Convert bitmaps to DICOM images

Using Easy DICOM Viewer, you can easily convert images (in bmp, jpg, png, gif, tif formats) to DICOM images.  To start the conversion, click on the Convert images tab in Easy DICOM Viewer.

Select your images from the file browser in the bottom pane, and drag and drop them into the upper pane.

You can reorder the frames in the DICOM image simply by dragging and dropping each image to their intended location.  To convert the images to DICOM images, click on the Create DICOM file button.

In the Save DICOM Image window, enter the DICOM image file name.  You can also choose to create a single DICOM file with multiple frames, or one DICOM file for each frame.

Click on the OK button to create the DICOM file.

You can also add DICOM tag values for the new DICOM files.

You can use the values from any tag templates you already have in Easy DICOM Viewer, to easily fill in the values.

Anonymizing and editing DICOM tags

You may sometimes want to modify the tag values in your DICOM images to maintain patient anonymity.  To do that in Easy DICOM Viewer, simply click on the Export series or images button

select the Anonymize top level tags option, and enter the value (ANONYMOUS by default) to replace the existing values.

The top level tags that are anonymized follows the recommendations outlined here (http://dicom.nema.org/dicom/2013/output/chtml/part15/chapter_E.html#table_E.1-1).

If you want more control over which tags are modified and with what values, you can use tag templates.  You can define one or more templates and use them whenever necessary.  The list of existing templates are listed in the drop down list when you select the Apply tags template option.

To create or edit templates, click on the Edit templates button.  In the Tag Templates window, you can define how the DICOM tags should be modified.  For more details, please see this link.

Among other actions, you can:

  • generate UUID-derived UID values for tags that require such values
  • reuse the same UID values for all images in the same series
  • use existing tag values as part of the new values
  • modify tags at all levels, not just at the top level
  • delete all private tags
  • delete all tags
  • view a preview of the values before and after applying your changes

Download a 14-day trial now of Easy DICOM Viewer and easily anonymize or modify your DICOM tag values.

Getting a sense of scale in your DICOM images

In Easy DICOM Viewer 3.1, we added the option to display a horizontal and vertical ruler in your DICOM images.  This helps to get a sense of scale when viewing the image, and also helps users make rough approximations.

To toggle the display of the ruler, click on the Show ruler button on the toolbar.

You can also choose to display the ruler in different units of measurement.  The active unit is displayed in the top left corner of the ruler.

You can also choose to display a grid overlay over the image together with the ruler.

To display this grid overlay, select the Show grid lines option in the Show ruler drop down menu.

Download a 14-day trial now of Easy DICOM Viewer and see how easy it is to display a ruler and grid in your DICOM images to help you measure regions of interest.

Easy PDF Search 5 – highlighting function

In Easy PDF Search 5 (EPS), we added a highlighting function.  This is to help users who need to highlight content in their PDF files after EPS has delivered the search results.  Previously, we had to open the PDF file in another application like Acrobat Reader to highlight the content, thus losing the search results and navigation functions available in EPS.

IMPORTANT NOTE

DON”T use the highlighting function in EPS to redact your PDF content.  The highlighted areas are path ‘objects’, which can be easily removed.  

Getting started

We will need to open the file we want to highlight in EPSs’ internal viewer.  To do that, select the Open PDF file using internal viewer option from the context menu in the search tree.

The file is then opened in its own tab.

The search words are still highlighted, but using outlines instead of a solid color.  Using a solid color is confusing as it becomes difficult to differentiate our own highlighted text and those highlighted by EPS for the search words.

You can still highlight the search terms in solid color by deselecting the Show outlines only for search words option.

Highlighting content

To highlight the content, or remove the highlighting, use these options on the toolbar.

Toggle the Highlight text button to enable and disable highlighting.  When enabled, drag the mouse over the content you want to highlight.  Release the mouse to apply the highlight.

