"ABSTRAKPerkembangan CT scan generasi multislice yang begitu pesat membuat pemeriksaan CT angiografi coroner sering dilaksanakan, akan tetapi pemberian informasi tentang dosis yang di terima pasien masih jarang dilakukan. Sehingga perlu dilakukan estimasi dosis pasien pada pemeriksaan CT angiografi coroner untuk mengetahui nilai dosis yang diterima oleh organ-organ yang sensitive terhadap radiasi seperti esophagus, paru-paru, payudara (pada wanita) dan jantung. Estimasi dosis dilakukan menggunakan program imPACT® dengan nilai nCTDIw didapat dari hasil pengukuran mengunakan detector pencil ion chamber menggunakan phantom acrilic 32 cm. Dari hasil estimasi di dapat dosis ekivalen yang diterima jantung 110 mSv ? 140 mSv, dosis efektif esophagus (thymus) 2,9 mSv ? 5.7 mSv, dosis efektif paru-paru 10 mSv -14 mSv, dosis efektif payudara 10 mSv ? 13 mSv dan total dosis efektif berkisar antara 31 mSv ? 42 mSv. Mengingat nilai total dosis efektif yang diterima pasien cukup tinggi, maka pasien CT angiografi coroner harus mendapatkan justifikasi yang kuat.

ABSTRACTThe Fast development of CT generation makes CT angiography coroner examination more frequence to be done, but the dose information of patient is rarely to be done. So it require to make patient dose estimation on CT angiography coroner examination. In order to know the dose receive by sensitive organ set of oesophagus, lung, brest and heart. Dose estimation is done using imPACT® program, using CTDI value obtain measurement using acrylic phantom with 32 cm diameter. From dose calculation the dose equivalent by heart is between 110 mSv - 140 mSv, and effective dose for oesophagus 2.9 mSv ? 5.7 mSv, lung 10 mSv ? 14 mSv and total effective dose between 31 mSv ? 42 mSv. Because effective dose receive by patient is very high, the CT angiography coroner patient must have a very strong justification. "

The third volume includes 79 papers organized in topical sections on diffusion imaging, from acquisition to tractography, image acquisition, segmentation and recognition, image registration, neuroimage analysis, analysis of microscopic and optical images, image segmentation, diffusion weighted imaging, computer-aided diagnosis and planning, and microscopic image analysis."

"The book provides a gradual, down to earth introduction to DICOM, accompanied by an analysis of the most common problems associated with its implementation. "

"Terahertz biomedical imaging has become an area of interest due to its ability to simultaneously acquire both image and spectral information. Terahertz imaging systems are being commercialized, with increasing trials performed in a biomedical setting. As a result, advanced digital image processing algorithms are needed to assist screening, diagnosis, and treatment. "Pattern recognition and tomographic reconstruction" presents these necessary algorithms, which will play a critical role in the accurate detection of abnormalities present in biomedical imaging. Terhazertz tomographic imaging and detection technology contributes to the ability to identify opaque objects with clear boundaries, and would be useful to both in vivo and ex vivo environments, making this book a must-read for anyone in the field of biomedical engineering and digital imaging."

"This book is intended as an introduction to neuroradiology and aims to provide the reader with a comprehensive overview of this highly specialized radiological subspecialty. One hundred illustrated cases from clinical practice are presented in a standard way. Each case is supported by representative images and is divided into three parts: a brief summary of the patient’s medical history, a discussion of the disease, and a description of the most characteristic imaging features of the disorder. The focus is not only on common neuroradiological entities such as stroke and acute head trauma but also on less frequent disorders that the practitioner should recognize."

"Written by internationally renowned experts, this volume is a collection of chapters dealing with imaging diagnosis and interventional therapies in neuroradiology and diseases of the spine. The different topics are disease-oriented and encompass all the relevant imaging modalities including X-ray technology, nuclear medicine, ultrasound and magnetic resonance, as well as image-guided interventional techniques. It represents a unique experience for residents in radiology as well as for experienced radiologists wishing to be updated on the current state of the art."

"Functional neuroradiology : principles and clinical applications, is a follow-up to Faro and Mohamed’s groundbreaking work, Functional (BOLD) MRI : basic principles and clinical applications. This new 49 chapter textbook is comprehensive and offers a complete introduction to the state-of-the-art functional imaging in Neuroradiology, including the physical principles and clinical applications of diffusion, perfusion, permeability, MR spectroscopy, positron emission tomography, BOLD fMRI and diffusion tensor imaging.With chapters written by internationally distinguished neuroradiologists, neurologists, psychiatrists, cognitive neuroscientists, and physicists, functional neuroradiology is divided into 9 major sections, including : physical principles of all key functional techniques, lesion characterization using diffusion, perfusion, permeability, MR spectroscopy, and positron emission tomography, an overview of BOLD fMRI physical principles and key concepts, including scanning methodologies, experimental research design, data analysis, and functional connectivity, eloquent cortex and white matter localization using BOLD fMRI and diffusion tensor imaging, clinical applications of BOLD fMRI in neurosurgery, neurology, psychiatry, neuropsychology, and neuropharmacology, multi-modality functional neuroradiology, beyond proton imaging, functional spine and CSF imaging, a full-color neuroanatomical brain atlas of eloquent cortex and key white matter tracts and BOLD fMRI paradigms.By offering readers a complete overview of functional imaging modalities and techniques currently used in patient diagnosis and management, as well as emerging technology, Functional Neuroradiology is a vital information source for physicians and cognitive neuroscientists involved in daily practice and research."
