Quality of life assessments in the evaluation of magnetic resonance imaging

Abstract: Health technology assessments incorporating measurement of quality of life are becoming increasingly common. In the evaluation of magnetic resonance imaging (MRI), the most widely used quality of life instrument has been the Rosser classification. The theoretical basis for incorporating such a measure in the evaluation of imaging technology is considered and several studies using this instrument are reviewed. Despite the obvious technical advances of MRI and its influence on clinical management, it has proved difficult to demonstrate that the use of this expensive new imaging technique contributes to improvement in health-related quality of life. Some reasons why the expected improvement has not been demonstrated are discussed, as are the quality of life instruments which may be appropriate in this setting.

High imaging technology and health care expenditures

Abstract: Health care expenditures constitute a large part of the gross domestic product of the industrialized world and are growing at an alarming rate in some countries, particularly in the United States. Although the expenditures of radiology represented only 3.5% of the total health-care bill in the United States in 1990, the high price of certain high-technology instruments, such as magnetic resonance imagers, attracts attention. Yet, high imaging technology properly used reduces the cost of health care as can be seen from many examples. High imaging technology is non-invasive and often replaces procedures that would require hospitalization. Ethical considerations, such as large expenditures during the last year of life and some inappropriate uses, presently counterbalance the savings that the use of high technology could otherwise offer. By controlling its proper uses, high imaging technology can be a very useful tool.

Imaging techniques and computers.

Abstract: Imaging technology has been the pacesetter of stereotactic technique since its introduction in clinical practice. Quite recently, the extraordinary quality of diagnostic neuroimages and the growing av

Imaging the Archives: Now Is the Time

Abstract: Archivists or librarians who convert their holdings to electronic format can, by using imaging technology, secure the safety of the original documents while creating substantially greater opportunities for using the information contained therein. A brief introduction to document imaging technology, along with an explanation of how it works, will be followed by an identification of six advantages of imaging technology for archival centers or for libraries containing important archives. The authors will also respond to eight common objections. Data security issues will be addressed in the context of improved services.

Louisiana State University Libraries' Electronic Imaging Laboratory.

Abstract: The authors provide a description of using imaging for preservation purposes. They make the case that imaging technology can exist with microfilming and can provide improved access to rare materials

Electronic Imaging Systems: Design, Applications, and Management

Abstract: Covering all aspects of electronic imaging, this reference shows both novices and experienced users how to increase productivity, reduce costs and increase job satisfaction implementing imaging technology. The text provides guidelines for applying electronic imaging systems as well as case studies taken from numerous types of organizations in both service and manufacturing organizations, local and national governments and educational institutions. The book also contains practical information on future trends in the technology, numerous tutorials/professional tips and contact information for vendors and prototype forms.

[Application of computer-assisted 3D imaging simulation for surgery].

Abstract: This article describes trends in application of various imaging technology in surgical planning, navigation, and computer aided surgery. Imaging information is essential factor for simulation in medicine. It includes three dimensional (3D) image reconstruction, neuro-surgical navigation, creating substantial model based on 3D imaging data and etc. These developments depend mostly on 3D imaging technique, which is much contributed by recent computer technology. 3D imaging can offer new intuitive information to physician and surgeon, and this method is suitable for mechanical control. By utilizing simulated results, we can obtain more precise surgical orientation, estimation, and operation. For more advancement, automatic and high speed recognition of medical imaging is being developed.

Imaging technology for robot maintenance and calibration

Abstract: Mature robots in the manufacturing industry, i.e. those which have been in operation for 10 to 15 years, start to show wear-out characteristics as the lives of individual components are exceeded. Studies in the automotive industry, for example, where robots have been used for mass production for over 15 years, show that robots fail from a vast range of component failure modes, including mechanical drive faults, electronic failures in drive and control, and control parametric failures. In automated plants, for example, the robots may account for 20% of lost production time and cost £ millions per year in lost production.. In the future, the construction industry will doubtless adopt more and more automation and robotic solutions for its processes, and will thus face similar problems. This is particularly so as the construction site presents a far more adverse environment for automation and robotics than generally found in the manufacturing industry.
