Description
Abstract:
Many applications in CT imaging require imaging of time-varying data as well as an analysis of the motion fields between different configurations. In this talk, I will focus on joint 4D (space+time) geometry and motion analysis using new tomographic reconstruction methods. These methods are applicable in any scenario where either:
- a time-varying phenomenon is investigated with tomographic methods (X-ray, EM, etc.), and the time scale of the motion is comparable to the frame rate of projections in the imaging system,
or
- whenever the sample undergoes uncontrolled deformation during the scanning process (e.g. drift, heat expansion, or sample degradation).
I will illustrate the methods using examples from graphics as well as composite material science applications. I will also highlight the relationship of these methods to recent fluid imaging methods.
