Abstract
An NMR system includes a transceiver which receives NMR signals of varying amplitude during a scan. The gain of the receiver is dynamically changed during the scan to provide an optimal SNR figure without overranging the transceiver's A/D converter. The acquired NMR signals are normalized prior to image reconstruction using correction factors for gain and phase stored in a normalization table.
