  		Fig. 1. —This schematic shows image acquisition. When startftp command on Advantage Windows workstation is invoked, proxy file transfer protocol (FTP) server initiates IDL_FTP graphical user interface (GUI) via Xwindows connection. Proxy FTP server polls film directory on Advantage Windows workstation for images that were dragged by user to film composer. These images are sent to proxy server, converted to tagged image file format (TIFF) images within IDL (Research Systems, Boulder, CO), and then sent to client computer (i.e., Macintosh [Apple Computer, Cupertino, CA] or PC). Searchable patient database text log is automatically created and updated on both proxy FTP server and client computer reflecting patient information, folder location, and number of images transferred.
