Surface Imaging for Biomedical Applications

Based on hospital clinical trials examining the use of signal and image processing techniques, Surface Imaging for Biomedical Applications bridges the gap between engineers and clinicians. This text offers a thorough analysis of biomedical surface imaging to medical practitioners as it relates to the diagnosis, detection, and monitoring of skin conditions and disease. Written from an engineer's perspective, the book discusses image acquisition methods, image processing, and pattern recognition techniques. It focuses on a variety of techniques used in recent years for image processing and pattern recognition (principal component analysis, independent component analysis, singular value decomposition, texture modeling, inverse model analysis, polynomial surface fitting, and classification techniques), and considers interventional and non-invasive procedures used to diagnose skin-related disease. It examines the biological causation of four skin disorders (psoriasis, vitiligo, ulcer, and acne), provides basic terminologies in surface imaging, and details the outcome of various clinical observations and other research. It also details numerous measurement parameters related to surface imaging (body surface, skin color, tissue characteristic, thickness, roughness, volume of skin, and retinal changes). - Discusses the development of a psoriasis severity measurement tool - Provides material on assessing segmented repigmentation areas in vitiligo patients via VT-Scan - Introduces a volume ulcer assessment using non-invasive 3D imaging - Presents an automated system for acne grading that is based on capturing the images of various body parts using the DSLR camera - Includes the MATLAB® codes for various pattern recognition techniques applied during the assessment/measurement at the end of each chapter This interdisciplinary reference highlights the importance of disease diagnosis and monitoring, and is suitable for medical practitioners, biomedical engineers, and core image processing researchers.

Ahmad Fadzil Mohamad Hani heads the Centre for Intelligent Signal & Imaging Research (CISIR), a university centre of excellence under the Mission-Oriented in Biomedical Engineering at Universiti Teknologi PETRONAS, Perak, Malaysia. He graduated with a BSc (1st Class Honors) in electronic engineering in 1983, obtained his MSc in telematics in 1984, and his PhD in image processing in 1991 from the University of Essex, UK. He is a Fellow of the Academy of Sciences Malaysia and a Fellow of the Institution of Engineers Malaysia. His current research challenges are developing new analysis techniques for early osteoarthritis and drug addiction using MRI techniques and bio-optics for skin pigmentation analysis. Professor Fadzil has authored over 190 research articles in journals and conferences proceedings, granted several patents, and won several awards for his work.
