Abstract:
The investigation has shown that the effect of beam hardening and the nature of surrounding structures must not be neglected when carrying out quantitative measurements. This is particularly true in the presence of strongly attenuating, and therefore strongly beam hardening structures such as bone, in regions where there are wide variations in CT values and when using varying kilo-voltages. Within the range of 0 to 200 HU, the effect of beam hardening is less important when compared with other statistical errors.
