This guide provides an overview of the Cancer Imaging Archive hosted by Washington University in St. Louis. It explains how to use the National Biomedical Imaging Archive (NBIA) software to search for and downloading images. The source of most of the instructions in this guide is the November 16, 2010 NBIA 5.0 User's Guide produced by the National Cancer Institute, Center for Biomedical Informatics and Information Technology.
The intended audience for this guide are researchers including pathologists and radiologists at cancer centers, CAD developers, academia, and industry that access the Cancer Imaging Archive through commonly available web browser software.
The guide discusses the following topics:
Chapter 1 Getting Started provides an introduction to the Cancer Imaging Archive and describes how to access the Cancer Imaging Archive.
Chapter 2 Searching for Images describes how to search the local and any selected remote image databases.
Chapter 3 Viewing Search Results describes how to review results from the Cancer Imaging Archive database searches

Cancer Imaging Archive provides the cancer research and medical community, industry, and academia access to imaging archives that can be used for many purposes, including the potential to assist in the development and validation of analytical software tools supporting these functions:
The archive provides access to imaging resources that improve the use of imaging in today's cancer research and practice by increasing the efficiency and reproducibility of imaging cancer detection and diagnosis, leveraging imaging to provide an objective assessment of therapeutic response, and ultimately enabling the development of imaging resources that will lead to improved clinical decision support.
Clinical trials, physicians and other researchers submit images to the Cancer Imaging Archive using the CTP (Clinical Trial Processing) software. Any potential user may then access the Cancer Imaging Archive to search for and download images and associated annotation files.
Images are stored in the medical image standard, Digital Imaging and Communications in Medicine (DICOM). A DICOM file stores the digital image along with a series of tags that contain metadata about the image such as patient ID, study ID, patient weight, anatomic site, and so forth. For more information about DICOM, see http://medical.nema.org.

A remote search site is an image database residing outside of the local Cancer Imaging Archive imaging archive. When you select a remote image database, Simple, Advanced, and Annotation Keyword Search pages display search results for the local Cancer Imaging Archive imaging archive AND any selected remote sites.
To select remote search sites, follow these steps:
1. Initiate the search by following one of these options:
OR
2. The Available panel shows the name of the remote node. The name used is the research center display name from the service metadata (acquired from the grid index service). As you mouse over the available sites, a popup displays where the site resides, for example "local" or a URL to the service. Select the remote site(s) that you want to search.
Note: By default, if you make no node selection, only the local node is searched.
3. Click the Lookup Search Terms link
The search criteria: modality, anatomic site, convolution kernel, collection, and equipment are populated based upon what actually exists in the searchable nodes. These criteria do not distinguish which comes from where (in the main UI) but Lookup Search Terms breaks this down so you will avoid searching for modality X that isn't available on node Y.
4. Continue defining search criteria as described in Performing a Simple Search or Performing an Advanced Search.
Note: Once retrieved, you can download remote node data using the Download Manager and the Download All button in the data basket. For more information, see Managing the Data Basket.
