Visible Embryo Project Overview • Deploy a system of visualization/ collaboration workstations using high performance networking • Digitize embryo data from the Carnegie Collection • the basis for collaboration experiments. • Demonstrate the system in three medical collaborations: • annotation and modeling • embryology education • clinical management planning • The NGI digital library project is supported by NIH/NLM. • We are in our third year, emphasizing the medical applications -- Objective: 3 or more sites collaborating
Visible Embryo Project Participants • GMU - overall direction, collaboration technology • Eolas - technical coordination, software • AFIP/NMHM - data acquisition • SDSC - data repository and rendering • LLNL - network facilitation • OHSU, UIC, JHU - medical demonstrations

Top level Data Flow to build digital library • Scan tiles @ 20X. • Combine into sections. • Annotate structures within sections. • Align sections. • Collaborate using visualization software. • e.g. Build 3D and “4D” models. • Capture all notes, etc. into archive during library use. Data capture station
Macaw flatbed scanners low power 20X 20X Origin 200 and RAID array local archiving NLM SDSC Data Capture and Storage Resource Broker (SRB) archiving • Imagewhere?TM software runs as a client on individual 20x capture stations. • At completion watchdogs: • detect and archive (index) all images. • move from local drive to RAID array. • use “marked up” 2X section locator images on slides and XML document to verify the files. • SRB Ingestion • SRB Ingestion scripts direct files to SDSC creating all appropriate directories. • After verification, files on capture RAID are erased. N.B. ingestion rates to SDSC approx. 4.8 MB/s

Create archives of tagged image data for visualization: • every voxel can be associated with many labels. • e.g. the organ system to which it belongs, the structure and tissue types represented, etc. • Applications: • Anatomic site mapping of gene expression • Analysis of embryonic cardiac hemodynamics • Integration of 3D graphics with symbolic knowledge for education, diagnosis, and treatment. Project Medical Applications
Initial review of serial images • Initial review of serial images • Variation of magnification • Registration • Segmentation • Symbolic data: nomenclature scheme Overview of Annotating Cardiopulmonary Anatomy Fiducial markers on bromide images made at time of specimen preparation
Allows two or more users to cooperatively annotate image(s) over the network • Full event synchronization among users • Users can collaboratively annotate structures within the image • Synchronization of file loading and metadata state • Define image areas using irregular polygons, circles and rectangles, to associate with metadata & unique object IDs • Session “catch up” for new users joining existing sessions Collaborative Image Browser/Annotator
Nomenclature Scheme • One goal of collaborative annotation is a logically organized database of embryologic terms • We adhere to such a scheme, although this is in itself a research area of which we are a part. • Collaborating with Cornelius Rosse and Jim Brinkley at the University of Washington, we are establishing a model semantic framework for naming embryologic structures For example: • embryo => organ system => cardiovascular system => heart =>primitive ventricle => future left ventricle • embryo => organ system => cardiovascular system => heart =>atrio-ventricular cushion tissue => ependymal cushion tissue =>bulbar cushion • embryo => organ system => cardiovascular system => heart =>bulbus cordis => rostral half =>conotruncus

GroupVisualization Allows multiple users over the net to explore 3D annotated datasets • Visualization and knowledgebase query sessions are synchronized among users • Will be evolved into a platform for group consultations • Will be integrated with the annotation tools to facilitate gene expression mapping on canonical datasets
3D Group Visualization • Synchronized control of rotation, slicing, and object-voxel queries
3D Group Visualization • Forms a morphological matrix for spatial mapping of gene expression activity
