Endodontic Operatory Imaging Setup: Microscope Video, Sensors and CBCT Scans, and Where Each File Should Land

Operatory 3 is doing a retreatment. The assistant presses capture on the microscope, and the still goes to the camera's own USB stick. In operatory 1 the same button puts the image straight into the patient's chart. Down the hall, last month's CBCT volumes sit on the scan PC's D: drive.

This guide belongs to our endodontic office technology guide. It is written for the owner or office manager who has to sort this out with whoever looks after the computers. If you are weighing outside help, our dental IT support page explains how Legend works with practices. Below you will find a stack map, a capture-path decision table, a per-room spec sheet, a four-point backup audit, a CBCT integration table and a storage worksheet. Each vendor fact comes with its source and the date we checked it.

What is in an endo operatory imaging stack?

An endo imaging stack has six layers: the microscope camera, a capture device or PC, the 2D sensor, the CBCT unit with its acquisition PC, the practice software's image store, and the backup. Problems come from the handoffs between layers. So the useful map shows where each file is created, where it should end up, and who fixes each layer.

Fill in this table for your own office, one row per device. It takes ten minutes, and it becomes the inventory for the rollout checklist further down. For the rest of the office, see our IT services for endodontic offices page.

TDO's own knowledge base says the practice software "does not support any of these peripherals". A device has to work outside TDO before it will work inside it (TDO KB 329, January 27, 2026). That is why the last column matters: each layer has its own owner, and the gaps sit between them.

How do you get a dental microscope camera into the patient chart?

A microscope image reaches the chart in one of three ways: the camera records to its own USB media and someone imports it; an HDMI feed goes through a capture device to a folder the practice software watches; or the microscope archives to a network share or over DICOM. A watched folder on backed-up storage is the easiest to repeat in every room.

The three capture paths (plus the vendor app)

• • Camera records to its own media. ZEISS lists "Integrated camera with recording on USB; HDMI output" for the EXTARO 300 Essential camera option (ZEISS specification page, read October 26, 2026). The file lives on the stick until someone imports it.
• • HDMI to a capture device, then a watched folder. Global Surgical describes its 4K and 1080 HD cameras as "HDMI direct-to-monitor" video cameras. It sells a Magewell Image Capture Kit to "archive files from your microscope's camera to a computer during an exam" (Global Surgical, read October 26, 2026). Magewell's USB Capture HDMI 4K Plus lists a USB 3.0 host interface (USB 2.0 compatible), capture up to 3840×2160p30 or 1920×1080p90, and one HDMI loop-through. The loop-through keeps the operatory monitor live while the PC captures.
• • Network archive or DICOM. The EXTARO 300 Complete camera lists "network integration available for archiving purposes", and ZEISS lists DICOM as a package option or add-on depending on configuration.
• • Vendor app or cloud. ZEISS Connect (iPad) and ZEISS Surgical Cloud ("synchronize recorded images and videos") are add-ons. If you use one, ask the vendor where the data is stored and how it reaches your chart.

If you run TDO Software: Folder Monitor, TWAIN or DSLR Remote Pro

TDO's Folder Monitor "will allow TDO to automatically save Digital Images into the Patient's record", and it is "Only supported for JPEG files" (TDO KB 321, May 20, 2026). Set it up per operatory like this:

1. 1. Set the camera or capture software to save JPEG stills to one folder.
2. 1. In TDO 12, open Setup > Site Configuration > Edit Control Table, then the Workstation settings tab.
3. 1. Under Remote Camera, choose Folder Monitor.
4. 1. Point the Remote Camera Software Path at the capture folder.
5. 1. Tick Autosave Camera Image if images should save into the record automatically.
6. 1. For a ZEISS camera, add FolderMonitorMaxAttempts=200 to tdo.ini. TDO says "The Zeiss camera requires" this, and the setting works on TDO 11.340a or later.
7. 1. On TDO 12.400 or later, decide on Auto Archive (moves images to an Archive folder after saving) and Include Subfolders (for camera software that makes dated subfolders).

TDO's IT setup checklist lists two other routes. Microscope and intraoral cameras can use DSLR Remote Pro or the Folder Monitor. A webcam "can be accessed as a video driver, via TWAIN, or by using the Folder Monitor" (TDO KB 821, October 2, 2023). DSLR Remote Pro works only with Canon cameras, and a camera cord longer than 15 feet needs a booster cable (TDO KB 66, January 19, 2026).

