"We developed a gamma ray detector with an LuAG:Pr scintillator and an avalanche photodiode as a detector for a positron emission tomography (PET) system. Studies have been performed on the influences of gamma irradiation on application-specific integrated circuit (ASIC) preamp boards used as a detector module. As a device used in nuclear environments for substantial durations, the ASIC has to have a lifetime long enough to ensure that there will be a negligible failure rate during this period. These front-end systems must meet the requirements for standard positron emission tomography (PET) systems. Therefore, an equivalent noise charge (ENC) experiment is needed to measure the front-end system's characteristics. This study showed that minimum ENC conditions can be achieved if a shorter shaping time could be applied."

"Over the past decade, PET-CT has achieved great success owing to its ability to simultaneously image structure and function, and show how the two are related. More recently, PET-MRI has also been developed, and it represents an exciting novel option that promises to have applications in oncology as well as neurology. The first part of this book discusses the basics of these dual-modality techniques, including the scanners themselves, radiotracers, scan performance, quantitation, and scan interpretation. As a result, the reader will learn how to perform the techniques to maximum benefit. The second part of the book then presents in detail the PET-CT and PET-MRI findings in cancers of the different body systems. The final two chapters address the use of PET/CT in radiotherapy planning and examine areas of controversy. The authors are world-renowned experts from North America, Europe, and Australia, and the lucid text is complemented by numerous high-quality illustrations."

"The horizons of sophisticated imaging have expanded with the use of combined positron emission tomography (PET) and computed tomography (CT). PET-CT has revolutionized medical imaging by adding anatomic localization to functional imaging, thus providing physicians with information that is vital for the accurate diagnosis and treatment of pathologies. Since the integration of PET and CT several years ago, PET/CT procedures are now routine at leading medical centers throughout the world. This has increased the importance of nuclear medicine physicians acquiring a broad knowledge in sectional anatomy for image interpretation. The Atlas of Sectional Radiological Anatomy for PET/CT is a user-friendly guide presenting high-resolution, full-color images of anatomical detail and focuses solely on normal FDG distribution throughout the head & neck, thorax, abdomen, and pelvis, the primary sites for cancer detection and treatment through PET/CT.

"This book presents a new FPGA architecture known as tree-based FPGA architecture, due to its hierarchical nature. This type of architecture has been relatively unexplored despite their better performance and predictable routing behavior, as compared to mesh-based FPGA architectures. In this book, we explore and optimize the tree-based architecture and we evaluate it by comparing it to equivalent mesh-based FPGA architectures."

"ABSTRAK
Transformasi Fourier merupakan salah satu contoh dari teknik analisa transformasi, yang digunakan untuk menyederhanakan solusi dari suatu masalah komputasi. Transformasi Fourier dari sebuah gelombang diperlukan untuk memisahkan gelombang tersebut menjadi sejumlah gelombang sinusoidal dengan frekuensi yang berbeda.
Sebuah algortima yang efisien, aitu suatu Transformasi Fouerier cepat (Fast Fourier Transform - FFT) telah dikembangkan. FFT ini digunakan untuk menghitung DFT (Discrete Fourier Transform). Dengan demikian telah terjadi perubahan yang besar dalam menganalisa berbagai cabang ilmu pengetahuan (science). Prosesor FFT yang terkecil mempunyai dua titik transformasi (N=2).
Pada penelitian ini dibahas tentang implementasi tata letak VLSI pada perancangan prosesor FFT untuk titik transformasi sebanyak dua buah (N=2). Implementasi ini dilakukan pada kertas milimeter dan hasilnya dianalisa secara teoritis"

"Systems on Chip (SoC) for communications, multimedia and computer applications have recently received much international attention; one such example being the single-chip transceiver. Modern microelectronic design adopts a mixed-signal approach as a complex SoC is a mixed-signal system including both analogue and digital circuits. Automatic testing becomes crucially important to drive down the overall cost of next generation SoC devices.
Test and fault diagnosis of analogue, mixed-signal and RF circuits, however, proves much more difficult than that of digital circuits due to tolerances, parasitics and nonlinearities and therefore, together with challenging tuning and calibration, remains the bottleneck for automatic SoC testing.
This book provides a comprehensive discussion of automatic testing, diagnosis and tuning of analogue, mixed-signal and RF integrated circuits, and systems in a single source. The book contains eleven chapters written by leading researchers worldwide. As well as fundamental concepts and techniques, the book reports systematically the state of the arts and future research directions of these areas. A complete range of circuit components are covered and test issues are also addressed from the SoC perspective.
An essential reference companion to researchers and engineers in mixed-signal testing, the book can also be used as a text for postgraduate and senior undergraduate students.
