Hi all,
is there a way to modify DICOM Tags of a written DICOM file only? Without modifying the Pixel Data.

What I'm doing is:
I'm processing 12bit rawdata to 16bit dicom bitmap.
When I save the file ImageEn writes:

0x0028, 0x0100 = 16 (Bits allocated)
0x0028, 0x0101 = 16 (Bits stored)

What I need is to change 0x0028, 0x0101 to 12.
But ImageEn always writes both entries to 16.

Is there a way to save the metadata to the file without "resaving" the image data?

Thanks in advance
Alex

Hi Alex

There is not a way to modify only the DICOM tags at this time. It is on the to-do list for a future version.

Hi,

Any news on this? Another usecase for modifying dicom tags tags without changing image data is anonymizing dicom files.

Regards, Ronald

Hi Ronald

This feature has not yet been implemented, but I will elevate its priority.

Note: If you use one of the lossless compression options then your image data should not be affected:

Just wondering if there is a rough estimate of when this feature will be made available? Thank you.

Hi

It will be a significant implementation, so I cannot comment at this time when we'll be able to add it.

Note that injection is only relevant if your DICOM_Compression is a lossy format such as iedcJPEG or iedcJPEG2000. So you can save to a non-lossy format such as iedcUncompressed, iedcRLE or iedcLosslessJPEG2000.

In v9.3.2, you will be able to inject tags into DICOM files (single frame DICOM images only at this time).
