8 a.m. – 4 p.m.

Vancouver West Convention Center

The increased accessibility of 3D imaging to researchers and clinicians has improved visualization of complex structures. The scanning instruments are sold with proprietary software that can be used for qualitative display of differences. To determine empirically how much the face or jaws have changed in 3D requires the use of other software packages. However, the learning curve is steep and the features of the software can be varied. The workshop is targeted at scientists and clinicians who want to use quantitative approaches with 3D data and learn more from experts in the field. The speakers have been chosen because they are pioneers in using 3D imaging and analysis (microCT, CBCT, 3D photogrammetry), to study morphology changes in animal models and patients. They will each give background into their research question and the approaches ranging from landmark-based geometric morphometrics, semi-landmarks as well as newer, dense surface mapping methods which provide information on global and local shape changes. The hands-on sections will be led by Marat Maga, Lucia Cevidanes, Scott Lozanoff as well as trainees in the Richman and Vora laboratories.

Learning Objective 1
To demonstrate an understanding of free software and how it complements proprietary software for image rendering, landmarking, segmentation and basic quantitative analysis.
Learning Objective 2
To gain experience in experimental design and implementation using hands on manipulation of 3D datasets.
Learning Objective 3
To understand the scope of different shape analysis methods (geometric morphometrics, deformation based morphology, asymmetry analysis etc)
