Terahertz imaging for biomedical applications: pattern recognition and tomographic reconstruction

Terahertz biomedical imaging has become an area of interest due to its ability to simultaneously acquire both image and spectral information. Terahertz imaging systems are being commercialized, with increasing trials performed in a biomedical setting. As a result, advanced digital image processing algorithms are needed to assist screening, diagnosis, and treatment. 'Pattern Recognition and Tomographic Reconstruction' presents these necessary algorithms, which will play a critical role in the accurate detection of abnormalities present in biomedical imaging. Terhazertz tomographic imaging and detection technology contributes to the ability to identify opaque objects with clear boundaries, and would be useful to both in vivo and ex vivo environments, making this book a must-read for anyone in the field of biomedical engineering and digital imaging. Introduces terahertz radiation techniques and provides a number of topicalexamples of signal and image processing, as well as machine learning. Presents the most recent developments in an emerging field, terahertz radiation. Utilizes new methods of digital imaging that would be useful in medical screening,diagnosis, and treatment INDICE: Introduction and Motivation to Terahertz Radiation. Terahertz Sources and Detectors.
