Problematic Phillips files

[Daniel Carrion]

Just wondering if anyone has any thoughts on issue I'm having with privates in a DICOM file coming out of Phillips unit. Here's the problematic section from dcmdump.

The error I'm seeing when reading in ruby-dicom:

WARN -- DICOM: The actual length of the value (0) does not match its specified length (-1) for Data Element 2001,9000

Here's the output from dcmdump:

Hex output if it helps:

Hello Daniel

Thank you for reporting this issue.

I believe this may actually be fixed in the github master branch (unforturtunately unreleased yet). If you are comfortable with how to do this, you could check out the code from here and give it a go:

https://github.com/dicom/ruby-dicom

Anyway, I would be interested to give this particular dicom file a go, perhaps add it to our test samples. Would it be possible to send me a copy?

Best regards,

Chris
