Questions About Searching for Images:

How do I search images?

The NBIA software enables you to search for images in The Cancer Imaging Archive's local in vivo image repository.  See Chapter 2 of the TCIA User's Guide for more detailed instructions.

What if my image search comes up empty?

You must use caution not to create such a restrictive query that the search returns no results.  Our recommendation is you start with one criterion and add more one at a time to refine your search.

How do I manage and view images in my data basket?

As you review search results in The Cancer Imaging Archive, you can add items at any level to your data basket for subsequent download.  See Chapter 3 of the TCIA User's Guide for detailed instructions.

After you launch a search, the Search Criteria page displays the search criteria summary for your review. It allows you to save the query for future use.  See Chapter 2 of the TCIA User's Guide for more information.

What if I have a question pertaining to creating, editing or searching a shared list?

Anyone can create a shared list. Once you do so, you will need to record the exact name of the shared list to distribute to others who may want to use the list. That is the only way they can access it.  See Chapter 3 of the TCIA User's Guide for more information.

How do I search for images showing a particular disease?

The collection descriptions provide the best source of information about what disease was studied.  On the search-images page, scroll down to the Collections block, and click on the question-mark to the left of the collection name.  Click to see a brief description of the collection, usually with pointers to a site where more detailed information about the collection is available. 

Questions About Downloading Images:

How do I download images in JPEG, TIFF, BMP rather than DICOM format?

The Download Manager permits only the downloading of DICOM images.
If you want to capture a large number of images, you should download in DICOM and then reference two different websites for assistance with utilities that will convert DICOM images to other formats.

If you wish to only download a handful of image: (1) In the NBIA application, choose a study and series, then Show Images; (2) right-click over the image and Save Picture As *.jpeg.

How do I download annotated image files?

The XML files are in the series folder since they are related to the images in that series.  You can best find the annotated files by viewing the list of files in a folder.   

What Java version is required for Download Manager?

Java version 6 or higher of the Java Runtime Environment (JRE) must be installed to be able to open the Download Manager. See Chapter 3 of the TCIA User's Guide for more information.

What if I receive an error from Download Manager or Download Manager hangs?

The number of series that can be downloaded using Download Manager is dependent on several factors. Average image size, RAM on your computer and Java limitations all factor into how much you can download. If you experience issues or errors associated with the download you will need to reduce the number of series in your basket and try again.

I am behind a proxy server, will Download Manager work?

Accessing The Cancer Imaging Archive's Download Manager directly through a proxy server is currently not supported. If your only access to the Internet is through a proxy server, then our current recommendation is to ask your IT Department to allow your workstation to bypass the proxy server for direct access to

Java may be configured to utilize proxy settings; however, the developers of NBIA have not tested whether Download Manager correctly handles such settings.

1. A screen capture of the error message.
