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.

Download a 14-day trial now of Easy DICOM Viewer and easily convert your images to DICOM files with the tag values you require.

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

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
