Photoacoustic imaging (PAI) is an emerging non-invasive imaging modality that integrates the advantages of deep ultrasound penetration and high optical contrast. It provides better resolution than pure ultrasonic imaging and deeper penetration than pure optical imaging. Hence, it is opening new frontiers in diagnostic imaging. Photoacoustic Imaging - Principles, Advances and Applications, provides interested readers with the principle knowledge, advanced methodologies, and new applications associated with PAI technology. Written by expert researchers, chapters cover such topics as the generation and detection of photoacoustic signals, sound source localization, image reconstruction and formation, and application of PAI in gastroenterology and ophthalmology.

Photoacoustic and Photothermal Spectroscopy: Principles and Applications introduces the basic principles, instrumentation and major developments in the many applications of Photoacoustic and Photothermal Spectroscopy over the last three decades. The book explains the processes of sound generation by periodic optical excitation and ultrasonic generation by pulsed laser excitation and describes the workings of photoacoustic cells equipped with microphones and piezoelectric transducers. Photoacoustic imaging (PAI) is one of the fastest-growing imaging modalities of recent times. It combines the advantages of ultrasound and optical imaging techniques. These non-invasive and non-destructive techniques offer many benefits to users by enabling spectroscopy of opaque and inhomogeneous materials, (solid, liquid, powder, gel, gases) without any sample preparation, and more. - Written in a non-mathematical, simple-to-read manner - Presents recent developments in the field, along with the scope of future progress, including up-to-date references - Includes detailed illustrations, such as equipment layout, spectra, experimental setups, tables, photographs, and more

Gas-phase photoacoustics are treated comprehensively for the first time in this book. Review articles by leading scientists in the respective research areas introduce their fields, review present knowledge and conclude with the latest developments and future prospects. Topics covered include the theory of photoacoustics in the frequency and time domains, acoustic resonator models, a great variety of experimental setups and techniques, studies of spectrocopy and fundamental kinetic processes such as energy transfer and chemical reactions, and applications such as air and exhaust monitoring and trace gas detection in biology and agriculture. The book will interest newcomers to photoacoustics, since it gives an overview of the important directions of current research and detailed descriptions of experimental methods. It will also be a valuable source of information for those already involved in photoacoustic research due to its clear presentation of theory and experimental results. All relevant literature references in this rapidly expanding field of laser applications are included.

The concept of photoacoustic tomography (PAT) emerged in the mid-1990s, and the field of PAT is now rapidly moving forward. Presenting the research of a well-respected pioneer and leading expert, Photoacoustic Tomography is a first-of-its-kind book covering the underlying principles and practical applications of PAT in a systematic manner. Written in a tutorial format, the text: Addresses the fundamentals of PAT, the theory on photoacoustic effect, image reconstruction methods, and instrumentation Details advanced methods for quantitative PAT, which allow the recovery of tissue optical absorption coefficient and/or acoustic properties Explores the development of several image-enhancing schemes, including both software and hardware approaches Examines array-based PAT systems that are the foundation for the realization of 2-D, 3-D, and 4-D PAT Discusses photoacoustic microscopy (PAM) and combinations of PAT/PAM with other imaging methods Considers contrast-agents-based molecular PAT, with both nontargeted and cell receptor–targeted methods Describes clinical applications and animal studies in breast cancer detection, osteoarthritis diagnosis, seizure localization, intravascular imaging, and image-guided cancer therapy Photoacoustic Tomography is an essential reference for graduate students, researchers, industry professionals, and those who wish to enter this exciting field.
