Introduction The use of two inversion delays with two inversion pulses allows signals with being suppressed two different tissues simultaneously, and is termed a double inversion recovery (DIR) sequence(1,2,3). Non-invasive characterizations of an effusion on the basis of imaging may obviate the need for joint aspirations with its associated patient morbidity. A fluid of the knee may consist of...

InSAR signal delays due to the varying atmospheric refractivity are a potential data source to improve weather models [1]. Especially with the launch of the new Sentinel-1 satellites, which increases data coverage, latency and accessibility, it may become possible to operationalize the assimilation of differential integrated refractivity (DIR) values in numerical weather models. Although studie...

Path Multiplexing (PM) and Link Multiplexing (LM) [3, 5] are two approaches for establishing connections (or lightpaths) in optical networks. This paper describes distributed control protocols for establishing lightpaths in WDM networks using LM and PM. We propose and evaluate the performance of two classes of protocols, namely Source Initiated Reservation (SIR) and Destination Initiated Reserv...

Introduction Most gray matter volumetric studies use T1-weighted imaging such as MP-RAGE because it provides good contrast between white matter and cortex. However, due to susceptibility artifact coming from the air-tissue interface (Fig. 1), a reliable and accurate measurement is difficult in the regions near the air-bone interface for T1-wieghted schemes. One way to alleviate this problem is ...

PURPOSE A novel pulmonary ventilation imaging technique based on four-dimensional (4D) CT has advantages over existing techniques and could be used for functional avoidance in radiotherapy. There are various deformable image registration (DIR) algorithms and two classes of ventilation metric that can be used for 4D-CT ventilation imaging, each yielding different images. The purpose of this stud...
