Figure 4 of the Work (IMAGE) Universitat Pompeu Fabra - Barcelona Caption Registrations of thrombus deformation. The top and middle rows are images of two unfavourable evolution patients with aneurysm and the bottom row of a favourable evolution patient. For unfavourable evolution cases, most arrows point towards the outside of the aneurysm, while for favourable evolution cases, the arrows generally point towards the inside, representing shrinkage of the aneurysm. The colour of the arrows represents the magnitude of the displacement.
