Indicators overview

Indicators are displayed in the viewports to provide feedback on the state of the image.

Flip and Rotate

Rotate 90°

Rotated 90° indicator

Shown in the viewport to indicate that the image has been rotated 90°.

Rotate 180°

Rotated 180° indicator

Shown in the viewport to indicate that the image has been rotated 180°.

Flip

Flipped indicator

Shown in the viewport to indicate that the image has been flipped.

Cloned series

Cloned series indicator

Shown in the viewport and on the thumbnail of a cloned series.

Curved MPR

CMPR Control Point Limit

CMPR Control Point Limit indicator

The curved MPR has reached the 20 control point maximum.

Invalid Zoom

Invalid Zoom indicator

This indicator is displayed when the curve is too small to be rendered within the boundaries of the current viewport.

Fusion

Limited Measurements

Limited Measurements indicator

Shown in the viewport to indicate that not all measurement types are available for the series. Click the for more information.

Partial Volume

Partial Volume indicator

Shown in the viewport to indicate that the complete 3D volume cannot be rendered. A partial volume occurs when the original 2D data does not provide contiguous 2D slices.

SUV not available

SUV not available indicator

Shown in the viewport to indicate that there is not sufficient data to perform SUV measurements. Click the for more information.

Image error

Image error indicator

Shown in the viewport to indicate that there was an issue loading the image from the data source. Click More information to see additional information about the loading error.

Image loading

Image loading indicator

Shown in the viewport to indicate that data is being loaded.

Caution

When you load an image or zoom further into an image, eUnity will typically need to load more data. Once loaded, the indicator will disappear. If the indicator is visible, you must wait for the full data to be loaded.

Image sharpening

Image Sharpening indicator

Shown in the viewport to indicate that image sharpening is applied.

Key Images

Key image indicator

Shown in the viewport to indicate that it is a key image.

Source image indicator

Shown in the viewport on the source image from which a key image was created. The number represents the number of derived key images.

Unsaved key image indicator

Shown in the viewport on a manually created, unsaved key image.

Unsaved auto-generated key image indicator

Shown in the viewport on an automatically generated, unsaved key image.

Linking

Not linked

Shown in the viewport, a broken link indicator means that no matching slice could be found between the series. By default, the slices in linked series need to be within 5mm of each other to be considered for linking. If slices exceed the maximum threshold, the series will not be linked, and the broken link indicator will be displayed.

Series linked

Shown in the viewport, a link indicator means the series is successfully linked.

Link offset

Shown in the viewport, the link offset indicator means that the series' navigation has been manually offset from other linked series in the same study. That is, series linking was manually disengaged then the user navigated to a new point in the image stack and then relinked the series.

Offset not linked

Shown in the viewport, the offset broken link indicator displays when the series are no longer linked after a link offset is applied.

Lossy compression

Lossy 41:1

Lossy compression indicator

Shown in the viewport to identify the image data as lossy and summarize the compression ratio. Hover the cursor over the to display the following information: 

  • the type of image compression
  • the compression ratio
  • derivation description, if one exists

If the image has multiple compression types and ratios, the tooltip displays all known type / ratio combinations. If eUnity calculates that the compression type or ratio differs from the values already in the DICOM header, it will add an extra type / ratio combination below any others. For example: 

If eUnity adds this extra entry, it may indicate the image was compressed twice, or it may be that the compressor used a different formula than eUnity. eUnity calculates the LossyImageCompressionRatio tag as (Uncompressed-Pixel-Data-bytes)/(Compressed-Pixel-Data-bytes) whereas some compressors use (BitsStored / BitsAllocated)*(Uncompressed-Pixel-Data-Bytes)/(Compressed-Pixel-Data-bytes). Those compressors would report a ratio that is 3/4 of eUnity's ratio for an image with BitsStored = 12 and BitsAllocated = 16.

Lossy

Lossy compression indicator (reformatted and rendered views)

Caution

All reformatted and volume rendered views (MPR and 3D) are treated as lossy and will display a Lossy indicator in the upper-right corner of the viewport.

In MPR, 3D , and Fusion modes, hover the cursor over the to display the final JPEG render quality.

Mammography

CAD: Calc: 2 Mass: 1

CAD markers displayed

Shown in the viewport to indicate that CAD markers are displayed. The numbers represent the count for every type of displayed marker.

CAD: No Findings

No CAD findings

Shown in the viewport to indicate that CAD markers are NOT displayed. That is, CAD exists, but there are no findings to display for the image.

CAD: FAIL

Error with CAD information

Shown in the viewport to indicate that CAD markers are NOT displayed. That is, a fatal error with CAD information.

No CAD for Image

Image not related to CAD

Shown in the viewport to indicate that CAD markers are NOT displayed. That is, the image is not related to CAD.

No CAD for Study

No CAD in study

Shown in the viewport to indicate that CAD markers are NOT displayed. That is, there is no CAD in the study.

Case Score

Percentage of certainty of malignancy

The case score displays the algorithm's level of confidence, per study, that the study has malignant findings.

 

Name and version of CAD algorithm

If enabled, the name and version of the AI algorithm that is used for CAD objects is shown as part of the CAD overlay.

Quadrant View indicator

When in Quadrant View mode, this indicator is shown in the viewport on the non-breast wall side to indicate which quadrant of the breast is currently visible.

Related series indicator

In mammography studies, if the hanging protocol is set to Navigate Related Series, images of the same view type are stacked in the same viewport. This indicator is shown in the viewport to indicate how many images are stacked in the viewport and where you are in the stack.

System administrators can configure eUnity to include tomosynthesis images with the same view type in related series stacks.

Tomosynthesis indicator

Shown in the viewport for breast tomosynthesis studies to show the location of the current slice in relation to the other images in the series. The indicator shows directional markers to indicate whether you are scrolling in a caudal / cranial, or a medial / lateral direction. If CAD objects are available, the indicator will show additional lines to show which slices contains the CAD objects.

By default, the indicator shows caudal on the top and cranial on the bottom to reflect the acquisition order. If you prefer to have the indicator show cranial on top and caudal on the bottom, this can be configured by your system administrator. Note that the actual stack order is not changed when the indicator is flipped. The arrow of the tomosynthesis indicator will appear at the level of the first image of the tomosynthesis c-view series.

 

Multiphase Series

Multiphase indicator

Shown in the viewport for a multiphase series that has not yet been split into virtual series. The dividers represent the start and end of a phase. The arrow represents the slice position in the stack.

 

Partial Study

Partial Study

Shown in the viewport to indicate that the study is only partially downloaded and may not display all of its images. When you initially open a study that is in a partial state, you will also receive a Partial Study warning dialog that shows the Accession Number of the study that is in a partial state.

Presentation States

Presentation state applied indicator

Shown in the viewport to indicate that a presentation state is applied.

Red Free Filter

Red Free Filter indicator

Shown in the viewport to indicate that the red free filter is applied to the series.

Slice location

Slice location indicator

Shown in the viewport to show the current slice's position in the stack. This indicator can be enabled or disabled for different modalities by your system administrator.

 

Viewport capture

Unsaved viewport capture indicator

Shown in the viewport on an unsaved viewport capture.

Saved viewport capture indicator

Shown in the viewport on a saved viewport capture.
