Version 2 changes
Incompatibility with version 1
Version 2 of DICOM Search introduces changes that makes
it incompatible with libraries created using version 1. You
will need to reindex your DICOM images in order to store the
private tags in addition to the public tags.
To continue using the libraries created in version 1, rename
the existing DICOM Search 1 application folder before
installing version 2, in order to have both versions available
depending on which libraries you want to access.
You can download the last release of version 1 using this link
if required.
All tag values are now indexed
Version 2 indexes all public and private tags. Sequences are
also indexed. For e.g. the column
0020,9222-3-0020,9167
stores the Functional Group Pointer (0020,9167) value for the
3rd element of the top-level Dimension Index Sequence
(0020,9222).
Additional tables used
Because there is a limit to the number of columns that can
be stored in the underlying database, the tag values are
now spread across 3 tables:
•
images
•
seq52009230
•
seq2005140f
The tags view remains the primary source to run queries on,
as it joins the images and thumbnails tables into a single
easy-to-use view, The seq52009230 and seq2005140f
tables are used to store sequence values for the (5200,9230)
and (2005,140F) tags respectively.
For e.g. if you run the following query to retrieve values from
the seq52009230 table:
The ds_imageID column is the key column that links back to
the images table (or tags view). The ds_sequence value is
the top level sequence number for the 5200,9230 tag. So
the fully qualified tag for the first column (2005,140F)-1-
(2005,1455) in the above example is 5200,9230-1-2005,140F-
1-2005,1455. The fully qualified tag for the second row for
the same column is 5200,9230-2-2005,140F-1-2005,1455,
and so forth.
This gives users immense flexibility in searching for DICOM
tag values. If in the future we find there are other top level
sequence tags that can cause us to hit the maximum
columns limit, we will store those sequence tags into their
own tables too.
Copied files can be renamed using tags
When copying files from the search results, you can now
use tags to rename the files. For e.g. you could include the
physican name (0008,0090) as part of the file name:
You can use multiple tags, aliases in place of tags, and even
use tags as part of the folder name (DICOM Search will
create the folders where necessary) e.g.
DA, TM, and DT tag types are now stored as numbers
In version 1, these tag types were stored as SQLite date time
data types. This required users to remember to use the
DATE, TIME, and DATETIME functions to convert the values.
In version 2, the values for these tag types are stored as
numbers as per the DICOM specification. This makes it
easier for users who were used to working with these values.
For DT tag values where the timezone information is
included, you’ll need to use the EXTRACTNUMBER function
to remove the timezone values.
Depending on user feedback, we may add more functions
to make working with date and time values easier.
You can now convert images containing multiple frames
In version 1, when converting images to png, jpg, gif, or bmp,
only the first frame was extracted. In version 2, you can now
choose to extract and convert all the frames.
Sequence tags now display total and index
The tags view now display the total number of items for
sequences that contain more than a snigle item, and each
sequence item is displayed beneath an index level. This
makes it easier to know which sequence index you are
viewing a particular tag for, especially when the tags are
filtered based on your search criteria.
The same structure is used when exporting the tags to
Excel files.
