Digital Options for Panoramic Radiology

Digital radiology and PACS.

Future hospital information systems should permit the systematic storage of all information generalized within the hospital, including medical diagnostic images. For such a system to be realized, implementation of a picture archiving and communication system (PACS) is needed. The development of computed radiography with an imaging plate (CR) has made it possible for digitalization of all kinds ...

Digital Radiology: an Opportunity for Quantitative Measurement

A digital detector provides numerical information at each pixel. This value may be difficult to be interpreted quantitatively. In this paper, the main factors to be considered during physical interpretation are reviewed: beam-hardening effect, scattering diffusion, type of detector. Some of them induce degradation on the digital radiograph while others modify the nature of available information...

Digital Certificates Resource Sharing Service Capability Evaluation

The certification resource is a very special class of information resources of the government, which has huge amount of information and frequency usages of government administrative activities. With the various administrative departments’ in-depth online approval, there is an urgent demand for certificates information sharing needs, especially in interdepartmental tasks. In this paper, governme...

Digital Signatures, Certificates and Electronic Commerce

Cryptography as practised for 3500 years before the mid-1970s used one secret, known by both the enciphering and deciphering parties. Anyone possessing that secret (called the key) was able to do either operation. In public key cryptography there are two different keys, one used to encipher data and the other used to decipher it. While one of these keys is kept private, the other is made public...
