Book excerpt: Positron emission tomography (PET) is an imaging modality that can detect a contrast agent that preferentially accumulates on or inside diseased cells with concentrations as low as pico-mol/L. Since diseases typically begin on molecular and cellular levels, PET's sensitivity to fine molecular changes makes it essential for detection, staging, and treatment of oncological, cardiovascular, and neurological diseases. Moreover, PET is indispensable for basic research of biological processes, and pharmaceutical development. This dissertation presents mathematical and algorithmic techniques for increasing the safety, ac- curacy, and affordability of PET imaging. Particularly, it presents the first ever maximum likelihood expectation maximization (MLEM) algorithm for photon attenuation correction from PET emission data alone. This is the only existing technique that guarantees monotonic increase of PET image likelihood with estimation iterations. Moreover, the dissertation presents advances in stochastic modeling, inverse problems with incomplete data, numerical optimization, parallel computing, and graphics processing unit (GPU)-based formulation of the method, that reduce image estimation du- ration from 5 days to under an hour, by accelerating the algorithm by over 200-fold compared with single CPU-based formulation, and reducing its memory usage by 5-fold. Furthermore, the disser- tation shows how these advances could benefit other algorithms that model the imaging system in PET, SPECT, and CT. Particularly, it shows how they can accelerate single scatter simulation (SSS) by over 100-fold compared with single CPU-based formulation, and increase PET's geometrical sys- tem matrix compression used in the image reconstruction process by over 800-fold compared with today's state of the art methodology. Finally, using the advances described above, the dissertation presents the first ever MLEM algorithm for joint correction of photon attenuation and tissue-scatter from PET emission data alone.

Available in PDF, EPUB and Kindle. Book excerpt: Positron Emission Tomography (PET) has become an invaluable modality for in vivo imaging of molecular signatures of disease. The reconstruction algorithm for PET and the resulting image quality, however, have been limited by the large scale nature of the inverse problem, prohibiting sophisticated statistical algorithms from being used in practice. This work addresses the challenges in PET image reconstruction using state-of-the-art techniques in parallel computing, computer graphics, image processing, and convex optimization. More specifically, we reformulate the image reconstruction algorithm so that it can run efficiently on the massively parallel architecture of the Graphics Processing Unit (GPU). Memory access patterns and execution controls are optimized to maximize device resource utilization. Furthermore, strategies for extending the parallel processing to a cluster of GPUs is developed, taking the inter-node communication overhead into consideration. Finally, the drastic reduction of the computational cost enables practical applications of three methods for image quality and accuracy improvement, including using Point Spread Function (PSF) for resolution modeling, utilizing Compton scattered events in the detectors, and combining multiple reconstructions to achieve higher Signal-to-Noise Ratio (SNR) in motion correction tasks. Experiments show that the proposed methods are able to improve image quality and accuracy while reducing execution time. Part of the work has been integrated into the next generation Philips Time-of-Flight (ToF) PET systems.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents different approaches on multi-modality imaging with a focus on biomedical applications. Medical imaging can be divided into two categories: functional (related to physiological body measurements) and anatomical (structural) imaging modalities. In particular, this book covers imaging combinations coming from the usual popular modalities (such as the anatomical modalities, e.g. X-ray, CT and MRI), and it also includes some promising and new imaging modalities that are still being developed and improved (such as infrared thermography (IRT) and photoplethysmography imaging (PPGI)), implying potential approaches for innovative biomedical applications. Moreover, this book includes a variety of tools on computer vision, imaging processing, and computer graphics, which led to the generation and visualization of 3D models, making the most recent advances in this area possible. This is an ideal book for students and biomedical engineering researchers covering the biomedical imaging field.

This book was released on 2006-07-11 with total page 593 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a review of image analysis techniques as they are applied in the field of diagnostic and therapeutic nuclear medicine. Driven in part by the remarkable sophistication of nuclear medicine instrumentation and - crease in computing power and its ready and inexpensive availability, this is a relatively new yet rapidly expanding field. Likewise, although the use of nuclear imaging for diagnosis and therapy has origins dating back almost to the pioneering work of Dr G. de Hevesy, quantitative imaging has only recently emerged as a promising approach for diagnosis and therapy of many diseases. An effort has, therefore, been made to place the reviews provided in this book in a broader context. The effort to do this is reflected by the inclusion of introductory chapters that address basic principles of nuclear medicine instrumentation and dual-modality imaging, followed by overview of issues that are closely related to quantitative nuclear imaging and its potential role in diagnostic and therapeutic applications. A brief overview of each chapter is provided below. Chapter 1 presents a general overview of nuclear medicine imaging physics and instrumentation including planar scintigraphy, single-photon emission computed tomography (SPECT) and positron emission tomography (PET). Nowadays, patients’ diagnosis and therapy is rarely done without the use of imaging technology. As such, imaging considerations are incorporated in almost every chapter of the book. The development of dual-modality - aging systems is an emerging research field, which is addressed in chapter 2.
