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.
How do I search, download images and find out additional information about the collections - step-by-step ?
Let's begin by using the the modality of MR as an example to download MRI images of the Prostate, follow the steps below:
1. Log into TCIA.
2. Click on the Search Images link.
3. If you want to download all the MRI prostate images then select under Image Modality(ies) MR, under Anatomical Site, select Prostate and click on Submit.
4. Click on the "CHECK ALL" button to select them all. Once you have selected the series that you wish to download and click the "Add To Basket" button. This puts all the series from every page in the basket. For determining collection that the images go to, when you select the MR and Prostate and the system does the search, the collection ID will show up along with the subject ID.
5. Select "View My Basket".
6. On the next page, you do not need to check any boxes unless you wish to remove a series from your basket. In that case, you would select the box and then click on the "Remove Selected Items" button at the top.
7. Click on the Download Manager link.
If you would need to reference the corresponding wiki pages for any particular collection. In the Collection area, mouse over and click on the “question mark” which will return information on each collection. If there is a wiki available for the collection, click on it.
OR You can find additional information pertaining to image data from the TCIA home page > http://www.cancerimagingarchive.net/
In the middle of the page, under For Researchers, click on the link titled The Image Collections which will direct you to our Public Wiki. This wiki pages is organized into purpose-built Collections.
A collection of studies typically includes studies from several subjects (patients). In some collections, there may be only one study per subject. In other collections, subjects may have been followed over time, in which case there will be multiple studies per subject. The subjects typically have in common a particular disease and/or particular anatomical site (prostate, lung, brain, etc.)
The table on the wiki contains a list of collections available on The Cancer Imaging Archive. Each link in the table contains information concerning the scientific value of a collection, as well as additional meta-data where available from the data providers.
Under the Completed and Ongoing Collections table, you can sort any of the columns. For example if you are looking for MRI images of the Prostate, you could sort by Anatomical Sites which will bring all MRIs of the Prostate to the top of the list.
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.
What if I have a question on my query history or saving queries?
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 the websites below for assistance with utilities that will convert DICOM images to other formats.
If you wish to only download a single image (or a handful of images - one at a time): (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 https://public.cancerimagingarchive.net/ncia
Java may be configured to utilize proxy settings; however, the developers of NBIA have not tested whether Download Manager correctly handles such settings.
What if I am unable to download images through download manager and receive an error message in the status bar?
In order for our support team to perform additional troubleshooting, the following information is needed:
1. A screen capture of the error message.
2. A screen capture of the Java console (you may need to enable viewing the Java console using the Control Panel > Java Control Panel > Advanced > Settings: Java Console > Show Console.
3. Operating system and version.
- Windows XP: Start > Control Panel > System > General tab.
- Windows 7: Start > Control Panel > System and Security > System.
4. Browser and version.
- Internet Explorer: From the menu bar, select Help > About Internet Explorer.
