Introduction Respiratory organ motion is a complicating factor in many treatments. Especially for dynamic dose delivery such as in tumor therapy, exact knowledge of organ motion and its influence on the dose distribution is crucial. Siebenthal et al [1] recently purposed a novel respiratory correlated MR imaging method that acquires a full 2D sagittal navigator image instead of the commonly use...

PURPOSE To develop a navigator technique enabling free-breathing acquisition to afford sufficient signal averaging for quantitative renal perfusion measurement using arterial spin labeling MRI. METHODS A novel two-dimensional (2D) navigator technique was implemented in concert with flow-sensitive alternating inversion recovery (FAIR) preparation and true fast imaging with steady precession (T...

PURPOSE To evaluate in healthy volunteers the usefulness of an abdominal compression belt in reducing acquisition time by stabilizing respiratory motion during whole-heart coronary magnetic resonance angiography (WHCMRA) using conventional navigator triggering. METHODS In 10 healthy volunteers, we performed free-breathing 3-dimensional segmented true fast imaging with steady-state precession ...

Magnetic resonance coronary angiography (MRCA) has been proven to be feasible for imaging of the proximal and medial portions of the three main coronary arteries. Free breathing techniques allow for high resolution imaging but prolong scan time. This could potentially be shortened by improving the efficiency, robustness and accuracy of the navigator gating algorithm. Aim of this study was to de...

OBJECTIVE To examine the feasibility of daily use of a continuous glucose monitor, the FreeStyle Navigator Continuous Glucose Monitoring System ("Navigator"), in children with type 1 diabetes (T1D). STUDY DESIGN After a masked Navigator was used for 4 to 7 days to establish a baseline level of glycemic control, 30 insulin pump users with T1D (average age 11.2 years) were asked to use the Navi...

Abstract: The paper presents a redundant architecture of a bi-dimensional strap-down inertial navigator in vertical plane. The redundance of the developed system is provided by its inertial measurement unit, containing inertial sensors arrays in a linear redundant configuration. The inertial sensors data in each of the three arrays (two for accelerometers and another one for gyros) are fused by...

The timing of a ship taking evasive maneuvers is crucial for the success collision avoidance, which affected by perceived risk navigator. Therefore, we propose alert system (CAS) based on navigator to trigger ship’s in timely manner avoid close-quarters situations. available maneuvering margins (AMM) with stability guarantees are selected as proxy reflect navigator; hence, proposed CAS referred...

We present study navigator, an algorithmically-generated aid for enhancing the experience of studying from electronic textbooks. The study navigator for a section of the book consists of helpful concept references for understanding this section. Each concept reference is a pair consisting of a concept phrase explained elsewhere and the link to the section in which it has been explained. We prop...

A significant amount of work has been done to better understand the barriers to knowledge flow and develop models of KM maturity; this was intended to help in assessing the progress of KM initiatives in the firm. However, to date there has been no comprehensive research that considers both these issues at the same time, and thus it is still necessary to explore the evolution of barriers to know...
