""The book offers a comprehensive and user-oriented description of the theoretical and technical system fundamentals of computed tomography (CT) for a wide readership, from conventional single-slice acquisitions to volume acquisition with multi-slice and cone-beam spiral CT. It covers in detail all characteristic parameters relevant for image quality and all performance features significant for clinical application. Readers will thus be informed how to use a CT system to an optimum depending on the different diagnostic requirements. This includes a detailed discussion about the dose required and about dose measurements as well as how to reduce dose in CT. All considerations pay special attention to spiral CT and to new developments towards advanced multi-slice and cone-beam CT. For the third edition most of the contents have been updated and latest topics like dual source CT, dual energy CT, flat detector CT and interventional CT have been added. The enclosed CD-ROM again offers copies of all figures in the book and attractive case studies, including many examples from the most recent 64-slice acquisitions, and interactive exercises for image viewing and manipulation. This book is intended for all those who work daily, regularly or even only occasionally with CT: physicians, radiographers, engineers, technicians and physicists. A glossary describes all the important technical terms in alphabetical order. The enclosed DVD again offers attractive case studies, including many examples from the most recent 64-slice acquisitions, and interactive exercises for image viewing and manipulation"--Back cover."

"Principles of Computerized Tomographic Imaging provides a comprehensive, tutorial-style introduction to the algorithms for reconstructing cross-sectional images from projection data and contains a complete overview of the engineering and signal processing algorithms necessary for tomographic imaging. In addition to the purely mathematical and algorithmic aspects of these algorithms, the book also discusses the artifacts caused by the nature of the various forms of energy sources that can be used for generating the projection data. Kak and Slaney go beyond theory, emphasizing real-world applications and detailing the steps necessary for building a tomographic system.
Since the fundamental aspects of tomographic reconstruction algorithms have remained virtually the same since this book was originally published, it is just as useful today as it was in 1987. It explains, among other things, what happens when there is excessive noise in the projection data; when images are formed from insufficient projection data; and when refracting or diffracting energy sources are used for imaging. Anyone interested in these explanations will find a wealth of useful information in this book."

"With a special emphasis on the complementary nature of anatomic and functional cardiac data, this book ensures physicians develop the skills they need to interpret cardiac CT images. New chapters address evaluation of the thoracic aorta, congenital heart disease in the adult, triple rule-out CT angiography, and the latest innovations in cardiac CT. "

"This book provides a unified view of tomographic techniques, a common mathematical framework, and an in-depth treatment of reconstruction algorithms. It focuses on the reconstruction of a function from line or plane integrals, with special emphasis on applications in radiology, science, and engineering. The Mathematics of Computerized Tomography covers the relevant mathematical theory of the Radon transform and related transforms and also studies more practical questions such as stability, sampling, resolution, and accuracy. Quite a bit of attention is given to the derivation, analysis, and practical examination of reconstruction algorithms, for both standard problems and problems with incomplete data."

"Electrical Impedance Tomography EIT adalah metode pencitraan yang mampu memperkirakan distribusi impedansi listrik di bagian dalam objek. Sistem EIT yang dibuat lebih sederhana dan portabel berbasis Mikrokontroler dan menggunakan 32 elektroda. Dari pasangan elektroda diinjeksikan arus bolak-balik 3 mA dan diukur beda voltase pada pasangan elektroda lain. Data pengukuran voltase dikirim ke MATLAB dan software EIDORS, data tersebut akan direkonstruksi menjadi citra objek dua dimensi. Objek dengan ukuran 4 cm2 atau lebih dapat direkonstruksi oleh sistem EIT dengan noise citra skala normal. Posisi objek dicitrakan cukup akurat dengan pergeseran rata-rata sebesar 0,69 cm namun luas objek belum dapat dicitrakan dengan akurat. Keakurasian citra objek lebih besar ketika letak objek dekat dengan elektroda, ukuran objek besar, dan diinjeksikan arus dengan frekuensi 100KHz dan 200KHz.

Electrical Impedance Tomography EIT is an imaging method that is able to estimate electrical impedance distribution inside of an object. EIT system is developed by using 32 electrodes and microcontroller based. From a pair of electrodes, sinusiodal curent 3mA is injected and diffrence voltage of another pair of electrodes is measured. Voltage measurement datas is sent to MATLAB and EIDORS software, the data is used to reconstruct two dimensions image. An Object size of 4 cm2 or more can be recontructed by EIT system with normal noise. Object position is high accurately reconstructed with mean displacement 0.69 cm but object area cannot be accurately reconstructed. Object rsquo s image more accurate when object rsquo s position closer to electrodes, bigger object rsquo s size, and current injected with frequency 100 KHz and 200KHz."

"Penelitian ini menyampaikan sebuah desain sensor 12 Channel yang dirotasi pada ECVT sebagai ide dasar untuk perbaikan citra hasil rekontruksi. Sensor dibuat dengan menambahkan motor pada bagian atasnya untuk dapat memutar dan pada bagian samping untuk menaikan dan menurunkan sensor. Pengaruh dari rotasi dan translasi sensor dianalisa dengan membandingkan dengan sensor konvensional. Metode yang digunakan adalah coefficient correlation (cc) dan metode rekontruksi menggunakan LBP untuk mengetahui pengaruh dari rotasi dan translasi saja. Dari hasil eksperimen dapat disimpulkan bahwa terdapat perbedaan antara sensor rotasi dengan nilai cc 0.76 dan 0.64 pada sensor konvensional, atau terjadi peningkatan kualitas citra sebesar 12%.

The research proposes a design of 12-channel rotary sensor for electrical capacitance volume tomography (ECVT) toward improvement in image reconstruction result. Sensor was assembled by attaching motors at upper section to rotate in radial; also at side to move up and down. Effects of rotating and translating the sensor has been analyzed in comparison to conventional sensory system. Correlation coefficient (CC) method and linear back-projection (LBP) were used to observe the performance on rotation-translation. Experiments show a difference between rotation with CC of 0.76 and conventional with CC of 0.64. In other words, image quality is improved by 12%."
