Release Notes

ProKnow DS v1.8.0 (5dec1df)

May 16, 2019

What's New

  • It is now possible to create a new structure based on a uniform margin of an existing structure. Please refer to the Editing Structures support article for more information on adding structures.
  • We've improved the patient list and patient checklist view so that they may support a large number of patients.
  • We've added the ability for the user interface to remember the selected patient scorecard from the patient page (until you switch to another patient).
  • We've updated the Clear All Slices button to provide support for different clear operations. These include "Clear all," "Clear every other slice," and "Clear specific slices." Please refer to the Editing Structures support article for more information on clearing slices.
  • We've also improved patient lists within the collections module to support selecting multiple patients from a list and performing batch actions.
  • Checkpoints at the beginning of a checklist will now trigger a workflow change to their transition state when one or more tasks within the checklists have been marked as Started, Done, or Exception. Previously, checkpoints at the beginning of a checklist would be triggered immediately regardless of the states of any following tasks.
  • You can now visit our support center by clicking on the ProKnow icon and then the Help & Support Center link or by holding Control (Windows) or Command (Mac) and clicking the Support button from the main navigation toolbar on the left.

Bug Fixes

  • Fixed an issue that could cause the interface to lock up when the support widget was activated.
  • Fixed an issue where Loading DVH Data indicator was shown even when a dose was not associated with a structure set.

ProKnow DS v1.7.0 (29c48ff)

April 26, 2019

What's New

  • It is now possible to simultaneously view image sets that were not exported in the same DICOM frame of reference by unlocking them from the Patient Images tab. It is now also possible to permanently force a consistent frame of reference between the active entities from the Patient Browse tab. Please refer to the Multiple Image Set Display (Images Tab) and Patient — Browse support articles for a complete description of the available options.
  • We've improved the table component used to display lists of patients (and collections) to allow sorting by column (by clicking on the table column headers) as well as to allow right clicking on a patient's ID in order to easily open the patient in a new tab.
  • We've completely overhauled our online self-help knowledge base (available at https://support.proknow.com) to be easier to navigate and more user friendly. In addition, we've replaced the support widget within ProKnow DS. This new support widget should be both more helpful (relevant articles should now be suggested based on your current location within the application) and less error prone (the support widget should now work properly within all browsers).

Bug Fixes

  • Fixed an issue that could cause structure sets that contained point ROIs to fail while committing updates.
  • Addressed several issues that could cause uploads or DVHs to fail to process in certain rare circumstances.
  • Fixed an issue that could cause image sets to be improperly activated when dragging a structure set from one active image set to another when multiple image sets are active.
  • Fixed an annoying bug that could cause dialogs to close unexpectedly when clicking on a dialog and then dragging outside of the form.
  • Fixed several minor issues related to patients that contained no entities being counted improperly when added to a collection.

ProKnow DS v1.6.0 (2dafe68)

March 25, 2019

What's New

  • Implemented the ability to move and copy patients between workspaces.

February 25, 2019

Bug Fixes

  • Fixed two rare situations that could cause failures during DVH calculation.

ProKnow DS v1.5.0 (f6c3947)

February 23, 2019

What's New

  • We've introduced a new top-level navigation item: "Workflows," which allows you to quickly browse and interact with patient checklists within their respective workflows. This new view summarizes relevant information about each patient checklist (such as how many tasks are contained in a checklist and who the tasks are assigned to) as well as allows filtering by common criteria. This is just the first version of this tool, so stay tuned for additional enhancements in the near future (for instance, the ability to perform more complex filtering such as "show me all patient checklists assigned to me").
  • Patient name comparisons are now more intelligent when uploading files, conflicts should no longer be reported when the patient names are semantically equivalent (e.g., "Smith^John" and "Smith^John^^").
  • Improve the default labels for patient objects in the Patient Browse tab.
  • We've selected a more appropriate mouse cursor for the "Zoom to Selection" tool in the Patient Visualizer.

Bug Fixes

  • Fixed an issue that could cause DVH analysis to fail in some rare situations.

