11/30/2023 0 Comments Wireshark protocol filter list![]() ![]() Since the SOP Class UID (0008,0016) and SOP Instance UID (0008,0018) are mandatory elements in the meta header, they are created if needed. Make sure to be in the parent directory and only highlight the target directory, don't open it.įor the DICOM Export, following UIDs are used. The Save all dialog is a little tricky, if the 'Browse for other folders' is expanded. Then, select File -> Export -> Objects -> DICOM.ĭepending on the minimum size defined in the preferences, you will see more or less items in the list. However, if you know the TCP port used (see above), you can filter on that one.Ĭapture only the DICOM traffic over the default port (80): tcp port 104 DICOM Exportįirst make sure to have a valid DICOM capture, including Association Request. You cannot directly filter DICOM protocols while capturing. Show only the DICOM based traffic: dicom Capture Filter However, when one wants to see, the detailed tag decoding, or more important, if one wants to search for very specific DICOM attributes, enable this setting.Ī complete list of DICOM display filter fields can be found in the display filter reference By default it is disabled, as it does not add much information. when using TShark to create a text output.Ĭreate subtrees for DICOM Tags: This is a matter of personal taste. Deselect this option, if you prefer a flat display or e.g. For a few items, containing tags are summarized and shown as an item description. Since IODs can span multiple PDUs, sequence items in subsequent PDUs, may appear as root object. If enabled, each sequences and items are shown in a hierarchy as show next. DICOM commands are prefixed with a Meta Header as well.Ĭreate subtrees for Sequences and Items: This is a matter of personal taste. Set it higher, to just export DICOM IODs (i.e. Set it to 0, to see DICOM commands and responses in the list. item size in bytes to export: Do not show items below this size in the export list. for command PDVs), wireshark specific ones will be created. If the captured PDV does not contain a SOP Class UID and SOP Instance UID (e.g. If despite this enabled, the communication is still not recognized as a DICOM stream, add the TCP port to the list above.Ĭreate Meta Header on Export: For exported PDUs, create a DICOM File Meta Header according to part 10. If you frequently look at DICOM traffic, enable this setting. This is disabled by default, to preserve resources for the non DICOM community. Search on any TCP Port: When enabled, the DICOM dissector will parse all TCP packets not handled by any other dissector and look for an association request. Preference Settingsįollowing settings are available to influence DICOM dissection.ĭICOM Ports: Comma separated list with TCP ports to decode. It can export captured DICOM objects as filesĬurrently, the biggest issue is still the proper reassembly of more than one PDU.It decodes all tags defined in the standard 2008.Starting with Wireshark 1.2.1, the DICOM dissector has many new features. SampleCaptures/DICOM_C-ECHO-echoscu.pcap.Keep this file short, it's also a good idea to gzip it to make it even smaller, as Wireshark can open gzipped files automatically. XXX - Add a simple example capture file to the SampleCaptures page and link from here (see below). The accepted or rejected presentation contexts are decoded, to quickly identify negotiation issues. The well known TCP port for DICOM traffic is 104.įollowing screenshot shows a DICOM communication containing a C-ECHO followed by C-STORE request. TCP: Typically, DICOM uses TCP as its transport protocol.For more information about the history, please refer to & Protocol dependencies Previous standards did not include network support. HistoryĭICOM is the third version of a standard developed by American College of Radiology (ACR) and National Electrical Manufacturers Association (NEMA) and was released in 1993. using a DICOM editor, apply the necessary care, as far as the interpretation of the results go. For certain network captures, the different PDUs are not resembled in the correct order, i.e. The exported file are solely for data and communication interpretation purposes, and the implementation does not claim to be a reference. Wireshark is not a Medical Device and therefore exported files MUST NOT be used for any clinical processes. This page will focus on wireshark specific topics. Wikipedia has a very good high level description about DICOM and the protocol specifications can be found at the DICOM Homepage. Digital Imaging and Communications in Medicine (DICOM) ![]()
