Temperature change. Steady-state fluid temperature change before (proximal to) and inside the expanded SMP foam during laser heating acquired by MRI. Images at laser powers of 0, 1, 3, 5, and 7 W are shown. Each column corresponds to a 2-mm slice as denoted by the numbered boxes overlaying the image of the area occupied by the foam device. Higher laser powers resulted in higher temperatures inside and outside the foam, with a maximum temperature change of 4°C at 7 W.
