4 Main focus of.slide.slide: Where is the main focus: Image Quality Speed Upgradeability Flexibility

5 Which features are necessary? Seamless image stitching and optimal focus Flexible use of the BX light microscopes Selectable resolution e.g. 2x 4x 10x 20x 40x 100x Different observation methods (brightfield, fluorescence,..) Simultaneous processing of many tasks Memory management for very large images Speech, text and drawing annotation High colour reproducibility using ICC profiles Virtual slides accessible from anywhere at any magnification

6 Digitization example: typical sample viewing with 40x objective microscope can display a small field of view only Y o u r V i s i o n, O u r F u t u r e.slide what are the requirements

7 Digilization display would need about 9000 Monitors (17 ) image size about x pixel image was generated by 4500 single snapshots ~1GB image size an 15GB uncompressed image size.slide what are the requirements ~ 22.5 m ~35m

8 Multilayer scan with.slide Single layer versus Multi layer scan Conventional virtual slide scanner Olympus.slide system

9 Multilayer scan with.slide conventional single layer scan 1 scan = 1 image n scans = n images 10x 20x 2x vsi image 40x 10x vsi image 20x vsi image 40x vsi image

10 Multilayer scan with.slide Multi layer scan n scans = 1 image clear defined position where a high resolution detail scan was taken 10x 20x 40x overview

11 Virtual z stacks with.slide under development Z stacks focussing on a virtual slide Z stack Z stack

12 Net Image Server for.slide Net Image Server security with password and user login direct accessing of image files via LAN/WAN Images accessible by :.slide viewer OlyVIA Webbrowser (flash) Not only vsi files can be used, ALL standard image formats Must be able to integrate into existing image databases

13 OlyVIA Viewer for Imaging Applications OlyVIA viewer software: Remote access to.slide image server via LAN/www convenient: dongle less for free fast downloadable easy to use high speed image transfer over the LAN/WAN high image quality annotations, text and sound available over the LAN/WAN image synchronization even with multiple image server

19 .slide applications what's the purpose for Digital virtual Microscopy? Research cancer research pharmacological research neuroscience research

20 .slide applications what's the purpose for Digital virtual Microscopy? Research (cancer, pharmacological, neuroscience) High throughput, high content applications TMA (Tissue Micro Array) analysis Image analysis on large field of views

21 .slide applications what's the purpose for Digital virtual Microscopy? Histology/Pathology laboratories & hospitals Clinical environment, HIS&PACS integration

22 .slide applications what's the purpose for Digital virtual Microscopy? Histology/Pathology laboratories & hospitals Archiving of rare and valuable samples Collaborative working second opinion & discussion validation of results done by remote located experts Routine pathology workflow

23 3 main fields of application 1) education 2) clinical Research 3) hospital environment

24 Internet Y o u r V i s i o n, O u r F u t u r e.slide for education Student courses and examines made on virtual slides Clients e.g. students PC or laptop Communication from the client via LAN to the central Database Teacher

25 Internet Y o u r V i s i o n, O u r F u t u r e.slide viewing, conferencing / consulting Communication is more important than ever Access to images: anytime anywhere

26 .slide conferencing / consulting Conferencing (1:N): For education / discussion of images 1 administrator edits the image Annotations Snapshot areas N users watch the scene Administrator can give the edit right to any conference participants Consulting (1:1) ask for a second opinion Workflow: 1. Use annotation tools to: 1. Define interesting areas 2. Ask/answer questions 2. Save image to server 3. Notify discussion partner

27 .slide at customers site education high performance of the Net Image Server software needed Performance tests have been made by OT : measuring CPU load, disk I/O load and bandwidth load when accessing 25 slides by 25 clients at the same time student exams have been performed with 96 clients at Japan Universities online reference databases have been created in EU (France, Germany, Spain) integration of virtual slides with the Net Image Server into one of the largest European online histo pathology database is under construction the WHO is evaluating to publish their slides with the Net Image Server

30 .slide at customers site research high flexibility due to different applications different focus algorithm necessary compatible file formats Image processing (geometrical functions) EFI and z stacks fluorescence illumination needed Neuropathology research TMA scan for cancer research Pharmacological companies

31 .slide in routine hospital environment under evaluation Complete integrated solution for pathology institutes Integration of.slide via HL7 / DICOM Open vsi images of a specific patient from the patient linked database Cross talk between.slide image database and patient linked database cooperation with the market leader in each country is necessary

32 .slide at customers site clinical routine under heavy discussions at the moment due to incompatibility of whole slide image file formats waiting until DICOM modality for pathology is defined only pilot projects have been implemented as research & evaluation projects with some hospitals

33 Image Database for pathology under evaluation Image acquisition and insertion to Database Scanning samples with.slide Assignment of Case ID (manual or via Barcode) Collect patient data via HL7 (Patient, case, etc) Automatically. insert Images and metadata to DB pathology Information system Image assessment Image Database Retrieval of image of interest (+reference images Virtual microscopy With.slide Diagnosis input Update of data In image DB And in PIS(HL7)

34 .slide specs&info optical unit: BX2 microscopy technology with selectable magnification. High resolution objectives, UPLSAPO 10x (N.A. 0.16), 20x (N.A. 0,75), 40x (N.A. 0.9) CCD camera: peltier cooled 2/3 CCD camera with 6.45 µm pixel size Workstation: high performance dual Xeon workstation with 500GB data storage capacity 20.1 high resolution TFT monitor typical scan speed for 10mm x 10mm sample with 20x objective: less than 1.5 min with standard resolution (0,5µm/pixel) optional: high resolution scan 0.32µm/pixel, less than 3 min selectable image compression during scanning: Data compression takes place during the scanning process without any time delay. The compression ratio and compression type, like like jpg, jpg2000, can be adjusted or even switched off. Focus map Focus points are taken automatically and only where the tissue is. Different focus map algorithm assure optimal image quality Tissue finding Automatic
