A photo of a patient, of a body segment or in the position required for the analysis may be measured by professionals. Measurements can be taken after specific calibration; there are many types of measurements (linear, angular, angular between two segments, etc.). Virtual plumb-lines can also be drawn on the photo for further reference during postural analysis and to detect forms of dysmetria. Another function professionals may find interesting is the chance to produce a virtual representation of the entire skeleton – and of the vertebral column in particular – if adhesive markers are first attached to the suitable “anatomical landmarks” on the patient.
