1. A multichannel system comprising: an acquisition portion configured to acquire a multichannel signal including image data and signal noise; and a multichannel noise reduction module configured to obtain correlated noise between a plurality of channels within the multichannel signal, the correlated noise comprising correlation information associating noise between at least two channels; the multichannel noise reduction module configured to obtain at least one of a signal characteristic or uncorrelated noise from at least one of the plurality of channels; and the multichannel noise reduction module configured to remove the signal noise from a select channel in the multichannel signal based on i) the correlated noise and ii) at least one of the uncorrelated noise or the signal characteristic associated with the select channel.
