摘要: This paper deals with the recovery of porosity bone from measurements its effective electrical properties. The microstructural information is contained in spectral measure Stieltjes representation complex permittivity or conductivity and can be recovered over a range frequencies. problem reconstruction very ill-posed requires use regularization techniques. We apply method to properties cancellous numerically calculated using micro-CT images human vertebrae. presented based on an analytical approach does not rely correlation analysis nor any priori model micro-architecture. However knowledge constituents (trabecular tissue marrow). These vary patient patient. To address this issue, sensitivity technique was performed. Normally distributed random noise added data simulate uncertainty possible experimental errors values are good agreement true even assuming high level estimation components. results prove future potential impedance spectroscopy for vivo monitoring treatment osteoporosis.
