Sending Exams: .ONX or DICOMOnyx-RAD supports two different methods of sendingexams: standard DICOM or a proprietary method we simplycall .ONX.DICOMSending DICOM results in standard DICOM format andstandard DICOM functions (like CSTOR, CMOVE, etc.).Any recipient who claims DICOM compliance can receivesuch exams. The only disadvantages to sending exams inDICOM format are:• Lack of progress monitoring, as the DICOM standarddoes not provide for this• Onyx-RAD does not send DICOM over phone line,due to the standard’s lack of provision for suchfeatures as auto-resume and validity checking• Lack of security (no encryption).ONXTo compensate for the shortcomings in the DICOM standardmentioned above, Viztek developed its own transfer syntax,.ONX, which provides these features:• Progress monitoring• Auto-resume features• Validity checking on each image• Secure encryptionIt is recommended that you utilize the .ONX transfer syntaxwhen sending exams to other Onyx-RAD sites.Onyx-RAD is a registered trademark of Viztek, Inc. © 1995-2002 Page 121
