DEXIS DEXcam 3 and 4 Camera Setup Guide

This guide describes the installation and setup of the DEXIS DEXcam 3 or 4 intraoral camera for use with Dentrix Ascend Imaging.

Overview

Dentrix Ascend Imaging supports the acquisition of intraoral images from the DEXIS DEXcam 3 or 4 camera on a computer running the Windows operating system.

Note: Prior to the installation of the camera, the acquisition agent application must be installed on each computer that will acquire images. Refer to Setting up the acquisition agent for instructions on downloading and installing the acquisition agent.

Installation

Drivers for the DEXIS DEXcam 3 or 4 camera must be installed on each computer that the camera will be plugged into.

Note: If a DEXIS DEXcam 3 or 4 camera was installed and operating previously with this computer, and you plug the camera into a USB port, Windows will not search for drivers because they are already installed; in this case, you can ignore these installation instructions and skip directly to the "Testing" section of this guide.

To install the drivers, do the following:

1. Plug the DEXcam 3 or 4 camera into a USB port of the computer.

   The device will be detected, and Windows will start searching for drivers and then install them.

   Note: The drivers for DEXcam3 and DEXcam4 are available through the Windows Update service, so the computer must have internet access.

2. To prevent technical issues in the future, connect the camera to every USB port on the computer. This is to ensure that the device will be recognized no matter which port it is plugged into.

Testing

The DEXcam3 or DEXcam4 camera should now be functional in the Imaging module.

1. In the Imaging Procedures list, select 2D Oral/Facial Photo Images.

   

2. On the Acquisition Method for this imaging exam menu, select DEXcam 3 / DEXcam 4.

   

3. Click Proceed with Acquisition.

   

   A live video stream from your camera appears.

   

   Notes:

   • If a message about the browser not being able to access the camera appears, refer to the steps in the "Troubleshooting" section of this guide.

     

   • To access basic camera settings, click the cog icon (in the upper-right corner of the snapshot panel).

     

     
     
     

   Note: If your computer has a built-in webcam, Google Chrome may choose it by default.

4. If there is more than one camera connected to the computer, or if the computer has a built-in webcam, Google Chrome may not select the intraoral camera by default. If this happens, to select the correct camera, do the following:

   1. Click the camera icon (in the upper-right corner of the snapshot panel).

      

   2. Select the option that corresponds to the correct camera, and then click Change Source.

      

      Note: You may need to be restart the browser for the changes to take effect.

5. After you have configured the camera and started an acquisition, a live video stream from your camera appears.

   

   With the camera properly positioned, use the button on your camera to pause or freeze the live video stream (or click Pause Streaming).

   

6. Use the button on your camera to capture the current video frame (or click Take a snapshot). The resulting image is added to the snapshot panel, and the video stream automatically becomes live again.

   

7. Repeat steps 5-6 as needed to acquire additional snapshots.

8. On the snapshot panel, clear the check box of the snapshots that you do not want to save.

   

9. Click Assign Images.

10. Do any of the following:

    • To save one or more snapshots as intraoral images and assign tooth numbers, select the snapshots that pertain to the same teeth (deselect snapshots that do not pertain to the same teeth), and then drag them to the Select Teeth, UR/UL/LR/LL, Upper Jaw, or Lower Jaw box.

      

      If you drag snapshots to the Select Teeth box, select the applicable teeth, and then click Assign Teeth.

      

    • To save one or more snapshots as extraoral images, select the snapshots that are extraoral images (deselect snapshots that are not extraoral images), and then drag them to the Extraoral Photos box.

      

    • To save the snapshots on the snapshot panel as intraoral images, but not assign tooth numbers, leave those snapshots on the snapshot panel.

    Assigned intraoral images appear on the left side of the preview area; extraoral on the right.

    

    Note: If you have a mix of intraoral and extraoral images, they map to one procedure (D0350), which will appear in the progress notes with two icons. Also, you can delete or reassign the intraoral or extraoral exam as needed in the future.

11. Click Begin Uploading.
