2025

July 24, 2025v3.14.9Build release
  • Preserve existing Series Instance UIDs - do not overwrite them with randomly generated UIDs when pushing data to PACS.
July 2, 2025v3.14.8Build release
  • Change JPEG2000 decoder to WebAssembly.
June 30, 2025v3.14.7Build release
  • The form unlock button for Reader forms should be available only to Readers when the visit has status Pending Reader.
June 26, 2025v3.14.6Build release
  • Use a query parameter to pass the token, ensuring the URL remains concise and avoids exceeding length limitations.
June 24, 2025v3.14.5Build release
  • Fix to TemporalPositions and ContentTimeSorter logic: ensures MR and PT images with temporal positions are sorted by a sensible default, and prevents rotation errors when downscaling would result in zero-size images.
June 21, 2025v3.14.4Build release
  • Form editors with the Investigator role can now edit permitted forms from visits with status 0. If an open query exists, they can also edit forms from visits with status 1 or 2.
  • DICOM edit rules now skip fields with missing values instead of inserting empty strings. This prevents unintended blank values in DICOM tags when the referenced form field does not exist.
  • The export button for audit logs has been repositioned, allowing direct export of log data without loading the UI table.
June 11, 2025v3.14.3Build release
  • Persistent-disk staging for temporary files prevents “disk full” failures on large batches and makes DICOM import more resilient.
  • Temporal MR series now support echo-time variants, so dynamic sequences display correctly no matter which TE is acquired.
  • Basic visualisation of 4-D segmentation objects (SEG with multiple time points) lets you scroll through temporal image series alongside segmentation mask.
  • Password-reset flow modernised: instead of receiving a system-generated password, users now get a time-limited reset-link email.
  • Trial administrators can copy a user’s reset-link directly from the admin dashboard if the automatic email cannot be delivered.
  • Prod-environment testing can run automated validation suites behind the login server, enabling true end-to-end testing.
  • Calculated fields can now pull values from ParentField without also specifying VisitName, simplifying cross-visit report templates.
May 21, 2025v3.14.2Build release
  • Backend dicom import job finishes even when some images fail: after nine retry attempts it skips the unreadable objects, flags them as errors, and imports the rest.
  • Unsupported SOP Class UID is now visible for every rejected file.
  • Improve import speed.
  • Correct time-frame offset applied for some 4-D DICOMs, so temporal frames render in the right position.
  • Support for more DICOMs by adding more VRs to DICOM parser.
  • Full 8-/16-bit palette color with auto-scaling; previously unsupported palette-colour studies now show correct colours.
  • Image masks can be applied to several series in a single redaction action.
  • PrepareDownloadImageSet authorisation checks patient-level rights (not the imageSet ID), preventing unauthorised downloads.
  • Uploads via the UploadFileToPatientIDAndVisitName lacking an accepted file extension are rejected early with HTTP 400 Bad Request.
  • Also, endpoint returns HTTP 404 (unknown patient or visit) and HTTP 403 (unauthorised) instead of failing silently.
  • E-signature is required when using “Send back to QC 1” or “Notify investigator”.
  • Visit-submission emails now include the investigator as a recipient.
  • Unsubscribe from emails flow hardened: users must click an unsubscribe button rather than a single-click link.
  • Performance improvements to patient list.
  • Repository table columns resize correctly.
  • Investigator status bar shows yellow for visits with status: Pending Submission.
  • Calculated dropdowns can set their default value via logic.
  • Query list includes a query status column.
  • Audit-trail includes a user role column.
  • Skip hidden and errored imageSets and remove duplicate forms in DTF and QC Checklist reports to prevent null-reference errors.
  • Fix progress bar overlay for some users.
April 28, 2025v3.14.1Build release
  • Fix retrieval of DTF entries completed by investigators who no longer have access rights to SliceVault.
  • Fix the DICOM-tag export so it correctly embeds data from DTF forms, even when the completing investigator’s access has been revoked from SliceVault.
  • Re-introduce patient list filtering by Patient ID and Site Name.
April 15, 2025v3.14.0Minor release
  • A manual authentication step has been added to the electronic signature process. Users are now prompted to enter their password and select a reason when applying a signature, improving compliance with FDA 21 CFR Part 11 requirements.
  • New API endpoints have been introduced to support a wider range of GET and POST operations. These endpoints allow for secure data upload and download, and support dynamic data retrieval, improving system scalability and enabling more efficient data management.
  • The system’s de-identification process has been updated to meet the latest DICOM Standard 2025b requirements, ensuring continued compliance with evolving data protection protocols for medical imaging.
  • The email notification system has been updated. Monitors and Project Managers will now receive automatic alerts when new queries are posted, improving communication and response times within project teams.
April 1, 2025v3.13.3Build release
