This guide explains how to use the features on the Data Admin tab of the TCIA Radiology Portal. Curators use the Perform Quality Control feature to work with images that are not yet available to the public.

What's New in the Data Administration Tool (August 2021)

• A new dynamic search feature was added that allows the curator to create customizable queries.
• The performance and layout of the cine mode view have been improved.

Perform Quality Control

Understand QC Search Results

After you search for the series to QC, you can do the following on the search results page.

• View the image series in thumbnails, in the OHIF viewer, or in cine mode.
• Assign a new QC status to one or more image series in your search results.
• Generate a QC Status History report.
• Download QC data.

View Image Series

Your search results appear in a table at the top of the page. You can view a selected image series in thumbnails, in the OHIF viewer, or in cine mode. 

Viewing Thumbnails

In the View column, click the magnifying glass icon to view thumbnails of each image in the series.

Viewing in the OHIF Viewer

In the View column, click the movie camera icon  to view the series in the Open Health Imaging Foundation (OHIF) Viewer. 

Click to display the images in the series sequentially.

Note that ultrasound images can only be viewed as thumbnails or in cine mode.

Viewing in Cine Mode

In the view column, click the eye icon  to view the series in cine mode, which provides an animated slideshow of the images in the series. The DICOM tags are unique for each image in the series. Cine mode is available when the series has more than one image and DICOM tags are available for each image.

As soon as one series plays in cine mode, the first image in the next series loads immediately so that you can review series in sequence more easily.

Below the image are the image controls. You can enter an image number in the first box to view a specific image, or you can view the images in a series by pressing the play button, which is the single right arrow. Use the other arrows as follows.

The box on the right shows the frames per second, which is the speed in which the images progress during the animation. The default is 15 frames per second and you can enter another number in this box to change the speed.

Assign a New QC Status

As a curator, you may need to assign a new QC status of one or more images or image series. You can assign the status of one or more selected images or image series individually or as a batch update. 

1. Search for the series to QC. For example, search on Not Yet Reviewed to find series without a QC status.
2. Select the series for which you want to assign the status by clicking the box to the left of its row in the search results. You can select more than one if you want to apply the same change to each series you select. To select all series for the selected collection(s), click the box in the top left.
   
3. In the New Status section, select the status options you want to apply to this series. Refer to the descriptions of the search filters. 
   
4. Enter text into the change log box to track why you made the change.  This text will be part of the QC Status History Report that you can generate to track changes in visibility.
5. Click .

Change QC Status

You can also change the QC status of one or more images or image series. 

1. Search for the series to QC. 
2. View the series in cine mode.
3. In the Change QC Status section, select the status options you want to apply to this series. Refer to the descriptions of the search filters. 
   
4. Enter text into the change log box to track why you made the change.  This text will be part of the QC Status History Report that you can generate to track changes in visibility.
5. To save the update and move to the next series, click . Or to skip this series without making an update and move to the next series, click .

Generate a QC Status History Report

To view the status change log, search for the series you want to appear in the report, click the box to the left of that/those series, and then click .

The QC Status History report appears, displaying all changes that have been made to the status of the series you selected.

Download QC Data

A file appears in your browser that you can download to your computer.

Approve Deletions

TCIA role required to use this feature: NCIA.SUPER_CURATOR

For more information about roles, see Creating a New NBIA User.

This function is part of a two-tier deletion process. A super-curator can approve the deletion of image series that have been identified as "To be deleted" in the Perform Quality Control tool. After you approve an image series for deletion, you can either wait for the next scheduled system-wide deletion job or you can immediately remove image series that are approved for deletion.

To approve series deletions, follow these steps. Prior to approving deletions, you must assign the QC status of "To be deleted" to one or more series in the Perform Quality Control tool.

1. Click Admin > Approve Deletions.
   The Approve Deletions page appears.

2. Select filters to help you locate the series you have previously marked for deletion. Options for doing this follow.

   Criteria	Description
   Collection	You can only search on one collection (site) at a time.
   Released	Limit your search to image series that have either been released or not. Click Ignore not to consider Released status at all in your search.
   Batch Number	In the Batch Number box, enter the batch number of the images/series you want to find.
   Confirmed as Complete	Select Yes to search for a set of images/series that has been confirmed as complete, No to search for a set of images/series that is ongoing, or No Change to not consider this field when searching.
   Subject ID	Separate multiple Subject IDs with commas and then select  to perform the search.
   Most Recent Submission	In the From and To boxes, enter the most recent series submission date range by selecting a date in the calendar or by using the format mm/dd/yyyy.

   Using your filter selections, TCIA searches for image series that you have marked for deletion and refreshes the page to show those series. You may have to scroll both horizontally and vertically to view all series information and options.

   

   Expand the table to see more rows. To do so, scroll horizontally until you see the two diagonal lines in the lower-right corner. Click and drag that corner until the table expands to your desired height.

   
   

3. Select the box in the row of the series you want to delete. You may select more than one.
4. Optionally, add text to the change log to explain why you are deleting the series. This text appears in your QC Status History Report.

5. Click to approve the deletion. 

Image series you approve for deletion are still visible in the system and identified as "To Be Deleted". They are removed from the system at a system-configured time, such as at midnight (called an "offline deletion"), unless you perform a manual deletion (called an "online deletion").

Perform Online Deletions

TCIA role required to use this feature: NCIA.DELETE_ADMIN

For more information about roles, see Creating a New NBIA User.

This function is part of a two-tier deletion process. Using the Online Deletion feature, an administrator can delete image series that have been approved for deletion. This immediately removes images that are approved for deletion, rather than requiring the administrator to wait for the next scheduled system-wide deletion job.

Before you can use the Online Deletion feature, you must first approve image series for deletion.

To manually delete series, follow these steps:

1. Click Admin > Perform Online Deletion.
   A list of image series that have been approved for deletion appears.
   
   
   

2. Click to delete the series immediately.

   All series listed in this page are deleted. You cannot select one series on the page for online deletion and not the others.
