Doubt regarding: RT-Dose DICOM pixel data representation

#1 Post by abhishek_gupta » Wed, 2013-08-28, 11:31

Hello Everyone,

I have recently came across an RT-Dose DICOM where pixel data representation of few frames is UINT8 and for others is UINT16. Is it possible to have this kind of data?? If yes, then is it possible to make pixel representation unique because I need to feed this data into MPR visualization pipeline.

If some more information regarding DICOM is required. Please let me know.

Regards,
Abhishek.

Although this question is more related to the DICOM standard (and not to the DCMTK). here are the relevant sections from part 3 of the DICOM standard:
C.8.8.3.4.3 Bits Allocated
For RT Doses, Bits Allocated (0028,0100) shall have an Enumerated Value of 16 or 32.

C.8.8.3.4.4 Bits Stored
For RT Doses, Bits Stored (0028,0101) shall have an Enumerated Value equal to Bits Allocated (0028,0100).
That means, 8 bits are not allowed.
