Sideband processing for magnetic resonance
A method includes applying a pulse train to a spin system in a scanner. The pulse train has a plurality of discontinuities in a time domain. The method includes receiving a response from the spin system. The response corresponds to a gated signal. The method includes accessing a correction factor corresponding to the scanner. The method includes calculating a correction to the response based on the correction factor. The method includes generating an output based on the correction.
1. A method comprising:
applying a pulse train to a spin system in a scanner, the pulse train having a plurality of discontinuities in a time domain;
receiving a plurality of responses from the spin system, each response of the plurality of responses including baseband content and sideband content;
generating a correction factor based on the baseband content and the sideband content, wherein generating the correction factor includes processing a first response of the plurality of responses and processing a second response of the plurality of responses wherein a gate position of a transmitter and a receiver for the first response is time shifted relative to the gate position of the transmitter and receiver for the second response;
calculating a correction based on the correction factor; and
generating an image based on the correction.
2. The method of claim 1 wherein generating the correction factor includes processing oversampled data corresponding to the plurality of responses.
3. The method of claim 1 wherein generating the correction factor includes calculating an interpolation operator corresponding to the plurality of responses.
4. The method of claim 1 wherein generating the correction factor includes generating an interpolation operator.
