Software Tools for Image Based Modeling, Simulation, and Visualization

August 31st, 2011
at EMBS 2011
Boston, MA


Summary

The goal of this tutorial is to introduce participants to a suite of software tools for image-based modeling, simulation, and visualization developed by the NIH/NCRR Center for Integrative Biomedical Computing (CIBC). This portable and flexible collection of interactive tools was designed in particular to support the development of subject specific, image based geometric models for simulation of bioelectric fields. The tools, individually or as a suite, have much broader utility and have supported research and clinical projects all over the world.

The tools in the suite include:

  • Seg3D, for general purpose user-guided image segmentation;
  • ImageVis3D, for visualization of large scale data;
  • map3d, for visualization of surface based maps from multichannel time signals;
  • BioMesh3D, a set of utilities for creating surface and volume meshes from segmented image data;
  • SCIRun, a comprehensive problem solving environment that integrates many of the capabilities of an entire image based modeling pipeline.

The tutorial will be a mix of didactic presentations on the components of image based modeling, simulation, and visualization; hands on practice with the software; and cases studies of real world applications. We will provide participants with the software and test data sets and encourage participants to bring their laptop computers, and, if relevant, their own data. CIBC members and developers will be on hand to help participants learn the programs, port their data, and generate useful results. We especially encourage participation by students, post docs, and technical users and software developers. Binary distribution installers (recommended) will be available for Apple OS X and Windows operating systems.

Extra Minisymposium at EMBS

Imaging and Computation in Clinical Electrocardiology

Thursday, September 1st from 5:15pm - 6:45pm
Marriott 3rd floor, Berkeley
Open to all registered conference attendees
Organizers: Robert MacLeod, PhD - University of Utah
Dana Brooks, PhD - Northeastern University
Speakers: Ravi Ranjan, MD PhD - University of Utah
Petr Stovicek, MD PhD - Charles University Hospital
John Triedman, MD - Harvard Medical School

Investigators have been conducting research on the use of imaging and computation in electrocardiology for many years. However until fairly recently the impact of advances in this area on clinical practice has been minimal except in a few specialized areas. In contrast, recent research progress, combined with improvements in imaging and computational technology itself, have begun to result in many exciting possibilities for clinical application of research results. In particular the combination of imaging and computation is enabling dramatic expansion of the concept of "personalized medicine" beyond the world of genomics by enabling patient-specific modeling and simulation. This minisymposium will focus on both progress and challenges in three distinct clinical applications of imaging and computational research, from the points of view of three presenters who are each clinicians who are active in both clinical practice and research.

Presenter bios:

Ravi Ranjan, MD, PhD, is Assistant Professor of Medicine, University of Utah. He is a clinical cardiac electrophysiologist with a keen interest in understanding arrhythmia mechanisms and developing new therapies. His PhD research was on understanding ion channel physiology and cardiac excitation and propagation using experimental studies and mathematical modeling. He continued work on ion channel structure and function during his medical studies. Recent work focused on the importance of gaps in ablation lesion sets as a cause of poor outcome of ablation procedures. Currently, he is working on better understanding of atrial fibrillation in an animal model using MRI.

Petr Stovicek, MD, PhD, has been engaged in ECG research since 1986, He has worked on simultaneous cardiac polygraphy and body surface potential mapping and has published on pathologies, including comparative case-control studies and invasive measurements in patient with coronary artery disease and arrhythmias. After training at Dalhousie University and QEII Health Sciences Centre in Halifax, Canada, he opened a cardiac electrophysiology laboratory for Charles University Hospital (Department of Medicine II) in Prague, Czech Republic, where he introduced routine catheter ablations of arrhythmias. More recently he has been advancing clinical use of biophysical computer modellng and imaging (ECG lead transformation, inverse electrocardiography).

John Triedman, MD, is Professor of Pediatrics at Harvard Medical School and a senior cardiologist at Children's Hospital Boston, specializing in interventional cardiac electrophysiology. His research topics have included three-dimensional arrhythmia mapping, the pathogenesis of arrhythmias in congenital heart disease, the application of nonfluoroscopic navigation to catheter ablation, and modeling of defibrillating electrical fields in the human thorax.
