Configuring FieldCenter
Look at Parameters
Once you have FieldCenter running on your machine, go to the Parameters tab. Copy down the local DICOM Store Information.
Trial information
Switch to the Control Panel tab and the Trial subtab. Enter the Dicom Store AE Title in Trial Name. Enter the MIRC Document Base URL in the Destination URL field.
Local DICOM SCP Information
Now go to the DICOM SCP subtab. If you need to, change the data here to reflect your local DICOM SCP settings. But it should probably stay the same as the settings you saw on the Parameters tab.
Anonymizer
The FieldCenter application includes an anonymizer. The anonymizer allows you to hide or modify selected dicom header values. To enable the anonymizer, go to the Control Panel and select the Anonymizer subtab.
To alter the anonymizer settings, go to the Special tab and select the Anonymizer subtab.
The TRIAL parameter should be the name of your clinical trial.
The SITENAME parameter should be the name of your site.
The SITEID parameter should the hospital ID.
You will also see a list of all the dicom headers. To select a header to include, check the checkbox next to the header. To apply a script that alter's the header's value, type the logic in the text box to the right. The @keep() script preserves the header's value.
For more information on how to configure the Anonymizer and a list of all the logical commands you can apply to DICOM headers, click here
If you change the anonymizer scripts, do not change the contents of the ReferringPhysicianName field. The anonymizer uses this element, which is not used in the trial, to indicate that it has already processed a file.
Uploading DICOM Images Through FieldCenter
Go to the Special Tab and the Selector subtab. Select a dicom file or directory to upload from your local drive and click the Queue button. You should see details appear in the text area on the right.
The FieldCenter window has to remain open or active when sending DICOM studies to be routed to the CVRG.
Checking Submission Status in FieldCenter
Go to the Queue tab to see the status of the image queue, and the Event Log tab to track the events.
MIRC
Once the images are submitted through FieldCenter, they will be routed to the MIRC system. MIRC will then forward the images on to XNAT.
Viewing Image Transfer Progress
If you have an account in MIRC with admin rights, you should be able to view the progress of the images flowing through the MIRC system by going to the Admin menu, selecting Storage Service Admin, and then selecting HCM Mirc Storage Service.
Once in the Storage Service Admin, click the Show Log button under DICOM to enter the DICOM log. Here you will see the images that have been imported.
Searching and Viewing Images
Returning to the main page in MIRC, if you search for the images you uploaded, you should see them in the results.
Click then name of the image and you should get the details and be able to view.
Download the Entire Dicom Series to your local workstation
To download a dicom series to your local workstation, click the Export button in the Document tab and wait patiently for the series to download. Then click the save button when prompted.
Manually Forward images to XNAT
To manually forward the image to XNAT, click the Document tab and then click the To DICOM SCP button. The image should be forwarded to the DICOM SCP configured in the DICOM Export Service.
XNAT
Once the images are in XNAT, log into XNAT and go to the Prearchive section.
XNAT Prearchive
You will see a list of images in the PreArchive area.
Depending on the dicom header information, XNAT may route the data automatically to a particular project. Otherwise, it will be in the unassigned section.
You may route the image to a particular project by using the drop-down menu that says "Move to..."
Archiving an Image in XNAT
To submit the image to the XNAT archive, click the hyperlink on the image name. That will take you to the image details section. Then click the Submit button.
