Autor: Amanda Boczkowski, Sarah Strand, David A. P. Dunkerley, Jeffrey E. Snyder, Joel St-Aubin, Daniel E. Hyer, Sridhar Yaddanapudi, Blake R. Smith

Publikováno v: Journal of Applied Clinical Medical Physics

The Elekta Unity MR-linac utilizes daily magnetic resonance imaging (MRI) for online plan adaptation. In the Unity workflow, adapt to position (ATP) and adapt to shape (ATS) treatment planning options are available which represent a virtual shift or

The distribution of diatom species and their evolutionary histories are largely a result of the complex feedback mechanisms in their environment. Arctic lakes are particularly sensitive to climate changes, and the species within these environments re

Using ZDR Columns in Forecaster Conceptual Models and Warning Decision-Making

Autor: Terry J. Schuur, Charles M. Kuster, T. Todd Lindley, Jeffrey C. Snyder

Publikováno v: Weather and Forecasting. 35:2507-2522

Research has shown that dual-polarization (dual-pol) data currently available to National Weather Service forecasters could provide important information about changes in a storm’s structure and intensity. Despite these new data being used graduall

Statistical and Empirical Relationships between Tornado Intensity and Both Topography and Land Cover Using Rapid-Scan Radar Observations and a GIS

Autor: Jeffrey C. Snyder, Michael M. French, Howard B. Bluestein, Jana B. Houser, Nathaniel L. McGinnis, Kelly M. Butler

Publikováno v: Monthly Weather Review. 148:4313-4338

This study presents an investigation into relationships among topographic elevation, surface land cover, and tornado intensity using rapid scan, mobile Doppler radar observations of four tornadoes from the U.S. Central Plains. High spatiotemporal res

An Analysis of an Ostensible Anticyclonic Tornado from 9 May 2016 Using High-Resolution, Rapid-Scan Radar Data

Autor: Dylan W. Reif, Charles M. Kuster, Howard B. Bluestein, Zachary B. Wienhoff, Jeffrey C. Snyder

Publikováno v: Weather and Forecasting. 35:1685-1712

Tornadic supercells moved across parts of Oklahoma on the afternoon and evening of 9 May 2016. One such supercell, while producing a long-lived tornado, was observed by nearby WSR-88D radars to contain a strong anticyclonic velocity couplet on the lo

Commissioning of a 1.5T Elekta Unity MR‐linac: A single institution experience

Autor: Sridhar Yaddanapudi, Amanda Boczkowski, Daniel E. Hyer, Jeffrey E. Snyder, Joel St-Aubin, Stephen A. Graves, David Dunkerley

Publikováno v: Journal of Applied Clinical Medical Physics

MR image‐guided radiotherapy has the potential to improve patient care, but integration of an MRI scanner with a linear accelerator adds complexity to the commissioning process. This work describes a single institution experience of commissioning a

Publikováno v: Physics in medicine and biology. 67(5)

Objective. Extended treatment session times are an operational limitation in magnetic resonance imaging guided adaptive radiotherapy (MRIgRT). In this study a novel leaf sequencing algorithm called optimal fluence levels (OFL) and an optimization alg
