FIG. 1.

Noninvasive techniques to study angiogenesis postwounding. Images depict porcine burn wound at day 14 (early time point) and day 42 (late time point). (A) Laser speckle image showing blood perfusion in wound area. The dashed rectangle in laser speckle image represents the initial wound area. Scale bar indicates the gradient from high to low perfusion. (B) The wound depth and blood vessels can be visualized from the three-dimensional ultrasound image (43). The feeder blood vessels are in red. The scale bar indicates the gradient of in flow and out flow of blood. (C) The healing of wound can be accessed by elastography. The scale bar indicates the hardness and softness of tissue. The region within the arrows represents wound bed.
