CEPH
Calibrating Digital Cephalo Data for Software Analysis
Digital cephalo data must be calibrated for whatever analysis software you are using.
Measurements will not be correct if the data is not calibrated.
* Cephalo image data has a resolution of 176 dpi.
* Refer to the user’s manual for your analysis software for instruction on how to calibrate the data.
Calibration Data
* A CD disk with the calibration data is provided. It is titled “Chart(176dpi).jpg”
How to Use the Calibration Data
♦ Import the data into your analysis software.
♦ Refer to the user’s guide for your analysis software to perform the calibration.
* The distance from the center of one cross to the next in the data image is 27.5 mm.
Therefore, the total distance of 4 crosses is 110 mm.
♦ Based on the above distances, select calibration points and check the distance between them.
For example, calibrate the software so that the distance from one cross to the fourth cross away from it is 110
mm.
* Keep the calibration data in a handy, safe place.
We recommend that you copy the data onto your hard drive in a folder named “C:\Program Files\3dxcom”
