Applications of computer-aided rasterstereography in spinal deformity detection

摘要

In this paper, a methodology developed for analyzing surface shapes using computer-aide reasterstereography is discussed and its applications in the field of medical science are highlighted. In this methodology, deviations are extracted from projected horizontal and vertical rasters and used in generating a profile of the surface under consideration. The magnitude and direction of deviations indicate 3-D properties of the surface. This technique is suitable for screening children for spinal deformities because it is simple, fast and non-invasive. It does not require very specific setup due to the reduction of errors using symmetry of the human back. The positive cases detected by the system can be referred to the physician for further diagnosis and treatment.
