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.

Monitoring the Response of Port Wine Stain Birthmarks to Laser Therapy With Wide-field Functional Imaging Technologies
Monitoring the Response of PWS Birthmarks to Laser Therapy With Wide-field

The researcher at the Beckman Laser Institute develop non-invasive imaging modalities for assessment of port wine stain (PWS) during laser therapy treatment. The imaging modalities will be used to guide immediate retreatment of regions of persistent perfusion during the procedure.

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.
