1. A method of forming an image of an article comprising the steps of:

  • propagating first waves in the article;

    measuring a response of the article to the first waves;

    forming a matched filter data set comprising first data points representing the response of the article to the first waves;

    generating second waves in the article at a plurality of generation positions on the article, which second waves propagate through the article;

    detecting a motion of the article at a plurality of detection positions to obtain second data points, the second data points forming a scan data set;

    multiplying the scan data set by the matched filter data set to generate a compensated data set comprising a plurality of third data points; and

    coherently summing the third data points in the compensated data set to form an image of the article.
