Setup AETitles

It is easy to set up a PACS to send images to RadPix teaching file system. A PACS admin will have to add a DICOM SCP (destination) that includes:

  • IP Address of RadPix server
  • AETitle can be set to anything, i.e. “RadPix”, “TeachingFile”, etc. (No spaces allowed)
  • Title of the Destination can be set to something that makes sense to the end user: “Teaching File”, “My Teaching File”, etc.
  • Port number of RadPix Server, default 1090.


When many cases are sent to the server, it is sometimes difficult to find the ones you are looking for.  It is possible to set up multiple DICOM destinations on a PACS using only 1 IP address and port number, but with multiple AETitles.  The different AETitles can then be used when images are sent to the RadPix server and subspecialty tags can be placed on the cases.  This is well described in section (DicomImportService) of the RSNA Wiki


For instance, set up multiple Destinations as follows, each with the same IP number and port number:

  • AETitle : “Neuro”   Destination Title “Neuroradiology Teaching File”
  • AETitle : “Genitourinary”   Destination Title “Genitourinary Teaching File”
  • AETitle : “Gastrointestinal”   Destination Title “Gastrointestinal Teaching File”

The user will then select one of these 3 send destinations.  The draft cases will then be tagged with “Neuro”, “Genitourinary”, or “Gastrointestinal” depending on the destination the images were sent to.  At this point, the user can then click one of the filters on the left side of the page.

All subspecialty names in the left column can be used as AETitles.

This is set up by the following default configuration.

The default system config.xml file, located in {server installation path}/CTP contains:

<Pipeline name=”DICOM Service Pipeline”>

<DicomImportService calledAETTag=”00120010″ callingAETTag=”00120020″ throttle=”0″ logConnections=”no” logDuplicates=”no” suppressDuplicates=”no” >


The called AET Tag value is put into the DICOM group 0012 and element 0010.  This is the DICOM tag where the AETtitle “neuro” or “genitourinary” is placed. The calling AET Tag value can also be saved, and is put into the DICOM group 0012 and element 0020 in the example above. This could be useful if workstations are individually configured to send to the RadPix server.

XML Template

When the images are received, the AETTags are used in the generation of the XML data file for a case.  There is an XML field that is used by the server to define the specialty or subspecialty of the case.  The generation of these data files is based on a template file,  DicomServiceTemplate.xml, which is located in {server installation path}CTP\mircsite\storage\ss1.  The category tag is a child of the main MIRCdocument tag.

<MIRCdocument display=”mstf” first-tab=”2″ temp=”yes”>

<category><g0012e0010 desc=”Category”/></category>


When a series of images is sent to the DICOM destination with an AETitle of “genitourinary”, “genitourinary” is placed into the DICOM header of each image in Group 0012, Element 0012.  When the MIRC document is then created, the contents of Group 0012, Element 0012 are placed into the XML document as directed above, resulting in:

<MIRCdocument display=”mstf” first-tab=”2″ temp=”yes”>



The subspecialty fields on the on the left side of the main query page can then be clicked to filter the cases by subspecialty. The 4th column in the example below, shows GU (yellow) and GI (green) cases with those values having been automatically added via the AETitle.

By selecting one of the check boxes on the left side of the screen for subspecialty (or modality), the query results can be filtered.

In a similar fashion, the modality tag is filled in automatically from the DICOM header tag (0008,0060) as the XML is being generated.

<modality><g0008e0060 desc=”Modality”/></modality>
