The following illustrates a standard operating procedure (SOP) for aligning a 3D foot scan in RapidShell3D.

Prerequisites

  • Prescription loaded into RapidShell3D

Refer to the following guide for more information SOP: Loading Prescription in RapidShell3D

Goals

  • Align a 3D foot scan in RapidShell3D

Procedure

  1. Click Files → Display Left Foot

  2. A 3D scan of the patient’s left foot should now appear on the screen

  3. Click Place Points

  4. In specific order, click the Heel Point → 1st MPJ Centre Point → 5th MPJ Centre Point

  5. Click Align for Valgus or Align for Varus

  6. Click Accept

  7. Click Apply

  8. Position the scan in the Plantar view using the controls along the bottom toolbar

  9. Referencing the Scan Angle, Forefoot Varus or Forefoot Valgus measurement on the prescription, position the scan in the Heel view using controls along the bottom toolbar.

    (info) You must ensure that the prescription form includes an Acceptable Reference Measurement. You may refer to the following guides for more information.

    SOP: Heel Bisection Measurement
    SOP: Forefoot Varus/Valgus Measurement

    Acceptable Reference Method 1: Heel Bisection Alignment Method

    You may use the blue Z-axis line to reference the heel bisection in neutral (0°). You can then use the Invert and Evert controls from the bottom toolbar to rotate the scan into the alignment specified in the Scan Angle field on the prescription. The scan must be in a per-vertex 3D colour format.


    Acceptable Reference Method 2: Forefoot Varus/Valgus Alignment Method

  10. Position the scan in the Medial view so that the blue Z-axis line is breaking through the heel of the scan at approximately 20mm in height


When generating a prescription from LaserCAM Prescribe, the Name of Clinic field is used to create a directory within the C:\3DScanner\Data folder. For example if Clinic Name was entered as Name of Clinic, you would need to navigate to theC:\3DScanner\Data\CLINICNAME folder.

The First Name and Last Name patient details fields are used to generate a patient specific data sub-directory within this clinic folder. A unique code for the job is also included within the folder name to help differentiate multiple folders for patients with the identical first and last names.

For example, if your patient was named John Smith, the patient folder would resemble the following.

C:\3DScanner\Data\CLINICNAME\CLINICNAMECDFF700020_John_Smith

4. The prescription will now be loaded within RapidShell3D.

If the prescription CSV name is loaded within the top bar of the RapidShell3D (image above) the prescription has been successfully loaded.
