Searching for Studies

Previous pageReturn to chapter overviewNext page

When querying the local store (My Studies) or an external DICOM server (My Servers), it is usually necessary to specify search criteria in order to narrow down the results. The following fields are available on the Vetstation DICOM Explorer:

Responsible Person 1
Search the responsible person's first and last name (this is usually the owner).  The search uses wildcards by adding a * to the beginning and end of the text you entered and will find all responsible person whose name contains the text anywhere in their full name.
Name
Search the patient's name.  The wildcard is added similar to the Responsible Person field.
Species 1
Search the patient's species. The search uses wildcards for these fields by appending a * automatically.  The value is used to search in the species description as well as the species code value/meaning if the species code is encoded in the image.  Species codes are those defined by the SNOMED Reference Terminology for designating species.
Breed 1
Enter a value for breed. The search uses wildcards for these fields by appending a * automatically.  The value is used to search in the breed description as well as the breed code value/meaning if the breed code is encoded in the image.  Breed codes are those defined by the SNOMED Reference Terminology for designating breeds.
Responsible Organization 1
Search by the name of the responsible organization. The search uses wildcards for these fields by adding a * before and after the search field automatically.
Patient ID
Accession #
Study Description
Enter the first n characters of the value to search for. The search uses wildcards for these fields by appending a * automatically.
Study Date (From ó To)
Enter a value for either or both of the From and To fields. The date range must be valid.
When neither field is populated, all dates are a match. Unspecified dates are also a match.
When the To field is empty, all dates after the From date (inclusive) are a match.
When the From field is empty, all dates before the To date (inclusive) are a match. Unspecified dates are also a match.
Referring Physician
Works the same as the Name field.
Modality
From the drop-list, select only those modalities you are interested in. Studies containing at least one series that is an exact match for any of the specified modalities is considered a match.
When no modalities are specified to search on, all modalities are considered a match.

 

Click Search to query for studies that match the criteria you have entered.

For brevity, the displayed results will display only one of the species description, species code meaning, or species code value, in descending order of preference.  The same is true of the breed fields.

 

 

Technical Note

Those already familiar with earlier versions of the Vetstation will notice that there is now only a single Name field.  This is to simplify name searching so that you can search on any part of the patient's name, refining your search as needed.  To search explicitly by last and first name, enter the text as LAST NAME, FIRST NAME providing as many characters as you need to find the correct patient.  For example, entering SMI, JO will search the same way the Vetstation previously did, finding all patients whose last name starts with SMI and whose first name starts with JO.  However, it is unlikely you will ever need to use the name search in this way.

There are a number of reasons for simplifying the name search, some of which are:

1.In DICOM, names are supposed to be delimited with a ^ character, but there is an abundance of poorly formatted DICOM data out there.  This makes searching by last and first name more difficult than it should be.
2.Makes searching non-English DICOM names much simpler, since there can actually be up to 3 full names, delimited by an = sign.
3.A user would normally search by Patient ID or Accession# when trying to find a particular patient, unless they are unknown. In this situation, when little is known about the patient (except, perhaps, parts of his/her name), "more is better".

1 Not all DICOM servers support the fields Responsible Person, Responsible Owner, Species and Breed.  The typical behaviour when a server does not support these fields is that the search will continue with any other criteria that you have specified.  Please consult the DICOM Conformance Statement of the other server to determine whether or not these fields are supported.
