Using a procedure which resembles actual practice, it has been shown that an increase in kV. results in a reduction of radiation dose similar to that obtained by using the new high intensity rare earth screens while maintaining similar detail. In practical terms this means that there is only limited usefulness for the new rare earth screens. An exception to this is the screen which reduces dose while producing similar, or better, detail than a standard screen. We could demonstrate this for the film-screen combination Trimax alpha4XD.