TIP: You can also click on the right mouse button to toggle the Highlight text button.

The color drop down allows you to select the highlighting color.

Click on the Remove highlight button to remove existing highlighted areas.  When enabled, click on a highlighted area to remove the highlight.  Note that EPS is unable to differentiate between highlights applied in EPS and by other applications.  If it detects a path object on where you clicked on, it will simply attempt to remove it.

The Remove all highlights on current page button allows you to remove all highlighted areas on the current page.  Again, EPS cannot differentiate between highlights it applied and existing highlights applied by another application.  It will simply remove all PDF path objects it finds on the current page.

 

Saving the highlighted file

You must save the modified PDF file using a different name from the original file name.  Click on the Save PDF file button to save your modified file.

Once you have saved the file, the modified PDF file name is displayed in the drop down list under the Save button.

To open this file in an external viewer, click on the Open PDF file using external application button.  Windows will then attempt to open the file using the registered PDF application.

Your PDF file is also automatically saved when you close EPS, but you need to have previously saved the file.

Persistence

When you close and reopen EPS, any files that were previously opened in the internal viewer will also be automatically loaded and displayed.  This allows you to continue your work from where you last left off.

Next steps

Depending on user feedback and sales, the following items are currently considered for implementation:

  • an option to remove all highlights from the entire file
  • a function to extract all the highlighted text from a page/file
  • make the highlighting function available to files opened outside of the search function

If you have any other suggestions, please drop us a line at support@yohz.com.

Finding PDF files that do not contain any text

The situation is as follows: you use Easy PDF Search to index and search for words and phrases in your PDF files.  Suddenly, you realise that not all your files have been indexed because they actually do not contain any searchable text.

This can happen if your PDF files are actually scans of documents, and you use an OCR application to read and store the text inside the PDF.  Now you need a quick and easy way to identify those PDF files that have not been scanned.

You can easily do this in Easy PDF Explorer.  First, select the Count images and text option.

If you want an accurate count of the number of images and text, you can leave the option at in all pages.  If you just want to know if a file contains any characters, then selecting the but stop when text is found option will speed up the process significantly.

This is because Easy PDF Explorer no longer has to scan every page in the PDF file – the moment it encounters a page that contains text, it stops scanning.  If your aim is just to know which files don’t contain any text, then this option is the fastest.

Once you’ve selected those options, select the PDF files you want to scan in the explorer window.

Easy PDF Explorer then lists down the files together with the number of characters in each file.

Click on the Characters column, and you can quickly sort the files by number of characters found.

Say you want to copy those files with no text to another folder.  Right click and select the Deselect all item.

Now click on the first file with no text, and while holding down the SHIFT key, click on the last file with no text.  The range of files will be highlighted.

Now right click to bring up the context menu, and click on the Select item.  The range of files will then be selected.

Now just click on the Copy to folder button, select the folder to copy the selected files to, and you’re done.  Now all you have to do is run your OCR application on those files.

Download a 14-day trial of Easy PDF Explorer now to work with your PDF files faster.  Also give Easy PDF Search a try – probably the fastest way to search your PDF files for multiple words and/or phrases.

What’s new in Easy PDF Search 4

Easy PDF Search (EPS) 4 was recently released with the following changes:

Notes window

There is now a Notes window in EPS which you can use to take notes while working with your search results.  The Notes Editor is a simple text editor, and will float above all other EPS windows.

Your notes are saved in the rich-text format, and if you have Microsoft Word installed, you can also save the notes to DOCX and PDF formats.

You can also embed PDF documents into the Notes window, so you can view multiple PDF documents simultaneously for reference.

Usability improvements

  • You can now scroll across multiple pages by holding down the SHIFT key and moving the mouse wheel.
  • You can now zoom in and out of a page by holding down the CONTROL key and moving the mouse wheel.
  • You can now specify the font size to be used in the Search and Results windows via the Settings screen.

