HL7 ORU & DCM4CHEE

[Yavindu de alwis]

Hi,

I found a sample ORU message to pass report(Structured Report Filled by a Doctor after examine DICOM image) details to DCM4CHEE.

I don't understand how DCM4CHEE attach these OBX details(report details) to particular a study or to dicom images because this message does not include the Study IUID or did I misunderstand something.

Hello,

If study UID is not present, the DCM4CHEE archive creates a new study and these details you find in the object's attributes.

[Yavindu de alwis]

Thanks for reply.

That means I have to pass ZDS tag as well with Study IUID.Is that so ?

[vrinda...@j4care.com]

The http://ihe.net/uploadedFiles/Documents/Radiology/IHE_RAD_TF_Vol2.pdf#page=286 does not mention any ZDS segment. Attached a sample ORU^R01 message

[Yavindu de alwis]

Thank you so much.

Vrinda is talking about dcm4chee-arc-5.x, I do not remember the behavior of the ORU to SR import of dcm4chee-2.x.

I think DCM4CHEE uses Accession Number and Requested Procedure ID to match a SR object to an existing study. From the IHE:

"Each Requested Procedure is identified by a Requested Procedure ID that needs to be unique only within the scope of the Filler Order Number/Accession Number."

Where: "Requested Procedure: Unit of work resulting in one report with associated codified, billable acts."

DCM4CHEE uses Accession Number: http://www.dcm4che.org/jira/browse/DCMEE-3
this is apropriate approach because reporting systems offen doesn't know anything about SUID

[Yavindu de alwis]

Is this a valid ORU ?

yes it is, you need to map in oru2sr accessionnumber field
eg.:
 <xsl:template name="const-attrs">
...
        <!--Accession Number-->
        <attr tag="00080050" vr="SH">
            <xsl:value-of select="string(OBR/field[2]/text())"/>
        </attr>

I wanted to try and send the ORU through Mirth as well to DCM4CHEE to see how the report looked.  See the screenshot:  https://www.dropbox.com/s/5ku1e0nk29c9y1j/Screenshot%202017-04-05%2014.50.12.png?dl=0

What is supported for the History, Findings, etc?  

What is also strange is that the DOB is not what is in the ORU, but I have purged the lines in DCM4chee as it is a new install.  I have resent 8 different times.  Clearly something off here.  I have not changed the xls ... only to look at the accession to see if it would add it to the table above, but no luck.

DICOM SR are rendered with Apache FOP - the default stylesheet (../conf/dcm4chee-rid/fobsr.xsl)  produces the report you provided.
