Abstract
A filter changing assembly that can be used in, for example, a radiology system includes shape filters that can used to shape a radiation beam and that can be moved back-and-forth, for example. The filter changing assembly also includes beam hardening filters that can be used to change the energy spectrum of the radiation beam, and that also can be moved back-and-forth, for example. The filter changing assembly includes a control system that can be used to select at least one of the filters and automatically move the selected filter from one position to another position.
