This chapter describes how to search the local and any selected remote image databases for images.
Topics in this chapter include:
Performing Searches
NBIA enables you to search for images in the local NBIA in vivo image repository. If available, you can also search remote imaging archives.
NBIA is designed to perform the following tasks:
- Search for images in simple or advanced search mode
- Combine search criteria defined in those searches with keyword searches of curated annotation data
- Save the search queries to be used repeatedly
- Review query histories
As subjects, studies, series or images are located, save them to your data basket for download.
Downloading series with annotation files
When you download a series that has annotation files (indicated by Yes in the Contains Annotations column), they are automatically downloaded as well.
NBIA submissions are organized in the following hierarchy, which is important to remember in creating your search query and reviewing search results:
Collection > Patient (Subject) > Study > Series > Images |
---|
NBIA provides three search modes:
Performing a Simple Search
Performing a Text Search
To perform a text search
On the NBIA home page, click Text Search or Search Images > Text Search.
The Text Search page appears.- Select the number of search results per page the search will return.
- In the box at the top of the page, enter a text string.
Use Lucene conventions for wildcards. Do not use colons as NBIA automatically filters them from the criteria. Lucene designates colons as fields. Since the text search searches all fields, colons are not necessary. Click Submit.
The search results appear.
