I have some dicom images from Phillips AlluraXper that are stored in Conquest server. I cannot read that images. I tried with radiant viewer and it say that are no dicom images. Dcmdump read all tags but i can view in viewer.

i tried dcmdjpeg to decode compressed file. here is the error

D: $dcmtk: dcmdjpeg v3.6.1 2016-06-30 $
D:
I: reading input file test.dcm
D: DcmMetaInfo::checkAndReadPreamble() TransferSyntax="Little Endian Explicit"
D: DcmDataset::read() TransferSyntax="Little Endian Implicit"
W: Found element (2001,9000) with VR UN and undefined length, reading a sequence with transfer syntax LittleEndianImplicit (CP-246)
W: Found element (2001,1069) with VR UN and undefined length, reading a sequence with transfer syntax LittleEndianImplicit (CP-246)
W: Found element (2003,102e) with VR UN and undefined length, reading a sequence with transfer syntax LittleEndianImplicit (CP-246)
D: DcmItem::checkAndUpdateVR() setting undefined VR of PixelData (7fe0,0010) to 'OW'
I: decompressing file
F: Pixel representation cannot be changed: decompressing file: test.dcm
F: Input transfer syntax Little Endian Implicit not supported

I tried to use dcmconv to convert file

λ dcmconv -d -ui +uc test.dcm zzz.dcm
D: $dcmtk: dcmconv v3.6.1 2016-06-30 $
D:
I: open input file test.dcm
D: DcmMetaInfo::checkAndReadPreamble() TransferSyntax="Little Endian Explicit"
D: DcmDataset::read() TransferSyntax="Little Endian Implicit"
W: Found element (2001,9000) with VR UN and undefined length

W: Found element (2003,102e) with VR UN and undefined length
D: DcmItem::checkAndUpdateVR() setting undefined VR of PixelData (7fe0,0010) to 'OW'
I: load all data into memory
I: set output transfer syntax to input transfer syntax
I: check if new output transfer syntax is possible
F: no conversion to transfer syntax Little Endian Implicit possible!


Can someone help me?
Thanks

dcmdjpeg cannot decompress the DICOM image since - apparently - it is not JPEG compressed (TransferSyntax="Little Endian Implicit").
I don't know why the "radiant viewer" cannot display the image. Maybe, you should raise this question to the "radiant people"?
