#149 Retrieving DICOM Tags - 2D

[Subhra Sundar Goswami]

Is there any function to retrieve dicom tag values? Wanted to retrieve the tag values from a 2d Dicom image file for the tags listed below. A dicom image has been attached as example:

Distance Source to Detector 0018,1110
Distance Source to Detector 0018,1111
Imager Pixel Spacing 0018,1164
Positioner Primary Angle 0018,1510
Positioner Secondary Angle 0018,1511
patient orientation 0020, 0020
rows: 0028,0010
columns: 0028,0010

These tags are also of interest:

sliceThickness 0018,0050
sliceLocation: 0020,1041
TemporalPositionID: 0020,0100
NumberofTemporalPositionID: 0020,0105
image position patient: 0020,0032
patient orientation: 0020,0037 / 0020,0020
patient position: 0018,5100
primary angle increment: 0018,1520
secondary angle increment: 0018,1521

Possible options to solve this:

• the DICOM plug-in reads all tags

  • ugly, because DICOM is very generic

• An external table provides the information for all tags that should be read.

  • has the advantage that no recompilation is needed if new tags are added to the list

• The application should set the tags it really needs.

  • has the advantage that each application can define its own subset and could make use of an external file

Most of these values are now read, but since a programn that required is so specific, it should probably read this information directly from the DICOM files.
