The purpose of this study is to determine if a novel, unique, non-contact optical imaging device(camera) developed at the Beckman Laser Institute (BLI), called Modulated Imaging (MI), can help us customize Photodynamic therapy (PDT) treatment for patients with skin cancer. The device developed will be used to measure tissue optical properties that effect the PDT treatment process (e.g. spectral absorption and scattering coefficients, oxy- and deoxy-hemoglobin, water, melanin) and use that information to provide customized laser light treatment.

Detailed Description:

The current standard of care for skin cancer is excision, curettage and electrodesiccation and/or cryosurgery. These methods result in scarring, whereas PDT, on the other hand, offers the potential for enhanced treatment with less scarring. In spite of this advantage that PDT has over current techniques, it has still not achieved the consistent performance required to gain clinical acceptance.

The researchers want to use an imaging system that can characterize the tissue and photosensitizer optical properties and use that information to drive a treatment light projection system that can spatially optimize the light irradiance for personalized treatment, thus improving outcomes.
