Photonics SeminarGas in Scattering Media Absorption Spectroscopy Sune Svanberg, Ph.D. An overview of the new field of Gas in Scattering Media Professor Svanberg received his PhD in Physics from Göteborg University, Sweden in 1972. Since 1980 Professor Svanberg has been head of the Atomic Physics Division, Lund Institute of Technology, Sweden. In 1995 he became the director of the Lund Laser Center. Starting his research with atomic resonance spectroscopy, iProfessor Svanberg has been utilizing tuneable lasers for basic and applied atomic and molecular spectroscopy. Professor Svanberg is a fellow of the American Physical Society and the Optical Society of America. From 1997 until 2007 he was a Member of the Nobel Prize Committee for Physics serving as chairman for two years. In 2004 he was awarded the SKAPA Innovation Prize, in 2005 the W.E. Lamb Medal, and in 2006 the Celsius Gold Medal. Applications pursued by Professor Svanberg include environmental monitoring by laser radar and diode laser spectroscopy. He has been active for over 20 years in medical laser applications including fluorescence diagnostics of malignant disease, optical mammography and photodynamic treatment of tumors. Presently he and collaborators are developing advanced techniques for interstitial fiber-based therapy pursued interactively with spectroscopic diagnostics. |

Special Guest Dr. Katarina Svanberg Chief Oncologist at the Lund University Hospital Professor of Oncology at the Lund University, Lund Sweden Title: "Diagnostics and Treatment of Tumours using Laser Techniques" Summary: Applications of optical and laser spectroscopy to the medical field, including photodynamic therapy (PDT) and laser-induced fluorescence diagnostics (LIF) for cancer treatment and diagnostics, respectively, will be presented. Photodynamic therapy, when delivered as a superficial illumination to the target area, has a limitation due to restricted light penetration through tissue. One way of overcoming this is interstitial illumination (IPDT) in which the light is transmitted to the tumour via optical fibers. Interactive feed-back dosimetry is of importance for optimizing the modality and such a concept has been developed and will be presented. The most important prognostic factor for cancer patients is early tumour discovery. If malignant tumours are detected during the non-invasive stage, most tumours show a high cure rate of more than 90 %. There is a variety of conventional diagnostic procedures, such as X-ray imaging. More advanced results are given in computerized investigations, such as CT-, MRI- or PET-scanning. Laser-induced fluorescence (LIF) for tissue characterization is a technique that can be used for monitoring the biomolecular changes in tissue under transformation from normal to dysplastic and cancer tissue before structural tissue changes are seen at a later stage. The technique is based on UV or near-UV illumination for fluorescence excitation. The fluorescence from endogenous chromophores in the tissue alone, or enhanced by exogenously administered tumour seeking substances can be utilized. The technique is non-invasive and gives the results in real-time. LIF can be applied for point monitoring or in an imaging mode for larger areas, such as the vocal cords or the cervical area. The possibility to combine LIF and PDT will be discussed and illustrated with clinical examples from many specialties, such as dermatology, gynecology and laryngology. A new method where free gas (oxygen or water vapour) in the human sinus cavities is detected will be described. The technique is based on gas absorption spectroscopy in scattering media. The method can also be used to study the gas exchange in between the nasal cavity and the different sinuses in the facial region. Bio: Katarina Svanberg is an MD and a PhD. She works as a chief oncologist at the Lund University Hospital as well as a Professor of Oncology at the Lund University. Her research interests include laser-induced fluorescence detection of early malignancies as well as photodynamic therapy, in which field she very early introduced ALA for topical sensitisation. She is also involved in a new research field; GASMAS - Gas Detection in Scattering Media. Within this project the Lund group is developing non-intrusive techniques for detection of free gases within the human body, such as the gas exchange in the facial sinuses. Katarina Svanberg is the director of the Lund University Medical Laser Centre and is currently Vice President of the SPIE. She is also a fellow of the same society. She is author and co-author of more than 90 peer-reviewed papers, has been a co-organizer of conferences within the field and has presented numerous invited talks. She has a special interest in collaborations with countries in the developing world and has, together with collaborators, introduced PDT and fluorescence detection to Malaysia, Senegal and Lithuania, and is also involved in collaborations within other countries in Africa and in China. |
