RadiAnt DICOM Viewer

Navigation: Appendix > Configuration files


Scroll Prev Top Next


The overlay.xml file can be used to change the default annotations displayed over images in RadiAnt DICOM Viewer.


It is located either in the "C:\ProgramData\RadiantViewer" (Windows 7, 8, Vista) or "C:\Documents and Settings\All Users\Application Data\RadiantViewer" (Windows XP) folder.


When RadiAnt DICOM Viewer is used as a patient CD/DVD viewer, the overlay.xml file can be also placed in the "COMMON" folder on the CD/DVD media.


Sample file:

<set>                a collection of annotations grouped in four corners of the image panel


<set> attributes:

"m"                modality (a set is considered as default if the "m" attribute is missing)

"c"                c="0" - set defined for static images, c="1" - set defined for CINE mode

"e"                e="0" - set overwrites default set, e="1" - set extends default set


<tl>                top left corner

<tr>                top right corner

<bl>                bottom left corner

<br>                bottom right corner


<i>                single row - can be one of the predefined annotations or a collection of elements (texts and DICOM tag values)


<i> attributes:

"r"                row index (0 ... n), starting from the panel border (0 - a row closest to the border)

"a"                1 - the row is hidden when anonimization is enabled

"c"                font color: 0 - yellow, 1 - red

"d"                1 - the row is hidden when the included DICOM element(s) is missing


"s"                if present, one of the predefined annotations is used:


01                Current image number and total number of images in the viewport (e.g. "3/237")

02                Current series number (e.g. "Se: 4")

03                Lossy image compression info (e.g. "Lossy compression (JPEG 2000)")

04                Patient name (without ^^^)

05                Patient birthday and sex (e.g. "1952-02-09 M")

06                Rotation/flip info (e.g. "R: 90° CCW F: H")

07                MRI TE and TR times (e.g. "TR: 540.0 TE: 14.0")

08                MRI strength of field (e.g. "FS: 1.5")

09                Image acquisition date and time (or study date and time if acquisition timestamp is not available) (e.g. "2009-12-03 19:23:12")

0A                Thickness and location of the image (e.g. "T: 5.0mm L: -68.7mm")

0B                Positioner angles (e.g. "LAO: 9 CRA: 27")

0C                Mouse cursor position (in DICOM image coordinates) and value of the DICOM pixel under cursor (e.g. "X: 139 Y: 281 Val: 105")

0D                Window width and level info, window preset, negative mode (e.g. "WL: 40 WW: 80 [CT Brain]")

0E                Current real FPS (frames per second) value during CINE run (e.g. "15 fps")

0F                X-ray tube current in mA and peak kilovoltage output of the x-ray generator(e.g. "330mA 120kV")

10                3D cursor position in milimeters (e.g. "X: 28.94mm Y: -6.12mm Z: -487.03")



<e>                single element (a text or a DICOM tag value)

<e> attributes:

"k"                1 - DICOM tag value, 2 - text element

"i"                DICOM tag ID (group and element hex values), valid only if k="1"

"t"                a text, valid only if k="2"


an example of a row consisiting of the text element and the DICOM tag value:

<i r="3" d="1"><e k="2" t="Body part examined: "/><e k="1" i="00180015"/></i>
