Unique spectral signature of human cutaneous squamous cell carcinoma by photoacoustic imaging.

abstract：:Light delivery and monitoring during photodynamic therapy (PDT) is often limited by the need for a physical link between the light source, detectors and the treatment volume. This paper reports on the first in vivo experiments performed with a fully implantable telemetric system, designed for a rat glioblastoma model....
