Experimental validation of Fastcat kV and MV cone beam CT (CBCT) simulator
Jericho O'Connell, Clayton Lindsay, Magdalena Bazalova-Carter
Purpose: To experimentally validate the Fastcat cone beam CT (CBCT) simulator against kV and MV CBCT images acquired with a Varian Truebeam linac. Methods: kV and MV CBCT images of…
FastCAT: Fast Cone Beam CT (CBCT) Simulation
Jericho O'Connell, Magdalena Bazalova-Carter
The fastCAT application uses pre-calculated Monte Carlo (MC) CBCT phantom-specific scatter and detector response functions to reduce simulation time for megavoltage (MV) and kilovo…
Unsupervised Learning Methods in X-ray Spectral Imaging Material Segmentation
Jericho O'Connell, Kevin Murphy, Spencer Robinson +2
In this work, we have investigated a number of unsupervised learning methods for material segmentation in projection x-ray imaging with a spectral detector. A phantom containing tw…
Cyberhubs: Virtual Research Environments for Astronomy
Falk Herwig, Robert Andrassy, Nic Annau +9
Collaborations in astronomy and astrophysics are faced with numerous cyber infrastructure challenges, such as large data sets, the need to combine heterogeneous data sets, and the…
