Differential Microwave Imaging for Brain Stroke Followup
Figure 6
Followup of a postdiagnosis evolution of a hemorrhagic brain stroke via the proposed differential TSVD imaging approach in realistic conditions. (a) Scenario at the time (stroke diagnosis). The stroke is the red ellipse, while black contours represent its evolution at times , , and ; (b) normalized amplitude of the retrieved contrast at time ; (c) as (b) but at time ; (d) as (b) but at time . A gaussian noise with dB and a displacement of the probes has been assumed. The nonspecific reference head model is adopted in the inversion.
