ClearCanvas RIS/PACS v13.0 Personal Edition Release Notes

Updated September 8, 2014

The following is a list of some known incompatibilities, defects and warnings that may affect use of the software. Where applicable, workarounds and guidance is provided. A note on versioning: because the various ClearCanvas projects share certain common libraries, version numbers are shared among various products such that common libraries have sequential versioning from release to release. Consequently, the products do not necessarily have sequential version numbers.  For the most up-to-date release notes for this version of the software, follow the link below.

Known Incompatibilities

ID

Summary

Description

Component

792

Images don't display on grayscale monitors

The application does not support dynamic/static grayscale palettes on older Dome/Planar monitors/video cards. Images may appear blank or there may be rendering artifacts.  Thoroughly evaluate image quality with your display configuration to ensure that it is supported before deploying for clinical use.  Otherwise, newer display device(s) may be required.

Workstation

2920

Some controls appear black on some, usually older, Dome monitors

The application does not support all Dome monitors, particularly older models.  Thoroughly evaluate image quality with your display configuration to ensure that it is supported before deploying for clinical use.  Otherwise, newer display device(s) may be required.

Exception generated on running workstation from network

The workstation should be installed only on the local machine.

Workstation

8449

DICOM related settings are not migrated on upgrade

Some settings are not being migrated as of yet on upgrade. These settings include those in the sections ClearCanvas.Dicom.Network.NetworkSettings, ClearCanvas.Dicom.ServiceModel.Streaming.StreamingSettings, and ClearCanvas.Dicom.DicomSettings.

Known Bugs

ID

Summary

Description

Component

3914

Deleting log file while application is running causes strange behaviour

Only workaround is to stop the Workstation Shred Host Service, close the Workstation application, delete the log, then restart the service.

Workstation

4881

Workstation considers a pixel to be in an ROI if the top-left corner is contained in the region.

Pixels are only considered to be in a region of interest if the top left corner is included in the region drawn - i.e. pixels on the top and left edge of the region may be unexpectedly excluded and pixels on the bottom and right edges may be unexpectedly included. If precision down to the pixel is required for mean, standard deviation and/or SUV, draw the ROI to include or exclude the top left corner of the desired pixels. The probe tool can be used to determine where the top-left corner of a pixel is.

Workstation

5750

MPR fails to render 8 bit volumes

No workaround, but such data sets are very rare.

Workstation

6785

Opening study after display configuration change shows black workspace

If this problem occurs after changing monitor configuration, restart the application.

Workstation

7862

Does not render overlays from compressed images if overlay is embedded in pixel data

Images like this are not DICOM compliant.  Configure the modality to use the overlay repeating groups instead of embedding overlays in pixel data.

Workstation

8133

Reference lines are not captured in clipboard images

No workaround.

Workstation

8226

Media writer provides no progress during "Creating disc image" stage, which can take a very long time

This stage may take a long time, depending on the size of the images being written. Wait.

Workstation

8394

Key Image display sets with multiple study references always show a placeholder image for images from the "other" study

When you capture key images from more than one study in a session, all captured key images are added to a new KO series in all of the affected studies. It is arguable whether or not this is the correct way to do it, but the reason for doing it was to alert the user that key images were created in the same session for multiple studies regardless of which study was (later) opened.

However, when you open one or all of the affected studies (even via multi-selection), only key images from the study to which the key image display set belongs are shown; others are placeholder images.

Workstation

8819

Viewer will not print/export Fusion images

There is an issue with exporting and printing Fusion images - these operations may or may not complete successfully.

To workaround, toggle the colour bar overlay off before attempting to print or export. Alternatively, consider taking a screen capture.

Workstation

9252

Workstation does not properly support pixel padding value

No workaround. Images with pixel padding values may not display as the manufacturer of the modality intended.

Workstation

9449

The Easy Image Selection tool (Easel) can push the last study out of view when there are many related studies.

In Easel, if there are many related studies, it is possible that hovering over certain studies will "push" the last study out of view. When examining a list of studies in Easel, the user should use the scrollbar as a cue to whether there are more studies in the list.

Workstation

9852

Searching for accented characters requires an exact match

For example searching for "López" will not find "Lopez" and vice versa. This is not technically a defect, but the likelihood of inconsistent data is high and it makes searching more difficult. The workaround is to use the ? wildcard when searching for these potentially different characters.

Workstation

9975

"My Computer" can perform poorly when accessing folder containing many zip files

No workaround.

Workstation

11333

Workstation GUI appears incorrectly when Windows is configured to use 125%

The workaround is to change the setting back to 100% (96 DPI)

Workstation

11634

DICOM Editor is unusable for sufficiently large multiframe images

Workstation sometimes becomes unresponsive and crashes when opening a large multiframe image in the DICOM Editor.

Workstation

11639

Cannot copy a subset of frames in Enhanced MR/CT studies to the Clipboard

On an Enhanced CR or MR, Copy Range of Images to Clipboard does not allow user to select a range of images (frames)

Workaround: If copying individual frames is essential, consider having the modality resend the study using a non-Enhanced SOP class

Workstation

11658

Reference Lines on Enhanced CT/MR always show frame #1

Reference lines always say "1" (image number) on Enhanced CT/MR

Workstation

11732

Opening breast tomosynthesis images on the Portable Workstation is very slow and sluggish

Because of the size of the images, loading them from a CD is very slow.  Load time can be as much as 20 seconds per image.

Workstation, Portable Edition

12562

Cannot get Explorer back if you cancel out of closing Workstation

If you have unviewed layouts, close workstation but cancel out of the closing operation, Explorer will have been closed and you cannot get Explorer back.
