Thorsten M. Buzug Bücher

Das Buch deckt neben den Themen der Entstehung, der Eigenschaften sowie Detektion von Röntgenstrahlen, die Entwicklungshistorie der Computertomographie, die elementaren Methoden der Signalverarbeitung und insbesondere die Signalverarbeitungsverfahren der Computertomographie ab. Hierbei wird Wert auf die ausführliche Darstellung der Mathematik der zwei- und dreidimensionalen Rekonstruktionsverfahren gelegt. Neben der ausführlichen Erklärung der theoretischen Konzepte wird auf die praktischen Randbedingungen der technischen Realisierung sowie auf die auftretenden Bildartefakte besonders eingegangen.

Das Institut für Medizintechnik der Universität zu Lübeck entwickelt innovative bildgebende Verfahren und Methoden der Bildverarbeitung sowie Simulationen biomedizinischer Prozesse. Ein interdisziplinäres Team aus Ingenieurwissenschaften, Physik, Informatik, Chemie und Mathematik untersucht sowohl physikalische Grundlagen, wie das Potenzial magnetischer Nanopartikelbildgebung in Kardiologie und Onkologie, als auch die Weiterentwicklung etablierter Verfahren in der Röntgen-basierten Tomographie (CT), Magnetresonanztomographie (MRT) sowie nukleardiagnostischen Verfahren wie SPECT und PET. Bei der Simulation biomedizinischer Prozesse liegt der Fokus auf multiphysikalischen Vorgängen, die durch Differentialgleichungen beschrieben werden, einschließlich Wachstumsprozessen maligner Tumore und Strömungsmodellen des Pharynx zur Therapie des Schlafapnoe-Syndroms. Ziel ist ein besseres Verständnis dieser Prozesse, um patientenindividualisierte Therapieansätze zu entwickeln. Das Institut wird die technischen Grundlagen der Bildgebung, wie Instrumentierung, Rekonstruktionsverfahren und Tracerentwicklung, in enger Kooperation mit Kliniken und der Industrie weiter vorantreiben. Zudem wird an der Integration molekularer Medizin mit der technischen Instrumentierung bildgebender Verfahren gearbeitet.

Focusing on the intricate development of X-ray technology, this book delves into the historical milestones of computed tomography (CT) and its mathematical foundations. It covers essential topics such as X-ray generation, photon interactions, and signal processing, providing a comprehensive introduction to CT principles. Detailed derivations of reconstruction algorithms for both 2D and modern 3D cone-beam systems are emphasized, along with analysis of CT artifacts and practical considerations like dose management. It's tailored for graduate students and seasoned professionals in related fields.

This volume provides an overview of X-ray technology and the historical development of modern CT systems. The main focus of the book is a detailed derivation of reconstruction algorithms in 2D and modern 3D cone-beam systems. A thorough analysis of CT artifacts and a discussion of practical issues such as dose considerations give further insight into current CT systems. Although written mainly for graduate students, practitioners will also benefit from this book.

In this book, research and development trends of physics, engineering, mathematics and computer sciences in biomedical engineering are presented. Contributions from industry, clinics, universities and research labs with foci on medical imaging (CT, MRT, US, PET, SPECT etc.), medical image processing (segmentation, registration, visualization etc.), computer-assisted surgery (medical robotics, navigation), biomechanics (motion analysis, accident research, computer in sports, ergonomics etc.), biomedical optics (OCT, soft-tissue optics, optical monitoring etc.) and laser medicine (tissue ablation, gas analytics, topometry etc.) give insight to recent engineering, clinical and mathematical studies.

Additive manufacturing, often referred to as 3D printing, has long since proven its suitability for everyday use. However, many questions remain unanswered for use in medicine. Complex melting and hardening processes take place during the layer-by-layer construction of medical devices from liquid or solid materials, the physical-chemical modelling of which is often still pending, so that a discussion forum is to be given at AMMM on topics relating to the achievable precision and the expected technical properties of the medical devices produced in this way. Questions about the precision and interaction of the printed materials with their future application matrix are important for all industries. However, these requirements are of particular interest in the medical environment, where biological compatibility and long-term stability are of particular importance. Medical technology companies are also faced with the question of whether this modern manufacturing technology should only be used in prototype and individualized sample development or also in series production. Costs and benefits have to be assessed very individually. AMMM 2019 will focus on these questions, with particular emphasis on the medical device regulation of patient-specific devices.

Magnetic Particle Imaging (MPI) is a novel imaging modality that uses various static and oscillating magnetic fields to image the spatial distribution of superparamagnetic iron oxide nanoparticles (SPIOs) with high sensitivity, no tissue background, and no ionizing radiation. The method exploits the non-linear magnetization behavior of the SPIOs, and has shown great potential to surpass current in vivo imaging modalities in terms of sensitivity, safety, quantitation, and spatio-temporal resolution. MPI is well suited for clinical applications such as angiography, cancer imaging, and inflammation imaging; as well as research applications such as stem cell imaging and small animal imaging.

MPI is well suited for clinical applications such as angiography, cancer imaging, and inflammation imaging; as well as research applications such as stem cell imaging and small animal imaging. Since the first workshop in 2010, the International Workshop on MPI (IWMPI) has been the premier forum for researchers working in the MPI field. The workshop aims at covering the status and recent developments of both the instrumentation and the tracer material, as they are equally important in designing a well performing MPI system. The main topics presented at the workshop include hardware developments, image reconstruction and systems theory, nanoparticle physics and theory, nanoparticle synthesis, spectroscopy, patient safety, and medical/research applications of MPI. Over the years, the attendance to the workshop increased from around 70 attendees in 2010 to over 200 researchers this past year.
