    This set up is designed to allow you to project/share cases in a seperate window whilst controlling/tracking their display from this page.

    +

    First you will need to open the linked viewer window by clicking the 'Open Viewer Local' button. This will open a new window/tab with the viewer in it. You will probably need to detach this from your current window.

    +

    If you are sharing the window you can maximise the screen area by hiding the tab/bookmark bar and the address bar. In Microsoft Edge this can be done by installing as an app, in Chrome you can use an extension such as Open-as-Popup.

    +

    Click on the 'Load' button to open the case in a the linked window. Loading subsequent cases/series will replace the first case in the window.

    +

    It is also possible to open a single series by clicking on the 'Load' button next to the individual series.

    +

    Once opened the case details will be show on the right hand side of the page.

    + +
