Title:
WIRELESS TRANSMISSION METHOD FOR SIGNAL OF NUCLEAR MAGNETIC RESONANCE IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/033029
Kind Code:
A1
Abstract:
Provided is a wireless transmission method for a signal of a nuclear magnetic resonance imaging device. The method comprises: a local coil unit receiving an MR analog signal; after sequentially passing through a first frequency mixer, an analog-to-digital converter and a digital down converter, obtaining an MR digital baseband signal; performing interleaving, rate matching and channel coding on the MR digital baseband signal, so as to map the MR digital baseband signal to a wireless channel; after performing OFDM modulation on the digital signal, sending the digital signal to a wireless air interface; a receiver receiving the signal from the wireless air interface, and performing OFDM demodulation; performing channel decoding, de-rate matching and de-interleaving, so as to restore the MR digital baseband signal; and after the MR digital baseband signal sequentially passes through a digital up-converter, a digital-to-analog conversion module and a second frequency mixer, obtaining the MR analog signal. By means of the method provided in the present invention, the power consumption and costs can be reduced, a better image quality and a higher signal-to-noise ratio can be obtained, the spectrum utilization rate and reliability of wireless transmission of a nuclear magnetic resonance signal are ensured, and a system can also be more concise due to the wireless transmission of the signal.
