A test of the accuracy of the centre-of-mass map concept based on a (ϕ, χ) scan and using the same phantom as in Fig. 4. (a) The model qi,1 field and (c) the corresponding qi,1 field derived from the COM mapping of DFXM images. (b) The model qi,2 field and (d) the corresponding qi,2 field derived from the COM mapping of DFXM images. |
