NBIA role required to use this feature: NCIA.MANAGE_VISIBILITY_STATUS
For more information about roles, see Creating a New NBIA User.
When an image is uploaded to NBIA, it is not made public immediately. A curator takes it through a quality control process to ensure that no private patient data is available, the image is of good quality, and so forth. Using the QC tool as a curator, you can define search criteria to locate image series for you to evaluate. You can then evaluate the submission and assign the QC status to an image or image series.
QC tool search visibility
The QC tool allows a curator to search "non-visible" or "not reviewed" images, whereas a regular user using the search tool can only see approved public images.

In the Thumbnails column, click View to see image series details.
The Series Details page appears, displaying the first image in the series on the left and the DICOM tags for the image on the right. If there is more than one image in the series and DICOM tags for each image, you can view an animated slideshow of the images in the series. For more information about the controls in the animated slideshow, see Viewing Image Animation. The DICOM tags change when you view a different image in the series.
If the image series modality is Ultrasound, you can view each image in the series in multi-frame, as shown below. You can move to other images in the series by selecting them from the drop-down list.

Changing Image Series Status
As a curator, you may need to change the status of one or more images or image series. You can change the status of one or more selected images or image series individually or as a batch update.
Before you can change the status of an image or image series, you must use the QC Tool to find it. You must then select the image or image series you want to change.
Status options include:
QC Status | Description |
|---|---|
Not Yet Reviewed | This status (selected by default) is automatically assigned to an image upon submission to the NBIA database. |
Visible | All images in the series are visible. |
Not Visible | No images in the series are visible. |
To Be Deleted | Selected image series are to be deleted from the system. |
| First Review to Seventh | A configurable user-defined stage in the workflow of an image series. |
| Downloadable | Test the visibility of images in the series. This allows for downloading when set. It also separates the test cases from released cases. |
If you change the status of an image series, the change is also reflected in any shared lists to which the image series belongs. If you attempt to change the status of an image series that is in a shared list, an alert message appears, detailing to which shared lists the selected image series belong(s).
To change image series status
- Select Admin > Perform QC. The QC Tool page appears.
Scroll down to the QC Images by Series section. The images you selected in the Classic search or Dynamic search appear in the table.
