ZEN Browser server-based virtual microscopy image databasing software from Carl Zeiss Microscopy (Thornwood, NY) aids researchers in storage, filing, organization, and backup of large digital microscopy data sets. The software, which has utility in pathology research, provides storage and organization for large virtual slide databases. An intuitive web interface enables organization of virtual microscopy data online and across platforms. The software is accessible through any Internet browser, and is password-protected for security purposes. An additional user management function restricts access to authorized individuals only, while allowing others to view images without administrative rights. All images are filed together with relevant metadata and customizable supporting documents.
