Claim 7:
8. The imaging method according to claim 1, wherein in c) i), the low resolution reference images Li is estimated by down-sampling Hn to the dimensions of the low-resolution images Γi, warping Hn to a reference time frame i and blurring Hn according to the following equation:

Lni=DBMiHn+Ψi,

wherein H is a high-resolution image of the inspected object, Li is a set containing i=1, . . . , Nf low-resolution image frames of the object, Nf is the total number of frames, Mi is the motion vector fields (MVF) containing the spatio-temporal geometrical transformation of the object motion at frame i, B is a blurring kernel or point spread function (PSF) of the imaging system, D is a down-sampling kernel defining the difference in pixel size between H and Li, by combining several voxels of the grid into one, for example using linear interpolation, and Ψi an additive noise term.
