Abstract Scope |
The collection of high resolution 3D serial sectioned data sets has become increasingly important for investigation of material structures and properties. However, despite improvements in imaging technology, collecting high resolution information over statistically significant volumes requires significant experimental and computational resources. Often this results in a tradeoff between imaging resolution and sample volume size. Methods for examining the propagation of epistemic resolution error can provide valuable information for addressing this problem. By simulating the data collection process at progressively coarser resolutions on a small high resolution volume the propagation of epistemic resolution error can be quantified and predicted. Using these predictions, correction methods can be formulated and applied to lower resolution data sets to reduce error. This results in statistical properties from the low resolution data set which are significantly closer to those from the high resolution data set, ultimately leading to more accurate prediction of material properties. |
