  1. Creating a New Cast Order

Starting a New Order: Steps for initiating a new cast order.

4.1 Initiating a New Order

  • Starting the Process: To begin creating a new order, select the “Create New Order” button from the main menu.


  • Entering Patient Information: Follow the on-screen prompts to input details such as therapist name, patient’s personal information, and specifics about the fracture.

4.2 Option to Exit

  • If you need to exit during this process, tap the three dots in the upper right corner of the screen and choose “Exit and Delete Form.” A warning pop-up will appear to confirm that all entered details will be discarded. Confirming this will return you to the main menu.

4.3 Scanning Tutorial or Proceed to Scan

  • After filling in all necessary details, you’ll be presented with two options: watch a scanning tutorial for guidance or proceed directly to the scanning process.



4.4 Scanning Process

  • Positioning for Scan: Aim the camera at the patient’s extremity and adjust for the appearance of an AR 3D box on the screen.


  • Adjusting the AR 3D Box: Resize the box to encompass the extremity using a two-finger gesture.


  • Initiating the Scan: Press the ‘Scan’ button and begin moving around the object. The object will gradually fill with white color.


  • Pay attention to on-screen messages:

    • If “too close to the scene” appears, move slightly away from the object.

    • If “Please hold still so we can capture a keyframe” appears, hold the scanner steady until the message disappears.

  • Handling Lost Tracking: If tracking is lost and the object turns transparent white, adjust the camera angle until the object returns to solid white.

  • Completing the Scan: Once the object is fully covered in white, press the ‘Done’ button.


4.5 Tips for Optimal Scanning Results


  • Space Requirement: Ensure the patient is positioned in an open area with at least a 1-meter clear radius around them. This space is necessary for unobstructed movement during the scanning process.

Lighting Conditions

  • Uniform Lighting: Choose a room with good, even lighting. It’s crucial to avoid direct sunlight or shadows, as they can affect the accuracy of the scan. Uniform lighting helps in capturing the intricacies of the scanned area more precisely.

Scanner Handling

  • Using Scanner Handles: For better stabilization and control, hold the scanner using its designated handles. This allows for smoother movement and more accurate data capture.

Patient Positioning

  • Optimal Placement: Position the patient so that the area to be scanned is easily accessible. Ensure you can physically move around the target area without any disturbances or obstructions.

Troubleshooting and Common Issues

  • Losing Tracking: If tracking is lost during scanning, aim the camera so that the entire object is in the middle of the screen. This reorientation often helps in regaining tracking. For more detailed information, refer to section 4.4.

  • Scanner Connectivity: If the app does not recognize the scanner, verify that the scanner is properly connected to the iPad via a USB Type-C cable.

  • Reflections and Translucent Objects: Avoid scanning surfaces that are highly reflective or translucent, as these can cause inaccuracies in the 3D model.

  • Movement: Ensure that the patient remains as still as possible during the scanning process. Movement can cause blurring and inaccuracies.

Best Practices

  • Consistent Scanning Distance: Maintain a consistent distance between the scanner and the object. The ideal range is usually between 0.5 to 2 meters.

  • Gradual Movement: Move the scanner slowly and steadily around the object. Rapid or jerky movements can disrupt the scanning process.

  • Complete Coverage: Make sure to cover every angle of the scanned area to ensure a complete and accurate 3D model.

  • Regular Calibration: Regularly calibrate your scanner as per the manufacturer’s guidelines to ensure optimal performance.

4.6 Reviewing the Scan

  • Manipulating the Scan: On the next screen, you can manipulate the scan by moving, rotating (with one finger), and zooming in or out (with two fingers).

  • View Options: Toggle between X-ray, standard, and color views for a better assessment.

  • Approving or Rescanning: Choose to approve the scan or redo it by selecting the appropriate option.
