Over the past 100 years, both diagnostic radiology and radiation therapy have grown from infancy to maturity. Accompanying this growth, the discipline of medical physics has evolved and advanced accordingly. New diagnostic and therapeutic procedures continue to be developed, for example, multidetector computed tomography, multileaf collimation, magnetic resonance imaging, dual-source computed t...

introduction: nowadays, without utilization of information technology, it is impossible to have effective access to required information. inappropriate use of new technology for professional knowledge transmission leads to inadequacy of technology as well as cost wasting. therefore, it is necessary to enhance general understandings about information technology (it) abilities and also end-user n...

introduction: disaster occurs almost daily in the world and increases the issue of it because of high volume of population, industrialization and acts of terrorism, my country is one of the most unexpected event areas of the world. health care systems encounter special challenges in disaster management, that they include triage and treatment a large number victims and also victims' information ...

This paper describes a national eHealth platform concept with a multi-level privacy protection in order to improve the security and privacy of medical information on their storage locations as well as during the exchanging/sharing processes. The key idea is to classify and split-up data into different servers. A Trusted Third Party server manages personal identifying data together with the rela...

Computed radiography (CR) uses storage phosphor imaging plates for digital imaging. Absorbed X-ray energy is stored in crystal defects. In read-out the energy is set free as blue photons upon optical stimulation. In the 35 years of CR history, several storage phosphor families were investigated and developed. An explanation is given as to why some materials made it to the commercial stage, whil...

Healthcare and crisis management are pervaded by the usage of Information Systems (IS). Virtually all IS rely on data storage. Despite the document-oriented nature of medical datasets, the prevailing kind of database used are relational (RDBMS) ones. In order to find a more adequate solution in a development project for a patientregistry, we evaluated a document-based database incorporated into...

Advance medical imaging requires storage of large quantities of digitized clinical data. Due to the bandwidth and storage limitations, medical images must be compressed before transmission and storage. Diagnosis is effective only when compression techniques preserve all the relevant and important image information needed. There are basically two types of image compression: lossless and lossy. L...
