DICOM to HL7 with embedded image

[smyers119]

Working off of other's success I almost have this figured out but need help with the image. It does not appear to be embedding the jpeg correctly.

This is the results of a test DICOM i run through my channel:

Could you share a bit more of your channel logic, e.g. the field mapping between inbound DICOM and outbound HL7 message?

Maybe this already helps (source transformer script):

// DICOM images sometimes come wrapped in 2 attachments where the 2nd is the image
// http://www.mirthproject.org/community/forums/showthread.php?t=218075

logger.debug(msg.toString());

// get attachments
var attachments = AttachmentUtil.getMessageAttachments(connectorMessage);
var attachmentsSize = attachments.size();
//logger.debug("Message ID " + connectorMessage.getMessageId() + " attachments: " + attachmentsSize);

var jpg = "";
// extract image from last attachment
var attachment = attachments.get(attachmentsSize-1);
jpg = FileUtil.encode(attachment.getContent());

if(attachmentsSize == 0 || jpg == ""){
	logger.debug("No DICOM image attached, ignoring message.");
	destinationSet.removeAll();
	return;
}

// Store embedded JPG image in channelMap (bytes encoded as base64 string)
$c('jpg', jpg);
