  1. [Philips] Neverending MR Image Storage and Rescale Intercept/Slope

    Hi there,

    Has anyone ever dealt before with such an MR Image Storage (Philips
    Medical Systems) with the following sequence:


    (2001,9000) SQ (Sequence with undefined length #=1) # u/l, 1
    Unknown Tag & Data
    (fffe,e000) na (Item with undefined length #=37) # u/l, 1
    Item
    ...
    (2001,1068) SQ (Sequence with undefined length #=1) # u/l, 1
    Unknown Tag & Data
    (fffe,e000) na (Item with undefined length #=5) # u/l, 1
    Item
    (0028,1052) DS [0] # 2,
    1 RescaleIntercept
    (0028,1053) DS [9.45934065934066] # 16,
    1 RescaleSlope
    (0028,1054) LO [normalized] # 10,
    1 RescaleType
    (2001,0010) LO [Philips Imaging DD 001] # 22,
    1 PrivateCreator
    (2001,1077) CS [LINEARMODALITY] # 14,
    1 Unknown Tag & Data

    Looking at the scalar range of the Pixel Data, it seems ok. So I guess
    this should be safe to always discard them.

    correct ?

    Thanks
    -Mathieu

    I think this is just a repeat of:

    ....
    (0040,9096) SQ (Sequence with explicit length #=1) # 40, 1
    RealWorldValueMappingSequence
    (fffe,e000) na (Item with explicit length #=2) # 32, 1
    Item
    (0040,9224) FD 0 # 8, 1
    RealWorldValueIntercept
    (0040,9225) FD 9.45934 # 8, 1
    RealWorldValueSlope
    (fffe,e00d) na (ItemDelimitationItem for re-encoding) # 0, 0
    ItemDelimitationItem
    (fffe,e0dd) na (SequenceDelimitationItem for re-encod.) # 0, 0
    SequenceDelimitationItem
    ....
