Methods, devices, and systems for data monitoring are provided. In one aspect, a method of data monitoring, applicable to a magnetic resonance system, includes: obtaining radio frequency (RF) waveform information which is to be sent to an RF transmitting coil of the magnetic resonance system; extracting target waveform information within a current sliding window from the RF waveform information, with a current time point being located within the current sliding window; obtaining, based on the target waveform information, target magnetic flux densities corresponding to the current sliding window; and determining a current real-time specific absorption rate (SAR) based on the target magnetic flux densities.

Methods, apparatuses and devices for monitoring data and magnetic resonance systems

Methods, devices, and apparatus for signal reception are provided. In one aspect, a receiver includes: a group delay circuit configured to perform a group delay on an original analog signal to obtain a group delayed analog signal, a controller configured to determine a gain mode according to an amplitude of the original analog signal, a gain circuit coupled to the group delay circuit and the controller and configured to adjust a power of the group delayed analog signal according to the determined gain mode to obtain an adjusted analog signal, an analog-to-digital converter coupled to the gain circuit and configured to perform an analog-to-digital conversion on the adjusted analog signal to generate a digital signal, and an amplitude-phase-processing circuit configured to adjust amplitude and phase of the digital signal according to the determined gain mode.
