How to send a CBCT scan to a specialist
A CBCT volume is the file most likely to defeat email — a few hundred megabytes to a couple of gigabytes, in a format most inboxes reject outright. Here is how to get one to a specialist in about a minute.
Step by step
Export the volume from your imaging software
Export as DICOM (a folder of .dcm files) or the viewer bundle your system produces. If you are unsure where that lives in Romexis, Sidexis or CS 3D, the export guide linked below walks each one.
Zip the folder
A CBCT export is a directory of hundreds of slices. Zip it so it travels as a single file and arrives in one piece.
Drop it in and add the specialist
Up to 10 GB per file. Enter the specialist’s email and set a 4-digit PIN.
Text them the PIN
The link goes by email, the PIN does not — that separation is what keeps a forwarded inbox from becoming a disclosure.

Common questions
How do I send a CBCT scan that is too large to email?
Email attachment limits are typically 20–25 MB, and a CBCT volume is routinely hundreds of megabytes to a couple of gigabytes, so it will not fit. Send handles up to 10 GB per file: the specialist receives a link rather than an attachment, so nothing has to squeeze through either mail server.
Does the specialist need an account to open it?
No. They click the link, enter the 4-digit PIN you gave them separately, and download. No account, no software, no app.
Is it HIPAA-compliant to send a CBCT this way?
The transfer is encrypted in transit and at rest, access needs a PIN sent over a separate channel, links expire automatically, and a BAA is included. That is a materially different posture from a plain email attachment, which is neither encrypted end to end nor covered by a BAA with most consumer mail providers.
What format should I send — DICOM or the viewer bundle?
DICOM is the safest default because any specialist can open it in their own software. Some systems also export a self-contained viewer bundle, which is convenient but ties the recipient to that vendor’s viewer. If you are unsure, send the DICOM.
How long does the specialist have to download it?
Links expire after 7 days by default, and you can revoke one at any time — files are deleted immediately when you do. You get a notification when the package is opened.
