Which format for the bad pixel image (Dicom Tag 0014,3080) file format

I wrote a Dicom/DICONDE file library. Now I would like to add a bad pixel image into the file.

According to Dicom standard part06, the bad pixel image is to be stored in tag 0014,3080 with data type OB. But what is the exact format? I guess it is one bit per pixel, 0 means pixel OK, 1 means bad pixel.

Can someone confirm that? Where can I find some sample Dicom files containing a bad pixel?

EDIT: ASTM E 2339-15 do not specify the bad pixel image format.

Any advice appreciated.

Solution

  • The bad pixel image format is described in ASTM E 2767-11 document in table 5. This is exactly as I expected: Byte image with the same number of rows and columns as the Pixel Data (7FE0,0010). The pixel data of this image will contain a "1" for a good pixel and a "0" for a bad pixel.
