This book was released on 2012-12-06 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since its presentation by G.N. Hounsfield at the second Congress of the European Association of Radiology in Amsterdam in June 1971, "Computerised Trans verse Axial Tomography" which became later on "Computerised Axial Tomography (CAT)" then simply "Computed Tomography (CT)" has developed extremely rapidly. Many papers have appeared in a short time, pointed out the substantial advantages of this new technique and precisely describing the characteristic images obtained. The number of devices is already considerable and their evolution tends towards the improvement of the quality of images and the shortening of exploration time. It is not an exaggeration to say that there is no longer any Neuroradiology without computed tomography. Does that mean that this new technique is infallible and that classical neuroradiological techniques are due to disappear in the near future? Experience shows that if certain techniques, such as gas encephalography, 'are less frequently employed since CT, others, such as cerebral angiography, are still commonly required.

Download or read book Dynamic Computed Tomography written by Claus Claussen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors present their experience in more than seven years of dynamic computed tomography in clinical practice. Time density curves and characteristic examples in specific regions of interest enrich the presentation. Dynamic computed tomography makes an important contribu tion to the diagnosis and evaluation of a pathologic process: the demonstration of the dynamics of blood flow within the lesion and surrounding normal tissue. Since both the lesion itself and adjacent normal tissue demonstrate characteristic findings in each circulatory phase, the study provides a large amount of data on the flow of blood and contrast material which facilitate both recognition and diiferentation of a lesion. Late studies following administration of a contrast agent allow an estimate of the passage of the contrast medium to the inter stitium, which is of diagnostic importance. Chapters dealing with specific clinical entities also contain useful information on the most appropriate means of contrast agent administration (bolus injection or infusion) as well as a discussion of indications for the procedure. Dynamic computed tomography represents a significant advance over conventional computed tomography in some situations, and this signifies a major contri bution to the diagnostic capabilities of the clinical radiologist. The authors are to be commended for the fact that they have clearly defined the limits of dynamic computed tomography. I hope that the first English language edition, following the appea rance of the German version in 1983, will be well received.
Download or read book Mathematics and Physics of Emerging Biomedical Imaging written by Committee on the Mathematics and Physics of Emerging Dynamic Biomedical Imaging and published by National Academies Press. This book was released on 1996-03-13 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: This cross-disciplinary book documents the key research challenges in the mathematical sciences and physics that could enable the economical development of novel biomedical imaging devices. It is hoped that the infusion of new insights from mathematical scientists and physicists will accelerate progress in imaging. Incorporating input from dozens of biomedical researchers who described what they perceived as key open problems of imaging that are amenable to attack by mathematical scientists and physicists, this book introduces the frontiers of biomedical imaging, especially the imaging of dynamic physiological functions, to the educated nonspecialist. Ten imaging modalities are covered, from the well-established (e.g., CAT scanning, MRI) to the more speculative (e.g., electrical and magnetic source imaging). For each modality, mathematics and physics research challenges are identified and a short list of suggested reading offered. Two additional chapters offer visions of the next generation of surgical and interventional techniques and of image processing. A final chapter provides an overview of mathematical issues that cut across the various modalities.

Download or read book Head Injuries written by R. A. Frowein and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 28th annual conference of the German Society for Neurosurgery was held in Cologne, West Germany, from the 18th to the 21st of September 1977. The conference dealt with problems concerning craniocerebral injuries and space-occupying processes in the posterior cranial fossa as well as general topics on clinical practice and research with special attention paid to the work of younger neurosurgeons. This volume is a presentation of the conference results. Within the scope of the general topics, special interest was directed toward the que stion of the current status of cytostatic treatment for brain tumors. In addition to experimental investigations, the results concerning cerebral tumors and medulloblas tomas are reported. Cerebellar tumors represent two further focal points: 1. From the diagnostic viewpoint, specific results from computerized tomography are discussed, especially with regard to the more extensive anatomic difficulties involved in the posterior cranial fossa. 2. With emphasis on cerebellar processes, the results of long-term measurements of intracranial pressure during the postoperative follow-up period are reported.
