findAndGetUint16

[qs5d]

I want to change the value of DCM_InstanceNumber, ie. the number of the image by using the following:
Uint16 value;
findAndGetUint16 (Dcm_InstanceNumber, value);

But I couldn't get the value I want. Could you please give me an example? Thank you.

According to part 6 of the DICOM standard, attribute InstanceNumber has a datatype/value representation of IS (integer string).

Function findAndGetUint16(...) is applicable to OW and US attributes only (see comment in dcmdata/include/dcitem.h).

You should use findAndGetOFString(...), which is applicable to AE, AS, AT, CS, DA, DS, DT, FL, FD, ___IS___, LO, LT, OB, OF, OW, PN, SH, SL, SS, ST, TM, UI, UL, US and UT, instead. See comment in dcmdata/include/dcitem.h for more information.

You can also use findAndGetSint32().
