Presentations

  • External Advisory Board Presentation 2011. This was a progress update and plans for the future relating to SCRun software.
  • Mountain West Biomedical Conference 2010. This is a podium presentation about using polynomial Chaos-Stochastic Collocation to understand ECG sensitivity.
  • Computing in Cardiology 2010. Podium presentation in Belfast about the effects of conformal meshing on electrical simulations.
  • PhD Proposal 2010. This was my proposal to my committee which they accepted.
  • World Congress 2009 - Border Zone. This is the presentation about the border zone sensitivity and transition zone that I presented in Munich.
  • CinC 2009 - Volumetric WEB interpolation. I presented this at computers and cardiology on when to use WEB interpolation and when not to.
  • PHD Committee 2009 - Pre-Proposal. This was the first presentation I gave to my committee.
  • EAB_Pres - Subject Specific Modeling. I presented this to the CIBC external advisory board. It highlights the subject specific modeling pipeline used to create the ischemia models.

    Videos

  • Simulated Activation Wave. This was computed using CHASTE and visualized with SCIRun.
  • Interpolated transmural plunge electrodes. This shows how complex real activation waves can be.
  • The perfusion bed contrasted with Gd. This is an volume rendering of a canine heart with Gd injected into the LAD.
  • Isosurface of the heart. This surface was created using a marching cubes algorithm combined with mesh fairing. This shows that we can capture much of the detail of the heart structure, including trabeculation and papillary muscles.
  • Solved ischemia model. This shows the solved ischemia model using the perfusion bed as the ischemic region and a border zone of one element in width.
  • Rabbit leg electrodes. This was work done for Brad Isaacson to validate a bone growth study we was working on.
  • Subject Specific Pipeline - Cardiac. This was a video I made for a display at the SLC library. It shows the steps of creating the computational electrophysiological models. Please ignore the text, they made me put it on there and then they edited it down to where it doesn't make sense anymore.
  • The development of Ischemia. This shows the development of ischemia, taken at 40% of the ST segment, with a time step every 30 seconds and an increase in heart rate after every 4 recordings.
