CPT (complex phase tracing) profilometry was selected as a method of choice for clinical use in back surface topography recording. Two mutually out-of-phase patterns are projected on the back surface of the patient, recorded and demodulated according to the CPT procedure. Ten subjects have been investigated, 3 subjects being healthy controls. The system was reliable in measuring back shape with millimetric definition (+/- 1 mm). It proved to be fast in acquiring topographical data, requiring less than 0.3 sec and, then, overcoming problems related to breathing of the patient. Data analysis was enough fast to provide a visual output within few minutes, allowing the examiner to perform a further acquisition, if needed, and the patient to appreciate the output of the analysis. Presence of asymmetry was easily detected and clearly highlighted; improvements related to treatment was evidenced in those subjects where a follow-up exam was performed.
