Fig. 2.

Images of cardiac microvasculature acquired without (A) or with (C) the proposed stabilizer (triggered at the beginning of the “temporal stabilized window”; see Fig 3). The cross correlation (Pearson’s Coefficient) was calculated on the whole image frames acquired both without (B) or with (D) the stabilizer (0.25 and 0.8 respectively). Black dots instead indicate the correlation between image patches, within different frames, collected at the temporal stabilized window (W3; Fig. 3). Due to the reduced motion activity during this phase of the cardiac cycle, the value of cross correlation is increasingly higher for this portion of images (~ 1).
