Easy DICOM Viewer – anonymizing tags with Japanese character values

In Easy DICOM Viewer, you can anonymize the DICOM tags in a series of images.

Prior to version 5.3, you could not modify the tag values to include Japanese characters.  From version 5.3 onwards, this is now possible.

For example, say you want to modify the Image Type tag (0008,0008) value to T1強調画像 (T1 weighted image).  First, create a new tags template or use an existing template.  A list of the most commonly used tags are displayed.

To check if Image Type is on the list, you can enter the tag value in the Filter area.

No results are displayed, meaning the tag isn’t on the list.  You could also have entered a partial description, e.g. type

A tag containing type is displayed, but it isn’t the tag we want.  To add a new tag, click on the Add button.

Enter the group and element value.

The new tag is then added to the list, and you can enter the value you want to use.

Another thing to note when using Japanese text is to ensure that your Specific Character Set tag (0008,0005) contains the value ISO 2022 IR 87.  You can check this in the Tags viewer in Easy DICOM Viewer.

If the image’s character set does not have this value, the tag value would be displayed  incorrectly.

With the correct value for Specific Character Set, the tag value is displayed correctly.

If you would like us to support additional character sets, please drop us a line at support@yohz.com.

Using date and time values in your file naming convention

In SQL Image Viewer, Access OLE Export, and SQL Blob Export, you can use date values in the file naming convention.

In this query, we select the ID (integer), content (blob), and lastupdated (datetime) fields.

To use the date value from the lastupdated field, include it in the file naming convention value.

The file name then uses the default format of yyyymmdd to format the date value.

You can also format the date value differently using date and time specifiers.  For e.g. using <LASTUPDATE:yyyy_mm> indicates that we only want to use the year and month elements separated by an underscore character.

resulting in

You can also use the time values e.g. hhnn indicates we want to use the hour and minute values:

resulting in this:

You can use both and and time values by using the appropriate specifiers.  The thing to note is that minute specifiers use n or nn, instead of m or mm, as those are month specifiers.

A list of all date and time specifiers available here for reference.


Multi-user PDF search

So you have a collection of thousands of PDF files.  You use Easy PDF Search to create a full text database that you use to search your PDF collection.  Now you want to allow other users to do the same.  What are your options?

Easy PDF Search Basic Edition allows up to 2 other users to search your PDF database, while the Standard Edition allows as many users as your machine can support.


On the machine where the Easy PDF Search full text database database was created, in the Connect to Database window, select the Local database item and also the Database will be shared via hotspot item.


Starting the hotspot – Basic Edition

Click on the Start hotspot button on the toolbar.

Enter the hotspot settings you want to apply.

When you click the Start button, the hotspot will be active.  On the toolbar, there is now a Stop hotspot button.


Starting the hotspot – Standard Edition

Similar to the Basic Edition, click on the Start hotspot button on the toolbar to open the hotspot settings window.

You can learn more about the various hotspot settings for the Standard Edition here.

In short, you can support more users on the Standard Edition, and each user can be assigned roles that limit their access to your PDF libraries.

Connecting to a hotspot

In the Connect to Database window, select the Easy PDF Search Server item, and enter the IP address and port of the machine where the hotspot is active.

If you are connecting to a hotspot running the Basic Edition, leave the Login value empty.  If you are connecting to a Standard Edition server, you need to enter the Login value.

Click on the Connect button to connect to the hotspot-enabled database.  You can now search the PDF files in that database.

Searching PDF files using word stemmers

Easy PDF Search by default searches for complete words/phrases in your PDF files.  For example, if we search for the word like, only files containing that exact word are returned and highlighted in the search results.

If we wanted to search for words starting with the word like, we can perform a prefix search using the * character e.g. like*

This returns all words with the prefix like.  Unrelated words (from a grammar perspective) like likelihood and likewise, will be returned, while a related noun like liking will not be returned.

Stemmed words

Stemming is the process of removing a part of a word, or reducing a word to its stem or root.  In the example above, the words like, likes, liking, liked, and likely all share the same root word i.e. like.

When we want Easy PDF Search to use stem words when searching e.g.

we need to first create a stem database, then search that stem database.

Creating a stem database

To create a stem database, click on the Options > Stemmer language > Settings item.

In the Stemmer Settings window, select up to 5 languages to create a stem database for.

