When a new study is opened, all images in panels and the series preview bar are cleared.
To add new images from different location use the Add DICOM images drop-down menu.
New images can be added from a folder, selected files, or decompressed from a ZIP archive.
Notice that you cannot open directly two or more DICOM CD/DVD disks at the same time - when the first one is ejected, the images become unavailable for viewing. If you want to open more than one disk at the same time, first you need to copy their contents to a folder on your hard drive and then scan the folder for DICOM files.
