Introduction The LGE method can visualize post-ablation scar in the LA, using increased spatial resolution (1-2). However, the inversion pulse required for LGE also nulls the liver signal at the time of data acquisition (optimal TI time), so that NAV-gating, used for respiratory compensation, becomes impossible. The NAV-restore (3), which reinverts the region of the liver immediately after the ...

In this study, we evaluated the performance of an Elekta linac in the delivery of gated radiotherapy. Delivery accuracy was examined with an emphasis on the impact of using short gating windows (low monitor unit beam-on segments) or long beam hold times. The performance was assessed using a 20cm by 20cm open field with the radiation delivered using a range of beam-on and beam-off time periods. ...

DEDICATION To my parents and friends v ACKNOWLEDGEMENTS I would like to thank my advisor Professor Wayne Burleson and Prof. Sandip Kundu for all their support and guidance throughout this work. Their valuable feedback helped me to focus on the topics of this research. I also would like to thank Prof. Joseph Bardin for serving on my committee and providing valuable suggestions during the course ...

We demonstrate real-time microscope image gating to an arbitrary position in the cycle of the beating heart of a zebrafish embryo. We show how this can be used for high-precision prospective gating of fluorescence image slices of the moving heart. We also present initial results demonstrating the application of this technique to 3-D structural imaging of the beating embryonic heart.

Creativity has previously been linked with atypical attention, but it is not clear what aspects of attention, or what types of creativity are associated. Here we investigated specific neural markers of a very early form of attention, namely sensory gating, indexed by the P50 ERP, and how it relates to two measures of creativity: divergent thinking and real-world creative achievement. Data from ...

reformatted images from non-gated and self-gated SPACE imaging. Note that images suffered from severe motion artifacts due to swallowing without self-gating motion compensation. Figure 2. (a) Correlation coefficients calculated between each projection and the reference profile; (b) Self-gating projection signals of the neck as a function of time; (c) Two projection signals acquired with and wit...
