A few presentations from over the last year, including conferences and classes.

In the Spotlight:
Modeling Task-Based Imaging Performance in Statistical Image Reconstruction
G. Gang et al.

Novel 3D image reconstruction methods, such as statistical model-based iterative reconstruction, pose challenges to modeling and measuring imaging performance due to intrinsic non-linearities and non-stationarities in noise and spatial resolution that defy straightforward application of conventional image quality models. Recent work by Grace Gang extends task-based image quality analysis to describe not only the non-stationarities intrinsic to filtered backprojection (FBP) but also the task-based performance of quadratic penalized likelihood (PL) image reconstruction.

(See Gang et al. AAPM 2013, below)
