The therapist will request for you to get prepared for the scan by removing jewelery, etc., and will be offered a front torso drape for women in the case of a spinal measurement.
Depending on the type of scan, the therapist may need to place small light-reflecting markers onto necessary measuring points on the body. These are later easily removable by the patient after the scan is complete. Once prepared for scanning, the therapist will request you to step onto the scanning/measurement treadmill, and may adjust your foot positions for proper alignment for the scan. Depending on the type of scan being performed, it is possible that the scan will take place while simply standing on the treadmill, or while walking. The therapist will give guidance and feedback the entire duration of the scan.
As the scan is using a light-optical scanning method, the room will be slightly darkened to ensure the best scanning environment, and you as the patient will not feel anything at all. The scan is done entirely with light-technology, and does not take more than a few minutes to perform the actual scan and analysis, at which time it is complete.
