Defining of the Shape of the Spine Using Moiré Method in Case of Patients with Scheuermann Disease

Nowadays spinal deformities are very frequent
problems among teenagers. Scheuermann disease is a one
dimensional deformity of the spine, but it has prevalence over 11% of
the children. A traditional technology, the moiré method was used by
us for screening and diagnosing this type of spinal deformity. A
LabVIEW program has been developed to evaluate the moiré pictures
of patients with Scheuermann disease. Two different solutions were
tested in this computer program, the extreme and the inflexion point
calculation methods. Effects using these methods were compared and
according to the results both solutions seemed to be appropriate.
Statistical results showed better efficiency in case of the extreme
search method where the average difference was only 6,09⁰.
