Radiographic/Tomographic Systems, Multidirectional

Definition : Radiographic/tomographic systems that use a pattern of x-ray tube movement (e.g., spiral, elliptical, circular) that provides blurring in both directions of the plane. These systems are mostly used to examine the lungs and other soft tissue having little natural contrast, particularly using narrow-angle tomography (i.e., zonography).

Advanced Search

There are 3 types of search. Please only use one option at a time.

1) Build a boolean search string.

Ensure that document matches include...

...all of these word(s):

...and optionally include these word(s):

...but do not have these word(s):

2) Search for a phrase:

Enter your phrase:

3) Search on part of a word:

Enter the first few characters of a word:

Information on how to use Search

There are 2 types of basic queries: Terms and Phrases.
A Term is a single word search.
A Phrase would wrap a string of words in quotes and find matches on the extact string.

Boolean Operators
You can combine basic queries with Boolean operators to form a more complex query. Boolean operators define the relationships between Terms or Phrases. Our search supports the following Boolean operators: AND, "+", OR, NOT and "-". Please note that Boolean operators must be all uppercase.

AND
example search: default AND document
This is the default operator. It will be used if there is no Boolean operator between two terms. For example: default document is the same as default AND document. In this case both terms need to exist within a listing to find a match on that listing.The + character is synonymous with using AND.

OR
example search: default OR document
In this case just one of the terms needs to exist within a listing to find a match on that listing.

NOT
example search: default NOT "document type"
The NOT operator excludes documents that contain the term (or phrase) after NOT. So a listing match would have to include the word default but not the phrase "document type". The - character is synonymous with using NOT.

Wildcard/Prefix queries
You can perform "wildcard" or "prefix" queries using the '*' operator. Whereas all of the previous search found exact matches on the whole term or phrase, a wildcard search will find partial matches.
example search: ehr*
This query will match all documents containing words beginning with the prefix 'ehr' like the word Ehrlichia.
