Hello,
when doing some MESA tests (see
http://ihewiki.wustl.edu/wiki/index....ities_in_Study)
we have run into a problem with a dicom image used in the tests
(CR1S1IM1.dcm).
There exist the control character 0x9F in the ImageComments field
(0020,4000).
Reading the dicom standard 08-05pu.pdf Section 6 I found out that
characters outside the default charcter set (=ascii) have to be
indicated by the 'Specific character set attribute' (0008,0005) and
that control characters from the C1 set shall not be used at all (see
page 18).
Whenever I try to convert the image to xml with the dcm2xml utility I
get following error message:
> ./dcm2xml.exe error.dcm
dcm2xml: error: (0008,0005) Specific Character Set absent but extended
characters used in file: error.dcm
When adding any extended charset with the '+Ca' option to dcm2xml the
conversion to xml succeeds.
Since the character is there and no specific character set is defined
I wonder whether this specific DICOM image conforms to the DICOM
standard ? Or do I misinterpret the standard here ?
thanks in advance,
Arno Wilhelm
P.S.:
Here is the dump of the dicom file:
