1. A magnetocardiogram (MCG) system comprising:

  • a sensor unit including an array of M×

    M electromagnetic MCG sensors producing a sparse measurement output of M×

    M data values, said sparse measurement output constituting a first MCG image, said first MCG image being a two-dimensional (2D) image having M×

    M picture elements (e.g. pixels);

    a high resolution MCG image synthesizer for receiving said first MCG image and producing a higher resolution image representation of said first MCG image, said higher resolution image representation being a second MCG image of higher pixel density than said first MCG image, said second MCG image being a 2D image having P×

    P picture elements where P>

    M; and

    a de-noising image processing block for receiving said second MCG image and producing a de-noised lower resolution image representation of said second MCG image, said de-noised lower resolution image representation being a third 2D MCG image having M×

    M picture elements within a physical sensor area corresponding to the span of said M×

    M data values of said first MCG image, and said third MCG image having a reduced noise level as compared to said first MCG image.
