2. Clinical & Biomedical Spectroscopy & Imaging

Spectroscopic methods have become most valuable tools for both clinical diagnostics and biomedical research applied to in vivo tissue monitoring and the investigation on the molecular scale of excised samples. In clinical diagnostics, optical spectroscopy provides detailed structural and functional information on organs, tissues and body liquids. Basic biomedical applications include the detailed investigation of tissues and cells down to the level of single molecules, helping to understand the principles of cellular and sub-cellular processes in the early transformation of normal to diseased tissue, such as when malignant tumours are developed.

The conference provides an interdisciplinary platform for physicians, physicists, biologists, chemists and related researchers in order to strengthen an integrated and holistic approach of understanding normal tissue development and the genesis of diseases in order to be able to ultimately develop new, efficient treatment modalities.

Contributed papers are solicited, but not limited, to the following areas, using optical spectroscopy methods, e.g. fluorescence, autofluorescence, linear and nonlinear Raman, NIR, polarization, back-reflectance, and light scattering spectroscopy, and combined approaches (multimodal imaging):

3. Diffuse Optical Imaging

The study of diffuse light imaging in tissue continues to provide new insight into the structural and functional properties of tissues that are not easily accessed by alternative methods. The research and development of systems that exploit this approach has led to clinical prototype systems that are used in basic science and medical research. Scientific applications range from the study of cerebral physiology to cancer patho-physiology in both animals and humans. Medical applications being explored encompass detection and diagnosis of breast cancer, brain cancer, cognitive neuroscience, stroke, hemorrhages, brain and muscular oxygenation, peripheral vascular diseases and joint diseases as well as establishing novel methods in drug discovery and tracking. Integration of diffuse light imaging into existing clinical instrumentation is a key area of development, and combining diffuse light imaging with new contrast agents or other imaging modalities are also emerging as major growth areas.

Further improvement in these and other application areas relies on continued advancement in the theory of radiation transport through random media, in data analysis and image reconstruction algorithms, and in instrumentation design.

4. Opto-Acoustic Methods and Applications

In the last decade optoacoustic (photoacoustic) imaging has grown significantly to a powerful optical imaging platform suitable for basic research, clinical translation, and drug discovery. Advances in the system design, laser and ultrasound detection technology in conjugation with the ability to visualize a large range of anatomical, functional and molecular bio-markers have led to new and exciting ways of visualizing structure and function in biological tissue.

One of the promising aspects of the optoacoustic methodology is its versatility, manifested in the numerous distinct imaging concepts employed in it: multispectral imaging, nonlinear imaging, real-time imaging, tomography, microscopy, endoscopy, etc. Label-free imaging of functional parameters of vasculature including hemoglobin oxygenation and oxygen metabolism can be combined with simultaneous detection of exogenous molecular agents to provide more complete views of pathologies at appropriate scales from optical diffraction-limited microscopy to depths of several centimeters.

Additionally, the ability to detect nanoparticles of interest by means of their optical absorption enables unique in vivo visualization This emerging field of the imaging sciences integrates many scientific disciplines from physics and engineering to chemistry and biotechnology. It is the aim of this conference to bring together those disciplines which make up the optoacoustic field with particular emphasis on development and adaption of optoacoustic technology to enable novel biological and clinical applications.

5. Novel Biophotonics Techniques and Applications

Aside from the well-recognised avenues of biomedical optics for diagnostics, therapeutics and analytics/microscopy, a number of novel and highly promising approaches are under development. These new techniques often rely on the confluence of two or more diverse fields, drawing on their complementarity in order to overcome the inherent complexity and heterogeneity of biological tissues. Examples include photoacoustic spectroscopy, use of MRI to constrain optical tomographic reconstructions, PDT sterilization of surgical margins and the emerging role of photodiagnostics in monitoring and guiding therapies in real time (“theragnostics”). These hybrid approaches are driven by task-specific requirements of a particular application. Moreover, a number of new ideas are being investigated based on new methodologies, physical basis, instrument development, integration techniques and data analysis. This conference will present a highly interdisciplinary discussion forum of interest to instrument designers, sensor builders, basic and applied clinical researchers, and other scientists interested in exploring novel directions in biophotonics.

7. Medical Laser Applications and Laser-Tissue Interactions

Medical laser application is a broad area for research and development with the vision of improving clinical therapeutic procedures or to extend into new fields for lasers in medical use. Novel biomedical laser applications are emerging due to the advent of new types of lasers that widen the possible spectrum of laser-tissue interactions to improve the target-oriented precise application of laser radiation in clinical practice. Laser light applications include the whole range of non-thermal to thermal reactions up to ionization effects either on the macro-scale, e.g. soft tissue smoothing without ablation, or on the micro scale, e.g. selective retina therapy, to the nano-scale for surgery within cells, as well as short-pulsed laser applications to treat soft and hard tissue in patients. In addition to that new laser light application techniques as well as innovative medical keyhole techniques such as laser assisted NOTES (Natural Orifice Transluminal Endoscopic Surgery) are under investigation.

Highly sophisticated targeting strategies including endogenous or applied chromophores as well as conjugation of chromophores or nanoparticles with antibodies pave the way for new treatment modalities. Furthermore combination therapies such as the synergetic use of photodynamic therapy and immunomodulatory or antiseptics are encouraging new fields for research and clinical studies.

Improved understanding of biological reactions triggered by laser radiation interacting with natural absorbing sites, targeting molecules, photosensitizers, or nanoparticles will lead to progress in the creation of minimally-invasive clinical laser light applications or assist in elucidating particular immunological responses from the tissue.

Theoretical considerations and modeling of laser light distribution in tissue with subsequent energy transfer and tissue interactions constitute a solid basis for therapy planning in patients, particular if combined by improved light delivery and monitoring techniques.

This conference will provide an interdisciplinary forum for scientists, engineers, technicians, and medical doctors using laser assisted treatment modalities to discuss the progress in all these topics. The forum joins presentations from in-vitro investigations up to clinical studies of new laser light irradiance in the range of 10-3 – 1018 Wcm-2 to lead to actual clinical and medical questions where laser assisted techniques can play an important role in future.

8. Neurophotonics

Understanding the brain, its circuitry and its ability to process information, remains one of the grand challenges in biomedical research. The use of light has revolutionized this quest by providing efficient methods to image the brain, from individual neurons to its vascular networks and blood flow. Light combined with recent advances in biochemistry and genetic engineering has allowed neurophotonics to harness ever more powerful methods that manipulate and probe processes in neurons and their behaviour in a network. These include novel ways to provide high-speed, multi-modal and high-resolution 3D brain imaging and multi-site photostimulation of neurons via photolysis, infra-red stimulation or optogenetics. Laser axotomy/dendrotomy operation, furthermore, is opening new frontiers in understanding repair mechanisms: in this case, dendrite or axon cutting, as well as spine ablation, is an interesting approach to study neuroplasticity also in transgenic knock out mouse model or under some pharmacological treatment. Further areas of neurophotonics include monitoring brain function in human adults and infants using near infrared spectroscopy and tomography approaches, as well as the use of light for photodynamic therapy. Finally, multimodal imaging represents another frontier, allowing different features of the functioning brain to be assessed by in parallel.

This conference will provide a forum for physicists, optical engineers and neuroscientists to report current developments and discuss further ventures on the use of light to study the brain.
