– This paper describes the major components and their interactions of a novel architecture called VITAL++ that combines the best features of the two seemingly disparate worlds, Peer-to-Peer (P2P) and NGN in particular IMS, which is then used to support multimedia applications and content distribution services. To this end, P2P is enhanced with advanced(More)
INTRODUCTION The primary aim of this study is to compare intensity modulated radiation therapy (IMRT) to volumetric modulated arc therapy (VMAT) for the radical treatment of prostate cancer using version 10.0 (v10.0) of Varian Medical Systems, RapidArc radiation oncology system. Particular focus was placed on plan quality and the implications on(More)
INTRODUCTION This article presents the results of a single-day census of radiation therapy (RT) treatment and technology use in Australia. The primary aim of the study was to ascertain patterns of RT practice and technology in use across Australia. These data were primarily collated to inform curriculum development of academic programs, thereby ensuring(More)
Funding Information No funding information provided. Abstract As radiation therapy transitions from intensity modulated radiation therapy (IMRT) to volumetric modulated arc therapy (VMAT) it is important to consider the quality assurance (QA) of VMAT plans in light of what has previously been learned and developed in IMRT QA. This technical note assesses if(More)
INTRODUCTION This study compared four different volumetric modulated arc therapy (VMAT) beam arrangements for the treatment of early-stage prostate cancer examining plan quality and the impact on a radiotherapy department's resources. METHODS Twenty prostate cases were retrospectively planned using four VMAT beam arrangements (1) a partial arc (PA), (2)(More)
IMS ARCS is an Industrial and Academic cooperative program conducting research in the area of IMS technology with a view to creating a body of intellectual property for the use of project partners , and serving as a case study on how to develop IMS end user and enabling services. The project employs the OpenIMS testbed from Fraun-hofer Fokus, as the basis(More)
Pervasive mobile communication is set to be greatly enhanced by the development and deployment of miniature mobile base stations, suitable for workplace or home. These base stations, known as Femtocells and Picocells, connect to traditional broadband connections, to offer greatly improved 3G communications to mobile handsets. Developing an architecture that(More)
