In recent year, Deformable Image Registration (DIR) has become commercially available in the field of radiotherapy. DIR is an exciting and interesting technology for multi-modality image fusion, anatomic image segmentation, Four-dimensional (4D) dose accumulation and lung functional (ventilation) imaging. Furthermore, DIR is playing an important role in modern radiotherapy included Image-Guided...

In [1], [2] the authors introduced the concept of Differentiated Reliability (DiR) applied to dedicated path protection (DPP) switching in Wavelength Division Multiplexing (WDM) rings. By means of the DiR concept, a network can be designed to provide multiple degrees of reliability and efficiently satisfy the user-specific requirements, yet minimizing the network total cost. This paper extends ...

PURPOSE To determine whether a spin-echo-based sequence, which are inherently insensitive to magnetic field inhomogeneity, can be used for brain cortical thickness measurement studies. MATERIALS AND METHODS By using a double inversion recovery (DIR) spin-echo-based sequence, cortical thickness estimates were performed from data acquired from seven healthy volunteers. The cortical thickness wa...

Charged-particle spectra associated with direct photon (γ dir) and π 0 are measured in p+p and Au+Au collisions at center-of-mass energy √ s N N = 200 GeV with the STAR detector at RHIC. A shower-shape analysis is used to partially discriminate between γ dir and π 0. Assuming no associated charged particles in the γ dir direction (near side) and small contribution from fragmentation photons (γ ...

Distributed Information Retrieval (DIR) is a generic area of research that brings together techniques, such as resource selection and results aggregation, dealing with data that, for organizational or technical reasons, cannot be managed centrally. Existing and potential applications of DIR methods vary from blog retrieval to aggregated search and from multimedia and multilingual retrieval to d...

BACKGROUND A discordant immune response (DIR) is a failure to satisfactorily increase CD4 counts on ART despite successful virological control. Literature on the clinical effects of DIR has not been systematically evaluated. We aimed to summarise the risk of mortality, AIDS and serious non-AIDS events associated with DIR with a systematic review. METHODS The protocol is registered with the Ce...
