Book Synopsis Three-dimensional Reconstruction in Nuclear Medicine by Iterative Least-squares and Fourier Transform Techniques by : Thomas Francis Budinger
Download or read book Three-dimensional Reconstruction in Nuclear Medicine by Iterative Least-squares and Fourier Transform Techniques written by Thomas Francis Budinger and published by . This book was released on 1974 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quantitative three-dimensional distribution of isotopes in patients is determined by digital reconstruction of data from many views taken by rotating the subject at 10[degree] intervals before the gamma camera. The superiority of these techniques over conventional tomography is demonstrated by comparisons between reconstruction algorithms such as back-projection, simultaneous iterative reconstruction, iterative least-squares, and back-projection of filtered projection. The filtered back-projection technique (convolution method) is superior in speed; however, for quantitative results that take into account both noise and attenuation, the iterative least-squares method gives the best approximation to the real source distributions. Resolution is 1.25 cm for detection of holes in 20-cm-diameter objects. Mathematical basis and FORTRAN listings applicable to transmission and emission imaging are given, as well as phantom patient studies.

Book Synopsis Three-Dimensional Image Reconstruction in Radiology and Nuclear Medicine by : Pierre Grangeat
Download or read book Three-Dimensional Image Reconstruction in Radiology and Nuclear Medicine written by Pierre Grangeat and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains a selection of communications presented at the Third International Meeting on Fully Three-Dimensional Image Reconstruction in Radiology and Nuclear Medicine, held 4-6 July 1995 at Domaine d' Aix-Marlioz, Aix-Ies-Bains, France. This nice resort provided an inspiring environment to hold discussions and presentations on new and developing issues. Roentgen discovered X-ray radiation in 1895 and Becquerel found natural radioactivity in 1896 : a hundred years later, this conference was focused on the applications of such radiations to explore the human body. If the physics is now fully understood, 3D imaging techniques based on ionising radiations are still progressing. These techniques include 3D Radiology, 3D X-ray Computed Tomography (3D-CT), Single Photon Emission Computed Tomography (SPECT), Positron Emission Tomography (PET). Radiology is dedicated to morphological imaging, using transmitted radiations from an external X-ray source, and nuclear medicine to functional imaging, using radiations emitted from an internal radioactive tracer. In both cases, new 3D tomographic systems will tend to use 2D detectors in order to improve the radiation detection efficiency. Taking a set of 2D acquisitions around the patient, 3D acquisitions are obtained. Then, fully 3D image reconstruction algorithms are required to recover the 3D image of the body from these projection measurements.
Book Synopsis Computers and Mathematical Models in Medicine by : D. Cardus
Download or read book Computers and Mathematical Models in Medicine written by D. Cardus and published by Springer Science & Business Media. This book was released on 2013-03-08 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: The papers gathered in this volume were presented at the medical sessions of the First Conference on Mathematics at the Service of Man held in Barcelona, Spain, July 11-16, 1977. Papers presented at the medical sessions were more numerous than those pre sented in any other single area of specialization covered in the conference. Because pf this, the Publications Committee resolved that papers presented at medical sessions be published separately from the proceedings of the conference. The proceedings of the conference have been published by the Esco1a Tecnica Superior d'Arquitectura de 1a Universitat Po1itecnica of Barcelona. The papers contained in this volume were selected on the basis of current interest and willingness of the authors to publish. They are organized not accord ing to the sequence in which they were presented at the conference, but, to the extent that this was possible, in topic areas. As its name indicates, the principal purpose of the conference was to under score the fact that mathematics is a science whose applications are relevant to many aspects of human activity. In the opinion of the editors of this volume, the conference met its objective with success, both in terms of the broad variety of topics covered as well as by the number of nations that were represented at the conference in spite of the special circumstances prevailing in Spain at that time.
