This book covers the broad field of cellular, molecular, preclinical, and clinical imaging either associated with or combined with photodynamic therapy (PDT). It showcases how this approach is used clinically for cancer, infections, and diseases characterized by unwanted tissue such as atherosclerosis or blindness. Because the photosensitizers are also fluorescent, the book also addresses various imaging systems such as confocal microscopy and small animal imaging systems, and highlights how they have been used to follow and optimize treatment, and to answer important mechanistic questions. Chapters also discuss how imaging has made important contributions to clinical outcomes in skin, bladder, and brain cancers, as well as in the development of theranostic agents for detection and treatment of disease. This book provides a resource for physicians and research scientists in cell biology, microscopy, optics, molecular imaging, oncology, and drug discovery.

Michael R Hamblin Ph.D. is a Principal Investigator at the Wellman Center for Photomedicine at Massachusetts General Hospital, an Associate Professor of Dermatology at Harvard Medical School and is a member of the affiliated faculty of the Harvard-MIT Division of Health Science and Technology. His research interests lie in the areas of photodynamic therapy (PDT) for infections, cancer, and stimulation of the immune system, and in low-level light therapy (LLLT) for wound healing, arthritis, traumatic brain injury, neurodegenerative diseases and psychiatric disorders. He directs a laboratory of around a dozen post-doctoral fellows, visiting scientists and graduate students. His research program is supported by NIH, CDMRP, USAFOSR and CIMIT among other funding agencies. He has published 272 peer-reviewed articles, over 150 conference proceedings, book chapters and International abstracts and holds 8 patents. He is Associate Editor for 7 journals, on the editorial board of a further 12 journals and serves on NIH Study Sections. For the past 10 years Dr Hamblin has chaired an annual conference at SPIE Photonics West entitled Mechanisms for low level light therapy and he has edited the 10 proceedings volumes together with four other major textbooks on PDT and photomedicine. He has several other book projects in progress at various stages of completion. In 2011 Dr Hamblin was honored by election as a Fellow of SPIE.

Ying-Ying Huang, M.D., is a scientist in Dr. Michael Hamblin's lab in Wellman Center for Photomedicine at Massachusetts General Hospital, an Instructor of Dermatology at Harvard Medical School. She was trained as a dermatologist in China. She has been at MGH Wellman Center for 5 years. Her research interests lie in the areas of photodynamic therapy (PDT) for infections, cancer and mechanism of low level light therapy (LLLT) for traumatic brain injury.
