Expanded in-house MRI analysis toolkit; work included developing models of neural atrophy for MRI analysis at Mayo clinic.
High costs, lack of speed, non-intuitive interfaces, and inefficient, fragmented display of patient information have hindered the adoption of the Electronic Health Record (EHR). Critical factors inhibiting adoption of the EMR include the time spent by the health care providers (HCP) in accessing and also documenting patient information during clinical encounters. We describe an emerging visual analytics system dedicated to clinical encounters in emergency room scenarios. It unifies all EMR information fragments into a single interactive visual framework, controlled by voice and touch, in which physicians can conduct diagnostic reasoning tasks in a direct data and information centric manner. We illustrate our system by ways of a typical clinical scenario and point out directions for future research and development.
The common neuro degenerative pathologies underlying dementia are Alzheimer’s disease (AD), Lewy body disease (LBD) and Frontotemporal lobar degeneration (FTLD). Aim of this project was to identify patterns of atrophy unique to each of these diseases using antemortem structural-MRI scans of pathologically-confirmed dementia cases and build an MRI-based differential diagnosis system. We created atrophy maps using structural-MRI and applying them for classification of new incoming patients is labeled Differential-STAND (Differential-diagnosis based on STructural Abnormality in NeuroDegeneration).
Over the last decade the discovery of fluorescent proteins has revolutionized in-vivo imaging in neuroscience. Fluorescent proteins combined with transgenic techniques have allowed researchers to quantify and analyze behavior of various complex cortical circuits across several organisms at Janelia. 2-photon excitation laser scanning microscopy (2PE) has especially aided this endeavor. 2PE has allowed for acquisition of high-resolution, high-sensitivity fluorescence microscopy image’s in intact neural tissue.
ScanImage (3.x, 4.x) is open source customizable software written for 2PE laser scanning microscopes to meet the agile needs of researchers at Janelia and elsewhere.
