Relating brain anatomy and cognitive ability using a multivariate multimodal framework

eigenanatomy_ftd

Linking structural neuroimaging data from multiple modalities to cognitive performance is an important challenge for cognitive neuroscience. In this study we examined the relationship between verbal fluency performance and neuroanatomy in 54 patients with frontotemporal degeneration (FTD) and 15 age-matched … Continue reading

Interactive Medical Image Registration

Interactive image registration is required by some medical applications since automatic image registration is often slow and sometimes error-prone. We consider interactive registration methods that incorporate user-specified local transforms around control handles. The deformation between handles is interpolated by some … Continue reading

Regional Thickness Measurement of Extra-hippocampal Medial Temporal Lobe Structures

Extra-hippocampal medial temporal lobe (ehMTL) structures, which consists of entorhinal (ERC) and perirhinal (PRC) cortices, receives increasing attention because they are amongst the earliest sites affected by Alzheimer`s Disease (AD) pathology and due to their important and complex role in episodic … Continue reading

Sparse Dimensionality Reduction for Medical Imaging

The complex and high-dimensional nature of medical images makes them difficult to incorporate into traditional linear model-based statistical analysis.  One way of simplifying analysis of medical images is to use a dimensionality reduction technique.  We designed a dimensionality reduction technique … Continue reading
