Frequently asked questions
Frequently asked questions
General
Is VET-PLAN Ortho a substitute for surgical training?
No. The app is a planning aid for surgeons and clinicians who already have orthopaedic training. It helps with accurate measurement and visualisation; surgical decisions and execution remain yours.
What image formats can I use?
JPEG, PNG, and DICOM-extracted images. Higher-resolution images give more precise measurements but use slightly more memory.
Where are my cases stored?
In the cloud, tied to your account. They sync automatically. Radiograph images are stored separately in cloud storage and load on first open of each case in a session.
Does the app work offline?
No. Cases sync to the cloud and radiograph images stream from cloud storage. An internet connection is required.
Calibration
Why does every radiograph need its own calibration?
Radiographic magnification varies between exposures. The same bone projects at slightly different sizes on different shots. Calibrating per-image is what makes the rest of the app’s measurements accurate.
What if I don’t have a calibration marker in my radiograph?
You can’t calibrate without one. The app will refuse to unlock measurements and template placement until a scale is set. This is intentional — a measurement without calibration is worse than no measurement, because it looks authoritative while being wrong.
Can I use a coin or other improvised reference?
Yes, as long as you know its real-world diameter and set that as the reference size before placing. The default is 25 mm (a typical radiopaque sphere). Other sizes are configurable in the calibration sub-panel.
Templates
Are the implants the right size?
Yes, as long as the radiograph is properly calibrated. Template dimensions reflect manufacturer specifications.
What if a template’s dimensions look wrong?
First check the calibration. If that’s correct, report the template via the help icon — it’s almost certainly a library data issue rather than a calibration issue.
Can I add a template that isn’t in the library?
Not directly from the app interface. Template additions are handled administratively. Send a request via the help icon with the manufacturer’s specifications.
How do I delete a placed template?
Select it and press Delete or Backspace, or use the trash icon in the swap panel.
Why does my placed implant rotate when I rotate the X-ray?
By design. Implants are anchored to the bone, not to the screen. Rotating the radiograph for viewing rotates everything attached to it — implants, measurements, overlays — so the implant stays in the correct position relative to the anatomy regardless of viewing angle.
Sharing
Do recipients of a shared link need an account?
No. The link itself grants read-only access. Recipients don’t need to sign up or log in.
Can I revoke a shared link?
Yes. From the Referrals modal (top bar), click revoke on any link. Revocation is immediate.
Can recipients edit the case?
No. Shared access is read-only. Recipients see exactly what you’ve placed and measured, but can’t modify it.
Performance
Why are templates slow on first session?
The template library prefetches in the background after the app loads. Within a few seconds of opening, all templates are cached and subsequent placements are instant. If you place a template before prefetch completes, the first one may take an extra moment.
Why does the gallery feel sluggish on first open?
Radiograph thumbnails decode on first open. After the first session they’re cached and load instantly. If the gallery is consistently slow, report it via the help icon with your browser and OS.
Collaboration
Can multiple people work on the same case at the same time?
Not in real time. The app uses last-write-wins for now — if two people edit the same case simultaneously, the last save overwrites the earlier one. Real-time collaboration is on the roadmap.
How do I see who changed what?
There’s no edit history view yet. The Referrals modal shows when each link was created and by whom, but per-edit history isn’t surfaced. If you need this for clinical record-keeping, contact us — it’s a known gap.
