:::Issue recreated from Jira issue HZN-99:::

Hazen ghosting was used to analyse images from ECH Vida acceptance testing.

The values produced by hazen did not match those produced with ImageJ, and did not match the visible ghosting seen on the images. Values produced either underestimated ghosting or over estimated (for TE=120ms, NSA=1).

Hazen produced values and ghosting attached below.
