Image type in DICOM Standard MONOCHROME1 and MONOCHROME2

[buiductoan]

Hello everybody, I have a question for image type in dicom standard. In the dicom document I found image type has five types which are :

• MONOCHROME1
  MONOCHROME2 MPEG2 -single component data
  YBR_ICT
  YBR_RCT
  YBR_PARTIAL_420 MPEG2 -multi-component data

If image type in dicom file is MONOCHROME1 or MONOCHROME2, Is it compress or not compress? And What are different between two type: MONOCHROME1 or MONOCHROME2? Thanks

You have no idea about the DICOM basics, right? What you call "image type" is the "photometric interpretation" (see DICOM part 3). Compression is defined by the "transfer syntax" (see DICOM part 5).

Please don't do any software development in this field unless you read and understood the specs!