Database clean-up

Over time, the full-text index database may contain entries for non-existing files.  You can now delete those entries using the Clean function in the Settings screen.

This will free up space in the database for new files, but it will not reduce the size of the file.

For existing users who purchased a license within the last 12 months, you can upgrade to version 4 for free.  For users with older licenses, you can purchase a license extension for only USD 10.

You can download a 14-day trial version using this link.

Updating embedded data in OLE Object fields

Do you need to update a batch of OLE Object fields, and you don’t want to have to update them individually using your application?  Access OLE Import can help you with such tasks.

We had a user that needed to update a few thousand rows in an Access table, specifically an OLE Object field that stores a zip archive.  He already had all the zip files ready, but did not want to have to update each record individually.

So in SQL Image Viewer, the existing records show up as zip archives embedded in OLE Object packages:

The user already has the new zip files he wants to update the records with.  Using Access OLE Import, he just needs to prepare an upload definition file providing the key field value (ID in this case) and the OLE Object column to update the contents for (the quotations field).

In Access OLE Import, we enter the table to update together with this data file.

And that’s it.  Access OLE Import will update the OLE Object fields with the new zip files accordingly.

Note that you can also update any of the other text or numeric fields in your tables using Access OLE Import.  For e.g. if the user had wanted to update the address field, he only needed to enter the new values in the data file e.g.

Learn more about Access OLE Import here, or download a 14-day trial now.  Access OLE Import can help you update batches of records easily, instead of having to update each record individually via your application.

See here on how you can update linked file locations using Access OLE Import.

Updating linked file locations in OLE Object fields

Have you ever needed to update the linked file locations in an OLE Object-type field in your database?  Access OLE Import can do all that for you and more.

Let’s say you have a table with an OLE Object column that contains links to a file.  In SQL Image Viewer, you may see the following:

So all the images are currently linked to files located in the F:\Customer files\ folder.  What if the files are no longer there, for e.g. when you share your database with other users?  Your users will not be able to access the images because they may not have that folder available to store the images.

Access OLE Import can help you update the details in the OLE Object field.  To do that, you just need to provide the key field value of the records to update, and their corresponding file location, in an Excel file.  So for e.g. let’s say all our images are now stored in the G:\Employee photos\ folder.  Our Excel spreadsheet will simply contain the following:

The ID column refers to the ID field in our table.  The keynumber definition tells Access OLE Import that this is an integer key value.

The photo column refers to the photo field in our table, and filecontent tells Access OLE Import we want to work with the contents of the files listed in this column.

We then tell Access OLE Import that we want to create links to the files.

And that’s all there is to it.  Access OLE Import will update the relevant records, and the links to the images are updated accordingly.

If you prefer to embed the image in the table, then select the embedded option instead.

Now Access OLE Import will embed the images directly in the table.

See here for a more detailed example on how to update embedded OLE Object data.

Working with measurement labels in your DICOM images

In Easy DICOM Viewer, you can create multiple measurements in your DICOM image.  By default, only the label for the selected measurement is displayed, to make it obvious which measurement the label is referring to.

You can also choose to display all the measurement labels by selecting the Show all option on the Labels options.

However, in this example, our labels overlap each other.

To reposition a label, first select the Move, edit, delete item from the measurements context menu.

Then select the measurement area you want to reposition the label for.  Press CONTROL and click on the new label position.   Here, we have repositioned our 2 labels so that they no longer overlap when displayed simultaneously.

The measurements panel

All the measurements are also displayed on the measurements panel together with the measurement details.

You can also perform various actions like hiding all the measurements on the images, applying the various label options, or deleting one or more measurements.  You can also export details of your measurements to a Microsoft Word file.  Just click on the Export image and measurements to Word button and enter the file name.

The exported Word file is automatically opened by default.

Download a 14-day trial now of Easy DICOM Viewer and experience for yourself how easy it is to create, edit, and share measurements in your DICOM images.
