Calculation of Mass Attenuation Coefficients for Pedicle Screw by Monte Carlo Simulation

Spine fixation is required in cases such as congenital spinal curvatures, vertebral fractures, sagittal collapse over time, painful kyphosis, and bone load due to tumors. Although there are many methods the literature, most commonly used spine method with pedicle screws. In these cases, it known that screws frequently body. this study, how radiological exposure of column dose was evaluated by simulation methods. First, elemental analysis screw analyzed via Scanning Electron Microscopy (SEM) equipped Energy Dispersive X-ray Spectroscopy (EDS). Then, compositions obtained were for codes. subsequently, half-value thickness attenuation coefficient calculations conducted column. Both XCOM software MCNP (Monte Carlo N-Particle) code obtain photon interaction parameters within energy range 60-250 keV.
