ABSTRACT:
An MRI system acquires NMR signals and digitizes them at a fixed sample rate. A lower, prescribed sample rate is obtained by transforming the acquired NMR signal using a weighting function calculated from scan parameters. The transformation includes multiplying by the weighting function and convolving the NMR signal with the complex conjugate of the weighting function.
