"FR" not accepted as value in Patient Orientation [by ldepotter]

DVT:: "FR" not accepted as value in Patient Orientation
Hi,

When I send a mammography image for presentation to DVT with a L-MLO view I get an error stating that the �Patient Orientation� (0020,0020) which has the value �A�,�FR� is incorrect. FR is apparently for part of the list of enumerated values.
However, DICOM states in part 3 C.7.6.1.1.1 Patient Orientation that:

For Patient Orientation each value of the orientation attribute shall contain at least one of the abbreviations. If refinements in the orientation descriptions are to be specified, then they shall be designated by one or two additional abbreviations in each value. Within each value, the abbreviations shall be ordered with the principal orientation designated in the first abbreviations.

See also note 2 that states:

E.g., a medio-lateral oblique projection of the left breast of a human might be encoded with Patient Orientation values of �A\FR� rather than �A\F�, since the plane is obliquely inclined such that the colums are directed both downwards and medially, which for a left breast is towards the right, though the downwards direction is the principal column orientation.

Is there a way to work around this problem in DVT?

Best regards

Ludo

Shutter Shape = Bitmap indicated as wrong in DVT [by ldepotter]

DVT:: Shutter Shape = Bitmap indicated as wrong in DVT
Hi,

When I send a Grayscale Softcopy Presentation State object to DVT, containing a Bitmap Display Shutter Module (To hide the background of a mammo image), then DVT give�s me back an error that has to do with the "Display Shutter Module".
DVT complains that 0018,1600 Shutter Shape hast the wrong value (= Bitmap).

Below this, in the "Bitmap Display Shutter Module" the same attribute 0018,1600 Shutter Shape with value =Bitmap is indicated as correct. (As expected)

Is this a known problem?

Best regards,

Ludo

Hi Marco,

Did someone already create a ticket for this problem and if yes, what is the status today?

cannot get pass on failed storage commitment SCP response [by fschroeck]

DVT:: cannot get pass on failed storage commitment SCP response
Hello,
to test our StorageCommitmentSCP we would like to validate the response if the storage commitment fails. The script is attached.
The problem is, that even if the response is negative, DVT wants the ReferencedSOPSequence. In our research in the DICOM standard we came across PS 3.4-2008, Page 174.:
"When a response is negative the field "Referenced SOP Sequence", is not mandatory and should be present only when there is any positive match"

But when running the script, the result is "failed" and DVT says:
"Type 1 (mandatory) attribute (0008,1199) should be present with at least one value."

I have tried the latest DVT version 2.6.8. Is this a bug in DVT or a problem in our script?

Thank you very much!

DVT:: MPPS Media Validation Failure to recognize SOP Class

Hi,

according to DICOM, you can only store SOP instances from storage SOP classes in DICOM files. DVTk is able to validate the content of exactly these DICOM files.

You are trying to validate a MPPS message that has been stored in a pseudo-DICOM file, created by DVTk. This is not a DICOM file according to the DICOM standard. DVTk supports storing MPPS messages in pseudo-DICOM files to be able to store the data set part of a MPPS message for reuse in e.g. test scripts. And as this is not a valid DICOM file as specified by the DICOM standard, DVTk is not able to validate this and you will get the error messages as described by you.

Marco

DVT:: Problem with PRINT-SCP
Hey!

I'm new to DVT scripting and I received the same error message. It happened while trying to test the C-FIND command using DVT as SCP and a DICOM workstation as SCU. I used the following script :
"

)

)

(0x00000900, 0x0000)
)

RECEIVE RELEASE-RQ

SEND RELEASE-RP
"

and received those errors :

"...

Error: No Command and/or Dataset definition found - validation skipped

Could anyone help me finding out where does the error come from? It's probably a simple error, but as I said, I just started to write my first DICOM scripts.

DVT:: System.OutOfMemoryException when trying to validate .dcm file

Hi,

thanks for letting us know what caused the problem!

Correct attribute lengths specified in a DICOM file and DICOM message is normally critical for correct interpretation of the stream. Depending on the implementation, some applications may handle incorrect attribute length better than other applications.

Trying to recover from these kind of problems is something we already keep in mind if we would decide to create a new architecture/implementation for the coding and encoding of a DICOM stream.

Marco

Re: Definiton file for Breast Tomo. Storage [by marcokemper]

DVT:: Definiton file for Breast Tomo. Storage

LS,

thisis an easy one to answer .

It is already part of the definition files version 1.1.10.

Maybe it just has not been loaded yet. In which application(s) do you want to use this definition file?
