About a new method for the 3D determination of the human spine geometry

摘要

The majority of the population suffers of mild or severe spinal column deformations, such as scoliosis, lordosis, cifosis, leading to the reduction of the personal comfort and the reduction of the physical and intellectual effort capacity, also leading to severe distortions of thorax shape and alteration of the respiratory process. In order to emit the right diagnosis it is necessary to measure 3D geometry parameters of the human spine including the rotations angle between the vertebrae. The classical non-invasive investigations methods don't establish vertebrae rotation angle. This paper presents a method for the determination of the vertebrae rotation angle with a noninvasive investigations method using the ultrasound device. It is assumed that every vertebra is associated with a precision point and a characteristic line.