You can create stem databases for the following 27 languages:

  • Armenian
  • Basque
  • Catalan
  • Danish
  • Dutch
  • English
  • Finnish
  • French
  • German
  • Greek
  • Hindi
  • Hungarian
  • Indonesian
  • Irish
  • Italian
  • Lithuanian
  • Nepali
  • Norwegian
  • Portuguese
  • Romanian
  • Russian
  • Serbian
  • Spanish
  • Swedish
  • Tamil
  • Turkish
  • Yiddish

When you want to search the stem database, select the stem language you want to search in from the Options menu.

Easy PDF Search then displays the stem language database that the search will be performed in.

In the search results, the stem database that was searched will also be displayed.

Testing the stemmers

To test which words stem to the same root word, you can use the test utility in the Stemmer Settings window.  Select the language you want to test, then click on the Test … stemmer tab.

Enter the search word, then a list of words you want to check if the root word matches the search word.

Next, click on the Test button.  Non-matches will be displayed in a strike-out manner.

Download a 14-day trial of Easy PDF Search now and experience how easy and fast it is to search your PDF files collection, now with the ability to perform stem word searches.

Using the bookmarks bar in Easy PDF Explorer

The Bookmarks bar in Easy PDF Explorer appears below the main menu in Easy PDF Explorer.

Using the Bookmarks bar

The bookmarks lets you quickly open a folder or file by clicking on the item on the Bookmarks bar.  To place an item, drag and drop the folder or file from the Explorer window to the Bookmarks bar.

For example, this is the visual representation when you drag a folder over the Bookmarks bar.

When you drop the item on the Bookmarks bar, a button is created to represent the folder.

When you now click on that button, the active Explorer window will open to that folder.

Similarly, when you drag a file item on to the Bookmarks bar, a button is created for that file.  In the image below, we have 2 file items – a PDF file and an Excel workbook.

When you click on the file name on the Bookmarks bar, the active Explorer window will open to the folder containing that file, and highlight the file name.

Opening the context menu for items on the Bookmarks bar

You can open the context menu associated with the folder or file item by right-double-clicking on the button in the Bookmarks bar.  The image below shows the context menu when we click on our Excel file item.

Rearranging items on the Bookmarks bar

Right click on the folder or file item, then drag and drop the item on its new position.

Removing items from the Bookmarks bar

Right click on the folder or file item and drag it away from the Bookmarks bar.


Extracting files from a Thomson Reuters FileCabinet CS database

We recently had a user that had to extract Word and Excel documents from a Thomson Reuters FileCabinet CS database using  SQL Blob Export.  The user was helpful enough to send us a couple of samples of the raw data stored in the table, allowing us to inspect the data in detail.

Turns out Thomson Reuters stores the files in a different manner to what SQL Blob Export expected, so we had to make some adjustments to the export process.

Beginning with version SQL Blob Export 6.1, you can now export items from your FileCabinet CS database.  The same feature is found in SQL Image Viewer.  When you run a query to return the items, it will be shown as OLE Structured Storage packages.

You can then export the files using the export wizards.

If you encounter a situation where SQL Blob Export or SQL Image Viewer is unable to export your files, please send us an email at support@yohz.com.

It would be very helpful to also attach a couple of samples of the rows that failed to be exported.  To extract the data exactly as stored in the database in SQL Blob Export, please do the following:

  • select the Extract bin files option on the Options page
  • once the export process has completed, you will find files with the .bin extension.  Please send us a couple of those files so that we may check how the data is stored in your database.


Filtering libraries in Easy PDF Search

In Easy PDF Search 7.4, you can now filter the list of displayed libraries.  Say we have the following category and library structure:

To display only the PostgreSQL related libraries, we enter postgresql in the Filter libraries area.

Partial searches are also possible e.g.

To filter on multiple values, enter each word separated by a space e.g.

In the above example, Easy PDF Search will display all libraries containing the words postgresql or arduino.

If you need to filter phrases, enclose the phrase in double quotes e.g.

In this case, only libraries containing the word postgresql admin or arduino are displayed.

Next, click on the Export all data button and select the Export to Excel option:

If you have multiple data sets, you can select which data set(s) you want to export.  In our example, we only have a single data set.

On the next page, enter the column containing the images if not already entered by SQL Image Viewer.

We then select how to display the images in the Excel worksheet.  You can display the images in the worksheet itself:

or as a link in the worksheet, where the images will be exported to disk and the link will open. those images:

or as both inline images and a link:
