| Abstract: | Magnetic resonance imaging (MRI) pursues high signal-to-noise ratio (SNR) and fast acquisition. Compared with single channel radiofrequency (RF) coil, multi-channel RF coils have the features of high SNR, high resolution and parallel imaging. One software for performance evaluation based onk-space data from multi-channel coils was developed, which serves to help the design and production of RF coils. Speciifcally, it facilitates to calculate the noise covariance matrix, SNR and geometry factor of multi-channel coils more precisely by using this software. |
