The result could look like this.
  • Page 83 Service manual VistaVox S Background Tilting of the collimators cannot be corrected by the unit or by the software. Pressing Repeat X-ray image acquisition will therefore not improve the situation. A mechanical adjustment needs to be made. Adjustments can either be made on the collimator or to the sensor position. It is therefore necessary to check beforehand whether the collimator angle for Pano and CBCT is within the tolerance (which is presumably the case).
