This is an interdisciplinary book that presents the applications of novel laser spectroscopy and imaging techniques for the detection of cancers recently developed by some of the world's most renown researchers. The book consists of three parts and a total of 16 chapters. Each chapter is written by leading experts who are actively seeking to develop novel spectroscopic and analytical methods for cancer detection and diagnosis.In Part I, the authors present fundamentals on optics, atoms and molecules, biophysics, cancer and machine learning. These chapters are intended for those who are not experts in the field but wish to learn about fundamentals' aspects of some of the key topics that are addressed in this book. Particular attention has been given to providing key references for those who wish to go further into the fundamental aspects of atoms and molecules, light-matter interaction, optical instrumentation, machine learning and cancer.In Part II, the authors present key applications of various laser spectroscopic methods in cancer diagnosis. They have provided recent progress in cancer diagnostics obtained by combining laser spectroscopy and machine learning for the analysis of the spectra acquired from biomedical tissues and biofluids.In Part III, the authors present chapters that discuss key developments in the applications of various laser imaging techniques for cancer detection.This is one of the few books that addresses cancer detection and diagnosis using laser spectroscopic and imaging tools with an eye on providing the reader the scientific tools, including machine learning ones.

Herein we demonstrate the construction of the first reported fluorescence animal tomographer for molecular investigations of cancer-associated expression patterns. Using inversion techniques that account for the diffuse nature of photon propagation in tissue and near infrared fluorescent molecular beacons we were able to obtain three-dimensional in-vivo images of cathepsin B expression of orthopic gliomas. We demonstrate that fluorescent probes, activated by carcinogenesis, can be detected with high positional accuracy and high sensitivity in deep tissues, that molecular specificities of different beacons towards enzymes can be resolved, and that tomography of beacon activation is linearly related to enzyme concentration. The tomographic imaging method offers a range of new capabilities for studying biological function using fluorescent chemical sensors, for identifying molecular expression patterns via multispectral imaging and for continuously monitoring drug therapies. It is envisaged that molecular sensing will significantly improve the detection capacity of early cancer since malignancy identification is based on the molecular signals responsible for carcinogenesis and not on structural or functional tissue changes inflicted by well-formed cancers that are currently targeted by traditional medical imaging techniques.

This book provides an in-depth description and discussion of different multi-modal diagnostic techniques for cancer detection and treatment using exact optical methods, their comparison, and combination. Coverage includes detailed descriptions of modern state of design for novel methods of optical non-invasive cancer diagnostics; multi-modal methods for earlier cancer diagnostic enhancing the probability of effective cancer treatment; modern clinical trials with novel methods of clinical cancer diagnostics; medical and technical aspects of clinical cancer diagnostics, and long-term monitoring. Biomedical engineers, cancer researchers, and scientists will find the book to be an invaluable resource. Introduces optical imaging strategies; Focuses on multimodal optical diagnostics as a fundamental approach; Discusses novel methods of optical non-invasive cancer diagnostics.

This thesis describes the design, development, characterisation and clinical translation of three novel devices for optical endoscopic imaging. Over the past decade, rapid innovation in optics and photonics has led to the availability of low-cost and high-performance optical technologies that can be exploited for biomedical applications, but relatively few have been translated into clinic. The work presented outlines for the first time, a comprehensive analysis of the common barriers and unique challenges associated with the translation of optical imaging techniques. To assist developers streamline translation of optical imaging devices in future, a roadmap to clinical translation is outlined, and key translational characteristics are defined. Guided by these, subsequent development of endoscopic devices resulted in preparation and approval of endoscopes for first in human trials in the oesophagus, for early detection of cancer, and in the brain, for delineation of tumour during surgical resection. The thesis culminates in the presentation of results from the first in human use of a compact multispectral endoscope for imaging endogenous tissue contrast in the oesophagus. With continuation of the work as outlined at the end of this thesis, the novel techniques described have the potential to improve the standard of care in their respective indications.

To describe principles of optical imaging including chemistry and physics of fluorescence, limitations/advantages of optical imaging compared to metabolic and anatomic imaging. Describe hardware adapted for small animal imaging and for clinical applications: endoscopes and operative microscopes. Outline FDA approved and newer optical imaging probes. Include discussion of chemistry and linkage to other proteins. Review current techniques to image cancer and the development of techniques to specifically image cancer cells. Review use of exploiting differences in tissue autofluorescence to diagnose and treat cancer. Include agents such as 5-aminoleculinic acid. Review mechanisms that require proteolytic processing within the tumor to become active fluorophores. Review use of cancer selective proteins to localize probes to cancer cells: include toxins, antibodies, and minibodies. Introduction of plasmids, viruses or other genetic material may be used to express fluorescent agents in vivo. This chapter will review multiple vectors and delivery mechanisms of optical imaging cassettes.Preclinical investigations into the use of optical contrast agents for the detection of primary tumors in conventional and orthotopic models will be discussed. Preclinical investigations into the use of optical contrast agents for the detection of metastatic tumors in mouse models will be discussed. Use of targeted and non-specific optical contrast agents have been used for the detection of sentinel lymph node detection. These applications and how they differ from other applications will be discussed. Because of the unique difficulty of identifying tumor from normal tissue in brain tissue, a separate chapter would be needed. More clinical data is available for this cancer type than any other. Discussion of potential clinical applications for optical imaging and an assessment of the potential market.
