ToScA North America
Chair: Dr Farah Ahmed (NHM, UK)
Co-chair: Dr Jessie Maisano (University of Texas at Austin)
For the first time, a ToScA symposium will take place in Austin, Texas, bringing together the North American tomography community. The meeting will be hosted by the University of Texas at Austin High-Resolution X-ray CT Facility (UTCT) and the Jackson School of Geosciences.
Presentations will address hard and soft tissue imaging, understanding materials in 3D, recent advances in hardware and software, and a broad range of applications in tomography.
As in the UK, this symposium will include pre-conference hands-on software workshops, keynote speakers, student talks and poster presentations, and an image competition. The meeting provides an opportunity for open discussions, networking with researchers and commercial industry representatives, and a platform to engage in collaborations.
Registration has now closed.

VGSTUDIO MAX 3.0 – Workshop
This workshop will introduce you to CT data analysis and visualization using VGSTUDIO MAX. Volume Graphics will present typical workflows which are of special interest for the scientific community for the fast and precise analysis of voxel data: quantitative analysis options, segmentation, and advanced visualization techniques. VGSTUDIO MAX is the ideal tool for getting the most information possible from your data sets, whether acquired by laboratory X-ray CT, a synchrotron, with neutrons, or with another source. Use this special opportunity to speak personally with Volume Graphics experts!
Duration: 2:30 h
Avizo introductory workshop including porosity analysis
Participants will be offered an introduction to data visualization, image processing & segmentation and the chance to try a new series of features for extending analyses performed on porous materials.
Avizo software currently offers advanced quantification features for computing volumes on each pore individually, including surfaces, shape characteristics, orientations, distance to the surface of the object, and distance to the nearest neighbor. The software’s new features allow the study of the porous network as a whole and simplify the representation of the pores and the pore throats in the network. It enables filtering of the pores based on various criteria, along with the computation of measures such as permeability or tortuosity.
During the workshop, participants will use Avizo to perform data visualization, image processing, segmentation and a full analysis of a porous material.
• General introduction to Avizo software
• What's new in Avizo 9.4
• Hands-on session
- Introduction to workspace, modules & data visualization
- Image processing & segmentation
- Introduction to pore network modeling and new features
Duration: 2:30 h

Dr Jessie Maisano
ToScA North America Chair
University of Texas
Dr. Jessie Maisano is a research scientist at the University of Texas High-Resolution X-ray CT Facility (UTCT) in Austin. She received her BA in geology at Kent State University in 1994 and her PhD in vertebrate paleontology at Yale University in 2000. She then moved to the University of Texas as a postdoc on the then-nascent Digital Library of Morphology (DigiMorph.org). Jessie held a subsequent postdoctoral position on the Deep Scaly project (Assembling the Tree of Life) before being hired as full-time staff by UTCT, where she is now facility manager. She is also the primary operator of UTCT’s Zeiss MicroXCT-400 and caretaker of DigiMorph.org. Jessie’s main research interests lie in squamate (lizards, snakes, amphisbaenians) osteology as revealed by CT, especially cranial anatomy and ‘extraskeletal’ systems such as osteoderms. However, her collaborations via UTCT have resulted in publications on topics as diverse as carbon sequestration, diamond formation, and Ediacaran fauna.
Dr Farah Ahmed
University of Texas
Steve Gatesy is a paleontologist and morphologist interested in the evolution of vertebrate locomotion. By combining biomechanical analyses of living animals with fossil bones and footprints, he explores functional transitions in dinosaur bipedality and the origin of bird flight. For the last 20 years he has embraced animation software to study animal motion, culminating in X-ray Reconstruction of Moving Morphology (XROMM). Co-developed with colleagues at Brown University, XROMM merges CT-based bone models with pairs of X-ray videos to visualize and measure 3-D skeletal movement with unprecedented accuracy and precision. XROMM data offer an anatomically-detailed look inside diverse taxa—a dynamic lens through which to view skeletal form.
Lawrence M. Witmer is Professor of Anatomy at the Ohio University Heritage College of Osteopathic Medicine in Athens, Ohio, as well as the Chang Professor of Paleontology and an OU Presidential Research Scholar. He received degrees from Cornell University, the University of Kansas, and the Johns Hopkins University School of Medicine. Witmer and his team are known for “fleshing out” dinosaurs and their kin with the soft tissues not normally preserved in fossils. Witmer combines classical anatomical approaches (such as dissection) with high-tech CT scanning and CGI to restore key soft-tissue systems such as the brain, eye, nose, ears, muscles, and blood vessels to shed light on dinosaur behavior and physiology. Witmer has received numerous grants from the National Science Foundation, and has published articles in Science, Nature, and other technical journals. He has appeared on dozens of internationally televised documentaries, as well as commenting on CNN, NPR, and other national media. WitmerLab has a significant presence on social media.
