring data between systems of a system controller of the system, and a method of operating the same. Background technique [0002] MRI is an imaging technique that uses frequency and phase encoding of protons for image reconstruction. More recently, wireless MRI radio frequency (RF) coils have become available and rely on wireless communication to transmit acquired information (eg, image information) to a system controller for further processing, presentation, and / or storage. [0003] More specifically, wireless RF coils may include multiple trans...
