The DIERS formetric is a light-optical scanning method based on Video-Raster-Stereography (VRS). Accordingly, the system consists of a light projector which projects a line grid on the back of the patient which is recorded by an imaging unit. 

A computer software analyzes the line curvature and generates from it – by means of the method of the Photogrammetrie – a three-dimensional model of the surface, comparable to a plaster cast. In opposition to x-ray, the DIERS formetric provides comprehensive information about the whole body statics and posture in only one measuring process, e.g. spine curvature (lateral and frontal), vertebral rotation, and pelvic position. 

Even muscular dysbalances can be detected based on the curvature image of the back surface. For the first time it is possible to visualize the complex motion pattern of the spine and pelvis during walking and to monitor the results. This technological breakthrough is based on the innovative software and an advanced camera system.

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.