ProKnow DS v1.4.0 (bebc484)

January 17, 2019

What's New

  • It is now possible to customize the patient orientation used when viewing patient images and other objects. A commonly requested feature, this allows you to indicate whether you want to view the patient from the planning orientation (if a plan is present), as well as whether you wish to always view images from the feet (i.e., always head first). This setting is accessible from the "Your Profile" dialog. Please refer to the Managing Personal Preferences section of the Configuring Your Profile support article for a complete description of the available options.
  • Implemented "Zoom to Selection" and "Zoom to Fit" visualizer tools. Please refer to the Patient Viewer Toolset support article for complete details.
  • Improved the contouring interpolation tool in situations where multiple contours are present on adjacent slices. Please refer to the Editing Structures support article for complete details.
  • Implemented API routes for directly downloading CT, plan, and dose DICOM files. This allows users of the API or Python SDK to directly access the DICOM files without having to utilize the batch download process.
  • Improved patient name anonymization.
  • It is now possible to select multiple scatterplot items at once by clicking and dragging a selection window around the points of interest.
  • Added number of patients to labels in scatterplot legend.
  • Improved accessibility of scatterplots by implementing varied symbols and improving default color palette.
  • Improved default colors assigned to new structures created in ProKnow DS.
  • Simplified adding patients to collections (from within the patient) by removing extraneous confirmation dialogs.
  • It is now possible to add an organization collection to one or more workspaces when the collection is being created.

Bug Fixes

  • Fixed several issues related to contouring lock renewal timeouts and associated issues that could arise if you continued contouring once the "Are you still contouring?" dialog had appeared. This should resolve the "Provided tag does not match current tag for ROI" message that would occasionally appear when committing a structure set.
  • Fixed issue that could cause some RT Ion Plans to fail to process during upload due to unsupported Primary Dosimeter Unit value.
  • Added support for CyberKnife dose files that do not contain a Referenced RT Plan Sequence.
  • Fixed transparency of image set styling at the edge of the window/level range.
  • Users with email addresses containing capital letters should now be able to be updated or deleted.
  • Fixed several minor usability and styling issues.

ProKnow DS v1.3.0 (e1c73c1)

December 19, 2018

What's New

  • Implemented the ability to create patient checklists, which are sets of tasks and checkpoints that can assist in managing effort within the patient workflow via the new Patient Checklists sidebar. Patient checklists can be used for keeping track of any arbitrary tasks associated with the patient, regardless of whether they will be performed within ProKnow DS. In addition, it is possible to define patient checklist templates and custom checklist workflows within your organization in order to drive towards consistency and simply the process of creating patient checklists.
  • Improved default entity visibility when new entities are being uploaded. New entities that are children of the current primary entity will now activate automatically.
  • Improved the name of downloaded patient archive files.
  • Added the date each patient was created and the number of objects contained within the patient to the patients list.

Bug Fixes

  • Line probe no longer displays ancillary image set data when plotting (i.e., it only displays values for the primary image set).
  • Patient download modal no longer lists empty studies.
  • Fixed several issues related to tooltips.

ProKnow DS v1.2.0 (324d56d)

November 10, 2018

What's New

  • Implemented the ability to simultaneously view multiple image sets located in the same coordinate system (i.e., when they have been resampled in the same coordinate system prior to uploading to ProKnow DS). Use the new Patient Images sidebar to activate multiple image sets.
  • Implemented the ability to attach arbitrary files (e.g., PDFs, images, and videos) to patients via the Patient Documents sidebar. This can be used to keep track of non-DICOM documents (e.g., pathology reports) associated with the patient.
  • Implemented the ability to both temporarily remove protected health information (e.g., patient names and medical record numbers) and explicitly prevent certain users from viewing this information via the new "View PHI" role permission. Use the "Anonymized Mode" toggle from the main ProKnow dropdown menu to temporarily anonymize patient information (useful when showing a colleague a patient without exposing medical information).
  • Implemented ability to create a new structure as an intersection of two other structures.
  • Implemented the ability to independently control whether users can download DICOM files via the new "Download DICOM" role permission.
  • It is now possible to add a commit label and message when committing a new version of a structure set (it is also possible to edit labels and messages once committed).
  • We now record and display the name of the user user that performed relevant updates to structure set version (created, last updated, committed).
  • It is now possible to delete old structure set versions (please note you may not delete the currently active version).
  • Added appropriate "Add item" buttons to the top of list-based user interface pages (so you no longer need to scroll to the bottom of the list to add a new item).
  • Added a patient filter on the Browse tab within a Collection.
  • It is now possible to display gridlines on DVH graphs.

  • When downloading DICOM files from a patient, the modal will now default to having the currently active entities selected.
  • For organizations with many workspaces and collections, the corresponding dropdowns will now display as many items as will fit on the screen (as opposed to a limited number).
  • Improved isoband rendering (layers that are turned off will now fill with the color of the next layer, instead of appearing as a transparent gap in the dose).
  • Added relevant tooltips to the Edit Objectives modal.
