Abstract In this study, the feasibility of using electronic portal imaging device (EPID) as an analysing equipment for bolus material was evaluated in terms its dosimetric parameters. Seven superflab samples, 4 samples 0.5 cm (S1–S4) and 3 1 thickness (S5–S7), were analysed compared with tissue equivalent water phantom, which selected reference material. Gamma analysis method used to evaluate d...

conclusions the sophistication of electronic prescription and integration with ehr will become a reality, if all its stakeholders collaborate in developing fast and secure electronic prescription systems. it is plausible that the required infrastructure should be provided for implementation of the national integrated electronic prescription systems in countries without the system. given the bar...

Web portals are ubiquitous, but an operational portal containing sensitive electronic archival records has not existed in a public network due to security concerns; therefore, setting one up requires serious consideration of defensive security measures. The key topic of this paper is a security architecture for the protection of an experimental portal that provides its stakeholders with conveni...
