【 摘 要 】

Correct evaluation of the spine is important in detecting the deficiencies that may occur at this level, especially in case of scoliosis. It is proposed a new method of acquiring the coordinates of the column in order to generate a model of it. A number of eight coordinates has been chosen to use, a big enough number to assure a true model of the spine and a wide area of possible mathematical approaches. The acquiring system consists of eight accelerometers, from which is collected the pitch angle. This angle, as the angle of inclination in the frontal plan is used to compute the pairs (x, y), considering known the distance between the sensors. The accuracy of the model is validated by comparison with images taken during the measurement.