If you run Open Dental

Open Dental captures from a live feed in the Imaging module (click Video). Its manual says "Any webcam or intraoral camera should be compatible", and Video needs an active registration key. Where a capture is saved follows a chain: the mount if you capture onto one, then "Default Image Category for video capture", then the Default Image Category, then the selected category. So set the video-capture category in Preferences on every operatory PC. The manual also says "Video Capture is not available for Open Dental Cloud", which matters before any cloud move. Open Dental is one of the practice management systems whose IT environment Legend supports; see our Open Dental IT support page.

If you run PBS Endo or another system

We found no public PBS Endo document on microscope capture (checked October 2026). Ask the vendor's support team which of the three paths above it accepts and which folder it watches, then set every room the same way.

Why does microscope video lag, and how do you fix it?

Microscope video usually lags when the live view runs through the PC instead of straight to the monitor, when the capture device sits on a slow USB port, or when power saving sleeps the USB port. Keep the monitor on the HDMI loop-through, capture over USB 3.0, and switch off USB power management.

Points 4 to 7 are TDO's published requirements. Points 1 to 3 and 8 are general practice, and your camera vendor's guidance comes first if it differs.

What should each endo operatory computer have?

Each operatory PC should meet the practice software's workstation spec, use a wired connection, avoid Snapdragon and ARM processors (TDO does not support them), keep a free USB 3.0 port for capture, and carry a name no other computer in the practice uses. The CBCT viewing or acquisition PC follows the CBCT vendor's spec.

Windows 10 reached end of support on October 14, 2025 (Microsoft Lifecycle). If any operatory or scan-room PC still runs it, our post on Windows 10 end of life for dental practices covers the options. Before any Windows 11 upgrade on a PC connected to a Carestream device, TDO asks you to check the device's compatibility first (TDO KB 792). How many network drops each room needs, and where the CBCT PC sits in a new build, are covered in our guide to technology for an endodontic office build-out.

Where are your CBCT scans saved, and are they in the backup?

CBCT volumes are saved in the CBCT maker's volume folder, not in the practice software's database. In TDO's Carestream integration that folder is the Kodak Volume Path, which in many offices is a second drive on the acquisition PC. The volumes are backed up only if that exact folder is in a backup job. TDO Cloud Backup excludes CBCTs.

What is the Kodak Volume Path?

In TDO's Carestream CBCT integration, the Kodak Volume Path is "the location where your 3D scans are saved to after reconstruction". TDO's knowledge base adds: "In many offices this is a second internal hard drive on the Acquisition PC." Other offices save scans across the network on the server. TDO suggests naming the folder "TDO Volumes" (TDO KB 854, October 10, 2025). If that folder is not on the backup list, the volumes are not backed up.

The four-point "where are your scans?" audit

Do this with your IT person at the CBCT acquisition PC. Each check says what to look at and what counts as a fail.

TDO also lists a monthly Fire Drill among the IT professional's duties, to check that the administrative workstation can stand in as the server (TDO KB 125, February 23, 2026). The endodontic software guide explains who is responsible for the TDO backup and how the Fire Drill works.

J. Morita offices have one more line to check. The i-Dixel Ver. 2.4 instructions say "The backup processing is not set up at shipment." Images moved with i-Dixel's "data move" are not covered by its backup, and the PC has to be on at the scheduled backup time (J. Morita i-Dixel IFU, file dated August 21, 2024). Ask who set up i-Dixel's backup, when it runs, and where it writes.

If any of the four checks failed, a Free Dental IT Assessment gives you written findings and prioritized recommendations on your computers, software, network security, backups and performance.

Once the folders are in the backup, test that the backup actually restores: a copy you have never restored from is still an open question.

Which CBCT systems integrate with TDO Software?

TWAIN bridges connect 2D sensors (Schick, Gendex, Digora and others); they do not give CBCT functionality. For 3D, only Carestream, J. Morita and PreXion integrate with TDO. Any other maker "will not have any CBCT functionality in TDO even if they mention some sort of TWAIN integration" (TDO KB 333, March 31, 2026).

Carestream imaging (CS Imaging) is one of the imaging platforms whose IT environment Legend supports; see Carestream imaging IT support. For other imaging platforms see DEXIS IT support and Planmeca Romexis IT support.

