Low-Cost Device Detects Skin Cancer with Light

Mar-12-19 A low cost, handheld laser probe detects melanoma tumors using lasers and light patterns.

Developed by a team from the University of British Columbia, the prototype device replaces expensive cameras and lenses with a laser that shines a light onto the target area. Based on the knowledge that light waves change as they move through objects, the system will identify the different scattering of the waves as they move through unhealthy tissue.

The device could be particularly useful in rural or impoverished areas. As PhD student Daniel Louie said, “We set out to develop this technology using inexpensive materials, so the final device would be easy to manufacture and widely used as a preliminary screening tool for skin cancer.”
