Creating contact sheets in Easy DICOM Viewer

In Easy DICOM Viewer 5, you can now create contact sheets from images containing multiple slices/frames.

Say we have a series containing 94 slices.

We want to export all 94 images into a single PNG file.  When we choose the Export Image action, we select the Create contact sheet option.

Once exported, our PNG file looks like this:

You have full control over how the images are rendered.  You define how many columns to use, the size of each image, the background color, and the footer value.

What exactly is the footer value?  It’s whatever value you want displayed at the bottom of each image.  It can be static text, which isn’t very useful, or it can be one or more DICOM tag values.

For e.g. let’s say we want to display the slice location at the bottom of each image.  The tag we want is 0020, 1041.  We simply enter this value as the footer value e.g.

When we now export the PNG contact sheet, the slice location is displayed on the bottom of each thumbnail.

We could of course add some label to the value.  Say we add the label Location: to the value e.g.

resulting in this:

Anonymization options in Easy DICOM Viewer

Easy DICOM Viewer can be used to anonymize DICOM tag values in your DICOM files.  There are 3 options you can select:

Anonymize basic patient information

This option anonymizes the most basic DICOM tags, which are the following:

  • patient’s name (0010, 0010)
  • patient ID (0010, 0020)
  • patient birth date (0010, 0030)
  • patient’s age (0010, 1010)
  • patient’s sex (0010, 0040)
  • comment (0010, 4000)
  • institution name (0008, 0080)
  • institution address (0008, 0081)
  • institution department (0008, 1040)
  • Issuer of Patient ID (0010, 0021)
  • study description (0008, 1030)
  • series description (0008, 103E)
  • operator’s name (0008, 1070)
  • referring physician’s name (0008, 0090)
  • physician(s) of record (0008, 1048)

Anonymize top level tags using NEMA specification

This option anonymizes tags using the recommendations outlined in this link – http://dicom.nema.org/dicom/2013/output/chtml/part15/chapter_E.html#table_E.1-1.

Compared to the basic anonymization option above, this option anonymizes a lot more details.

Apply tags template

This option lets you apply a tags template to the selected images.  A tags template is a set of changes you want to apply to the DICOM tags.  You can create multiple templates for different purposes e.g. one template to modify certain tags to a specific value, another template to erase only patient details, and yet another tag to modify all patient, doctor and study details.

The Preview window will then show you how the tag values would appear in the modified images.

These 3 options give you complete flexibility as to how you want to anonymize the DICOM tags in your images.
