ABSTRACT:
An MRI system performs a scan to acquire NMR signals from which an image can be reconstructed. The NMR signals are compressed prior to digitization by a nonlinear preamplifier, and after digitization, the signal is restored to the correct amplitude by a decompression process. The SNR of the reconstructed image is improved without increasing the size of the analog to digital converter.
