Imaging of buried structures

A system for obtaining an image of a buried structure in an object, comprising:

• a bounded infrared light source, the light source aligned with a visual light source, for partly irradiating said object by light;
• a camera device arranged for imaging an area of said object that is not irradiated by said bounded infrared light source for obtaining an infrared image of said buried structure from infrared light scattered off the buried structure and tissue surrounding the buried structure, and for obtaining a visual image of said object;
• and
• a processing device arranged for:
• providing a gradient analysis of said infrared image to detect edges of said buried structure;
• providing a gradient analysis to detect edges in said visual image;
• comparing edges detected during the gradient analysis of said visual image with edges detected during the gradient analysis of said infrared image;
• discarding edges detected in said infrared image that are also present in the edges detected in said visual image to render a modified infrared image;
• and
• combining said modified infrared image and visual image to depict edges of said buried structure in said second visual image.
