The SilhouetteStar laser lines follow the surface of the wound-bed, enabling 3-D surface to be modelled.
Knowledge of where the laser lines will appear in the image, for a given distance between the camera and the wound, enables the system to automatically determine the distance of the camera from the wound and therefore the scale of the wound image.
Once the user has captured an image and traced the edges of the wound on the screen, Silhouette automatically calculates the measurements for area, depth and volume.
