title: Empirical beam hardening correction in the measurement of vertebral bone mineral content by computed tomography.
abstract: Computed tomography (CT) was performed on phantoms to evaluate beam hardening effect in the CT measurement of bone mineral content of the vertebrae. It was found that the CT number of bone-simulating solutions was in linear relationship with the logarithm of exp(-zeta 2l) X 10(7). This exponential is a good estimate of the beam hardening effect in a vertebral study.
