A study of Wideband MR imaging: SNR and CNR
Most of the MR image accelerating methods suffer from degradation of acquired images, which is often correlated with the degree of acceleration. However, Wideband MRI is a novel technique that transcends such flaws. In this study we demonstrate that Wideband MRI is capable of obtaining images with identical quality as conventional MR images in terms of SNR, CNR (contrast-to-noise ratio) and ima...
متن کاملUnderstanding the impact of VCR operations in P2P VoD systems
One of the main challenges faced by peer-topeer (P2P) video-on-demand (VoD) systems is their ability, or lack thereof, to provide VCR functionality (e.g. random jump operations). Such jump operations can have special impact in the server load during flash crowd events, since the server is the only node in the system with a full copy of the video. Currently, there is little knowledge of the impa...
متن کاملA Nonlinear GRAPPA Method for Improving SNR
INTRODUCTION GRAPPA [1] reconstructs the missing k-space data by a linear combination of the acquired data using a set of weights obtained through calibrations. Several methods have been proposed in recent years to improve GRAPPA using localized coil calibration and variable density sampling [2], multicolumn multiline interpolation [3], regularization [4,5], reweighted least square [6], high-pa...
متن کاملOn Non-coherent MIMO Capacity in the Wideband Regime: Interplay of SNR, Antennas and Coherence
We consider a multiple-input, multiple-output (MIMO) wideband Rayleigh block fading channel, where the channel state is unknown to both the transmitter and the receiver. With only an average power constraint, we compute the capacity of this channel and consider it’s interaction with the coherence length, number of transmit and receive antennas and receive signal-to-noise ratio (SNR) per degree ...
متن کاملSNR Degradation in Undersampled Phase Measurement Systems
A wide range of measuring applications rely on phase estimation on sinusoidal signals. These systems, where the estimation is mainly implemented in the digital domain, can generally benefit from the use of undersampling to reduce the digitizer and subsequent digital processing requirements. This may be crucial when the application characteristics necessarily imply a simple and inexpensive senso...
