Converting Micro-CT TIFF images to DICOM files

We recently had a user who needed to convert Micro-CT scans consisting of TIFF images to DICOM files.  Easy DICOM Viewer could already convert most graphic files to DICOM, so we thought it would not be a problem.  Turned out to be a big problem.

Usability

First up was the usability issue.  Micro-CT scans are high-resolution images, running into hundreds to thousands of files.  In the original conversion screen, you had to drag the images you wanted to convert onto the DICOM image frames window.

This worked fine if you only had less than a hundred images or so, or when you needed to combine images from different folders.  However, for Micro-CT images, having to show a preview for hundreds or thousands of images was simply not feasible.  Thus, we removed the need to have to display the images in the frames window.  You can now start the conversion in the image browser window itself.

In addition, the image browser now lists the files by file names by default, which makes this screen more responsive.  You can of course still toggle between thumbnails and file names modes.

Also, if you now dropped a large number of files on to the DICOM image frames window, Easy DICOM Viewer will ask you to confirm that you want to proceed with the action.

With all the above changes, you can now easily convert Micro-CT scans into DICOM images very much faster compared to the previous version of Easy DICOM Viewer.

DICOM image properties

The main change here was to add the compression options for the converted DICOM images.  This allowed the user to generate smaller DICOM files, depending on their needs.

Other changes we made was to easily resize images by percentage, and also to convert the images to 16-bit grayscale.

With all the above improvements, you can now easily convert Micro-CT TIFF images to a single, smaller DICOM file.  Download a 14-day trial of Easy DICOM Viewer now and give it a try.

Presenter mode in Easy DICOM Viewer

In Easy DICOM Viewer 4.1, we introduced a presenter mode to help you share images in presentations and zoom meetings while maintaining confidentiality of your images.

Anonymized tag values

In presenter mode,  sensitive tag values are automatically anonymized.  For e.g. in the image list, you would usually see the patient name:

In presenter mode, this is replaced by a generic label:

In the image itself, information profiles like these:

are replaced with anonymized values:

In the tags listing, these values are also anonymized.

Highlighted cursor position

In presenter mode, the cursor position is highlighted so that your audience can track your cursor position easily.

Customizing presenter mode

You can customize the presenter mode settings to fit your requirements.  For e.g. you may want to anonymize additional tags, or customize the appearance of the cursor highlight.

Setting the presenter mode

Turn presenter mode on by selecting the Presenter mode option from the Application item on the tool bar.

Summary

Easy DICOM Viewer‘s presenter mode allows you to present/screen share images easily without worrying about exposing confidential information.  Your images are unchanged – only the displayed values are modified.  This is a huge time saving over the previous practice where you had to anonymize the tag values before using them in any presentations.

How Easy DICOM Viewer is different

Easy DICOM Viewer is a DICOM imaging application co-developed by LISIT, Co., Ltd., a medical software company based in Tokyo, Japan and Yohz Software.

What sets Easy DICOM Viewer apart from the many other DICOM viewers out there?  In this post, we’ll describe the more interesting features and how it benefits you.

Customizable layouts

You can display your DICOM images in a grid with equal sized cells e.g. in a 2 x 2 grid

or in irregular sized cells e.g.

You can define your own layouts, save them, and recall them instantly when you need them.

Custom defined DICOM details

Like most DICOM viewers, Easy DICOM Viewer can display the DICOM tag values embedded in your images.  Unlike most other viewers, you can define exactly which tags you want to display. 

You can then save these tag ‘profiles’, and display them in your images depending on your needs.

Orthogonal measurements

Polygonal measurements in Easy DICOM Viewer include the long axis and short axis values.  This provides you with extra measures to improve diagnosis.

Measuring an area of similar color

This borrows a technique from image editors.  If you have an irregular shaped area that is of a similar color, you can easily measure that area by simply clicking in the center of that area.

Easy DICOM Viewer will create a polygon of that area of interest for you, instead of you having to manually plot each time of the polygon.

Magnifying an area of interest

Instead of enlarging the entire image, you can choose to magnify only the area of interest.  This lets you concentrate your diagnosis on a specific area while still retaining a context of the overall region.

Anonymize/modify DICOM tag values

You can define tag templates to anonymize/erase/modify groups of DICOM tags, and apply these templates to easily modify the existing values in your DICOM images.  This saves you time from having to repeatedly enter the same values each time you want to modify the tags.

View DICOM tags

Easy DICOM Viewer displays the tag values for all opened images in a spreadsheet-like layout.  This allows you to compare the values of different images easily.

You can also filter the displayed values, helping you to view only the tags you are interested in.

You can export the tag values to Excel when you need to share or work with the values in a different application.  This saves you time from having to copy the values manually, which is prone to errors.

Presenter mode to easily share images

In presenter mode, you can open any of your images and Easy DICOM Viewer will automatically anonymize all sensitive tag values that are displayed in your images.   The DICOM tag values are not modified in any way.  It is only the displayed values that are changed.

This means you no longer need to manually anonymize your images first before using them in a presentation or online screen sharing session, saving you time.

Redact parts of your DICOM images

Easy DICOM Viewer includes a redaction function to black out areas of the image that may be confidential.  You can then export the images with the applied redaction to share with other users.

Convert images to DICOM images

You may sometimes receive medical images that are in a bitmap, jpeg, or png formats, and you need to convert them to DICOM images so that they can be archived in your PACS system.  Easy DICOM Viewer can perform the conversion for you, and at the same time use the tag templates described above to provide some basic values in the new DICOM images.

Burn images to CD/DVD

You can burn the images you are currently studying to a CD/DVD using Easy DICOM Viewer.  The CD/DVD will contain an integrated viewer so your patients can easily open the images themselves without having to download another viewer.  You can also display your company logo/branding within the viewer.

Burning images to CD/DVD using Easy DICOM Viewer

Easy DICOM Viewer adds the ability to burn your DICOM images to a CD or DVD.  You access this function using the Tools menu item.

If you have a workspace opened, Easy DICOM Viewer gives you the option to use images from that workspace.  You can also just choose other images on your computer.

A lite version of Easy DICOM Viewer is included on the CD/DVD containing your DICOM images.  When started, this viewer will automatically load and display the images that are found on the CD/DVD.

You can choose to display your company logo/brand when the viewer starts up.  Simply select the image to display, and for how long the image should be displayed.

Easy DICOM Viewer then prepares the disc image.  Once prepared, you can then click on the Test button to simulate how the viewer will display your logo (if selected) and how it displays your images.

You can also add additional files into the disc image if required.  Click on the Open folder button to open the staging folder, and copy the required files into that folder and sub-folders.

Next, simply provide the media to write the disc image to, and you’re once.

Using layouts in Easy DICOM Viewer 4

Easy DICOM Viewer 4 uses a new grid-based layout which offers more flexibility when it comes to displaying your DICOM images.

You can now easily display your DICOM images in a grid using the number of rows and columns that you require:

The above example creates a grid containing 2 rows and 2 columns.

You can then save this layout simply by entering a name for it, and clicking on the Save button e.g.

You can then recall the layout in the future whenever you need to use it.

You can also create layouts with cells than span across multiple rows and columns e.g.

You merge columns and rows by clicking on the Modify layout button and selecting the Merge column and Merge row items.

You can then save these unique layouts and apply them whenever the need arises.