J. Morita i-Dixel with TDO: what IT has to set up

TDO's J. Morita article (TDO KB 715, September 30, 2026) is unusually direct about the IT side. Work through it as a checklist:

What if you switch CBCT brands?

When an office changes CBCT makers, "the volumes from the older CBCT manufacturer may not open in TDO". TDO added multiple-CBCT configurations from build 12.295 so offices can open volumes from more than one maker (TDO KB 727, November 21, 2025). Before the old unit leaves, confirm its volume folder is backed up and that the old viewer is configured on at least one PC.

Do CBCT scans show at your other location?

Not through TDO. TDO says: "TDO does not synchronize CBCT scans between locations." If you want scans viewed across locations, "your IT will need to configure and maintain a third-party synchronization program" for the CBCT directories (TDO KB 727). It also asks that paths be consistent across the computers you configure. Whether a second office should have its own CBCT is a build-out decision; see our guide to technology for an endodontic office build-out.

What about 2D sensors?

TDO lists Carestream 6100/6200 and XDR sensors as direct integrations. Schick, Optime, ScanX, Digora, DentiMax and Gendex connect through TWAIN, and DEXIS through a bridge. TDO supports only the known and tested TWAIN interfaces ("currently only Schick and Optime"), and says it "will be up to your IT" to keep TWAIN drivers current (TDO KB 329). When the sensor software and the practice software stop talking, our guide to troubleshooting dental imaging integrations walks through the checks.

How much storage does an endo practice need for CBCT and microscope video?

Work it out from your own files. Measure the average size of one volume in your CBCT folder and of a one-minute microscope clip, multiply by your weekly counts and weeks open, add scans you receive from other offices, then multiply by the number of backup copies you keep. Published sizes vary too much by unit and settings to use instead.

Measure first. Right-click one patient's folder in the volume path and open Properties to see its size. Do this for five recent scans and take the average. Record a one-minute test clip at your usual capture setting and check its size the same way.

Line E is easy to forget. An AAE Communiqué asks endodontists to consider "explaining the significant differences between CBCT imaging acquisition protocols" to referring dentists. It notes that patients increasingly bring CBCTs from other offices on CDs and jump drives, and says endodontists should tell referring dentists and patients that "a second scan at the endodontic practice will likely be acquired" (AAE Communiqué, Bruno Azevedo, April 1, 2022). So an office can end up storing both the scan that came in and the one it takes itself. For Carestream CBCT in TDO, KB 871 describes how a scan from a disc is copied into the patient's volume folder and linked with TDO's CBCT Syncer (November 21, 2025). That also means the scan lands in the folder your audit checks.

Worked example (example only; your numbers will differ). As an example input, Vatech America's export table lists 482 MB for a 5×5 field of view at 0.08 voxel without a viewer (829 MB with one); its table runs from 260 MB to 1,100 MB across fields of view (Vatech exports, by FOV; undated PDF). Ten such scans a week for 48 weeks is 10 × 482 MB × 48 ≈ 231 GB a year of CBCT alone. With two backup copies, that is about 463 GB of backup capacity, before video, stills and inbound scans. Put your measured figures in place of these.

How large a file is when you send it to a referring dentist, and how to send it, is a separate question from storage and is not covered here. For where backup copies should live and how they are protected, see our guide to dental backup solutions and our backup protection page.

Microscope video, USB sticks and patient privacy

Removable media moves patient images in both directions: capture sticks that leave the operatory, and CBCT discs and drives that arrive from other offices. These are practical questions to settle with your team and your IT person. They are not a legal reading; take questions about how a rule applies to your practice to your compliance lead or counsel.

For the safeguards side, see our HIPAA compliance services page and our summary of HIPAA Security Rule updates for dental practices. For sending clips, see email security for dental offices.

One configuration in every room: the rollout checklist

Once you know where every file goes, make each room match. Work through these steps one operatory at a time, starting with the room that captures most.

What to ask your IT provider

The bottom line

Choose one capture path per device and set every room the same way. Know where each CBCT volume folder is and put it in a backup job of its own. Check drivers against the vendor's list before any update. If you want a second pair of eyes on your operatories and scan room, ask for a Free Dental IT Assessment. It gives you written findings and prioritized recommendations on your computers, software, network security, backups and performance. Our endo practice IT support page covers the network, backups and accounts around it.
