The eFilm Blog

eFilm 3.0 now allows you to customize the overlay.  You can display any DICOM tag - as long as it is being stored in the DICOM header!!!!

Below is an explanation of how to do this.  We will use the example of the “Flip Angle” tag, which is not normally displayed in eFilm.   The Flip Angle is a tag commonly stored in the DICOM header of MR images.

To add “Flip Angle” to the Overlay: 

• Open the desired image and make a note of the Group-Element of the desired Tag from a DICOM Dump. 
  • To view the DICOM header, select the specific image and click on Utility -> DICOM Dump
  • E.g.: Flip Angle has a Group-Element: (0018, 1314) 
• Now close the DICOM Dump.
• Click Edit-> Properties -> Modality Settings -> Overlay
• Select the specific Modality Type. (MR in the above example) 
• Now, we will define our own Display Item (Define the Tag) 
  • Under <USERDEFINEDITEMS> tag add a new <DISPLAYITEM> tag. 
  • In the above example the tag should look like this..

 ———————————

<DISPLAYITEM tag=”0×00540018″ item=”EnergyWindowName”/>

<DISPLAYITEM tag=”0×00540400″ item=”ImageID”/>

<DISPLAYITEM tag=”0×00181314″ item=”FlipAngle”/>

 </USERDEFINEDITEMS>

 ———————————   

Where 0×00181314 is the Group-Element of the Flip Angle tag.

 

• Once the definition is done click on Save and make sure it’s saved without errors. 
• Now place the defined tag to be displayed in a specific quadrant. 
  • There are four quadrants in any view port.
    • TL: TOP LEFT          TR: TOP RIGHT
    • BL: BOTTOM LEFT    BR: BOTTOM RIGHT

 For example let’s place the Flip Angle tag in Bottom Left quadrant.

——————————- 

<QUADRANT location=”BL”>

<ROW><OVERLAYITEM item=”SliceThickness” postfix=”thk/”/>

<ROW><OVERLAYITEM item=”RepetitionTime” prefix=”TR: “/></ROW>

<ROW><OVERLAYITEM item=”FlipAngle” prefix=”FLIP ANGLE: “/></ROW>

</QUADRANT>

——————————- 

•  Postfix / Prefix are user defined and are used to name a tag on the overlay. In absence of this only the tag value will be displayed

 

Once complete, you should now be able to see this specific tag in all studies that match the modality in question!!
