The image viewer

The image viewer in the center area displays the image your select in the file browser. There are 2 types of images - single frame images and multi-frame images. Multi-frame images are indicated by a filmstrip icon on the image thumbnail. When you select a multi-frame image, the individual frames are displayed along the top of the image viewer. Select a multi-frame image from the list of images in the file browser. Click on any of the individual frames along the top, and you will find that the main image changes to display the selected frame.

Using the magnifier

To use the magnifier, click on the Use magnifier mode button. In the main image window, a new layer magnifying the underlying area is displayed. Try moving the magnified area by clicking anywhere in the rectangle and moving the mouse. You can also resize the magnified area by dragging on the yellow handles. To exit the magnifier mode, click on the Use view mode button.

Information profiles

Information profiles display selected DICOM tag values on the 4 corners of the image. You can create your own information profiles to display the values you want to display. To create or modify information profiles, click on the Application > Preferences item on the main menu. The Information profiles tab displays the existing information profiles and the values they display. You can add, edit, and delete profiles here, and also modify the DICOM tag values to display in the 4 corners. Let’s create a new profile. Click on the Add profile button. Enter a name for the profile. DICOM Search creates your new profile, and fills in the tag information with default values. Let’s say we want to display the patient weight in the top left corner. Click on the View tags button. This brings up the FIelds and Tags window. Enter weight in the filter area. We can see that the tag value for Patient’s weight is [00101030]. This is the value we enter in the top left window. Note that the tag value is enclosed in square brackets, and the entire line is enclosed in angled brackets. DICOM Search will now display the patient’s weight value (if available in our images) when we select the Tutorial profile profile. Supposing we wanted to display some text to provide some context to the value that’s displayed, we just have to add the text before or after the tag value e.g. To use the information profile in the image viewer, right click anywhere on the image to bring up the context menu. Select the profile you want to use under the Information profile item.

Multi-frame image playback

You can play back the sequence of images using the playback control buttons at the bottom of the image viewer. You can also choose the delay between each frame. When you step through individual frames, DICOM Search applies a fade-in fade-out transition so that you can easily compare the 2 frames. You can also set the delay to make the transition faster or slower. Try clicking on the Next frame or Previous frame buttons now to see this transition. Each of our images contain a wealth of information, stored in the DICOM tags, so we will look at the tag viewer next.
