Abstract
Objective:To explore the effect of the BPPV precision manipulation treatment. Method:With 3D SLICER software we segment structure such as semicircular canal, eye ball, orbital and ear rod from MRI or CT volume data of patients which underwent MRI or CT scaning of inner ear, for measuring the spatial direction of semicircular canals and building semicircular canal modules with standard space coordinate system and embedding into 3D PDF files. Result:With the slice that divide the semicircular canal equally as the semicircular canal plane and the eyeball as reference object to determine whether it is symmetric, it is not only intuitive but also reliable for measuring the angle between the posterior semicircular canal. 3D PDF is intuitive, rotation angle can be adjusted according to the individual differences in the process of manipulation treatment, to observe and demonstrate the theoretical reduction effect before the actual operation. Conclusion:By reconstruction the three-dimensional semicircular canal structure from the inner ear image data of patients and measurement of the semicircular canal space direction, it is of a certain significance for BPPV precision manipulation treatment.
