Primary Outcome Measures:
  • Method to monitor the response of laser treatment of port wien stain [ Time Frame: 1 week ] [ Designated as safety issue: No ]
    The proposed research is significant, because our image-guided surgery approach will show color images which will be used to adjust energy of the laser treatment, reducing ultimately the number of treatment sessions and the associated medical care burden.

Assessment of port wine stain birthmarks to laser therapy

Detailed Description:

The degree of photocoagulation caused by laser therapy will be assessed with LSI and SFDI.The imaging system operates by projecting low-power near-infrared structured light patterns on to the tissue of interest in a non-contact, reflection geometry and then capturing the reflectance with a CCD camera.The system can image the depth-resolved optical properties of in-vivo tissues, allowing rapid, non-invasive 3D visualization of sub-surface structures.