Book Synopsis Diagnostic Imaging in Medicine by : Richard C. Reba
Download or read book Diagnostic Imaging in Medicine written by Richard C. Reba and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 723 pages. Available in PDF, EPUB and Kindle. Book excerpt: An Advanced Study Institute on Ultrasonics in Medical Diagnosis was held in Milan, Italy, from 10 to 15 June 1974. This ASI was of a short five-day duration and limited to cardiac diagnosis by ultra sound only. Since that time, the field of diagnostic imaging in medicine has literally exploded with new and improved means of medical diagnosis such as computed tomography, microwaves, nuclear magnetic resonance and other sophisticated techniques. These developments have enabled medical practitioners to make diagnoses with a minimum of danger to the patient, and a maximum of accuracy never before possible, and represent a multi-quantum advance over the early state-of-the-art presented at the 1974 ASI. Since then, several meetings have taken place on these individual topics to bring together experts who presented their latest research results, but none have discussed the entire field of diagnostic imaging in medicine in one meeting nor have they had the teaching character of an Advanced Study Institute. The art and science of medicine have been altered repeatedly during the eight year interval since the last ASI. Today's clinician must be part technologist and must be enough of an investigator to understand and appreciate the scientific method. The current complex advances in instrumentation and pharmacology have had a marked effect on how medicine is practiced. There was, therefore, an urgent need to bring the entire field of imaging in medicine to one teaching podium where the many advances of the last six or seven years could be reviewed.

Book Synopsis Digital Processing of Biomedical Images by : K. Preston
Download or read book Digital Processing of Biomedical Images written by K. Preston and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: Until recently digital processing of biomedical images was conducted solely in the research laboratories of the universities and industry. However, with the advent of computerized tomography in 1972 and the computerized white blood cell differential count in 1974, enormous changes have suddenly occurred. Digital image pro cessing in biomedicine has now become the most active sector in the digital image processing field. Processing rates have reached the level of one trillion picture elements per year in the United States alone and are expected to be ten trillion per year in 1980. This enormous volume of activity has stimulated further re search in biomedical image processing in the last two years with the result that important inroads have been made in applications in radiology, oncology, and ophthalmology. Although much significant work in this field is taking place in Europe, it is in the United States and Japan that the level of activity is highest.
Book Synopsis Medical Informatics Europe 78 by : J. Anderson
Download or read book Medical Informatics Europe 78 written by J. Anderson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 822 pages. Available in PDF, EPUB and Kindle. Book excerpt: These proceedings reflect the major scientific contribution by the First International Congress of the European Federation for Medical Informatics. The European Federation for Medical Informatics is a co-operative venture between the National Informatics Societies of Europe. It is sponsoring this first inter national meeting organised by the Medical Specialist Groups of the British Society under the guidance of a European Scientific Programme Committee. The challenge of medical informatics has been well taken and the scientific papers by its members cover a wide range of topics dealing with medical records, laboratory investigation, indexing and administrative systems, nursing records, planning and administration modelling, data bases, text processing, transferability, user education, privacy, etc. Not published in this volume are presentations by industry about hardware and software. Also at the meeting there will-be teaching sessions for doctors, nurses, scientists and administrators who are just entering this field which are also not published. Medical informatics has established itself as an important area of medical activity and its growing application, as this conference illustrates, suggests a very rich potential for the future. Aids to medical decision making and modelling are newer areas of activity, where significant progress has been made. Sociological changes have taken place to meet this challenge and developments in the issues of privacy and confidentiality are important, as also are user education, and the teaching of medical informatics to medical students and to doctors.
Book Synopsis Questions of Uniqueness and Resolution in Reconstruction from Projections by : M. B. Katz
Download or read book Questions of Uniqueness and Resolution in Reconstruction from Projections written by M. B. Katz and published by Springer Science & Business Media. This book was released on 2013-03-13 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reconstruction from projections has revolutionized radiology and has now become one of the most important tools of medical diagnosis The E. M. I. Scanner is one example. In this text, some fundamental theoretical and practical questions are resolved. Despite recent research activity in the area, the crucial subject of the uniqueness of the reconstruction and the effect of noise in the data posed some unsettled fundamental questions. In particular, Kennan Smith proved that if we describe an object by a C^inf_o function, i.e., infinitely differentiable with compact support, then there are other objects with the same shape, i.e., support, which can differ almost arbitrarily and still have the same projections in finitely many directions. On the other hand, he proved that objects in finite dimensional function spaces are uniquely determined by a single projection for almost all angles, i.e., except on a set of measure zero. Along these lines, Herman and Rowland in "Three Methods for reconstructing objects from x-rays: a comparative study" (1973) showed that reconstructions obtained from the commonly used algorithms can grossly misrepresent the object and that the algorithm which produced the best reconstruction when using noiseless data gave unsatisfactory results with noisy data. Equally important are reports in Science, and personal communications by radiologists indicating that in medical practice failure rates of reconstruction vary from four to twenty percent. within this work, the mathematical dilemma posed by Kennan Smith's result is discussed and clarified.
