A phantom assembly for testing x-ray equipment comprising at least one image plate made, at least one base plate, at least one first plate, at least one second plate, at least one third plate. A base material is selected such that a base plate, and a image plate yield a first transmitted energy spectrum that emulates a first reference energy spectrum. A first plate material is selected such that a first plate, an image plate, and a base plate yield a second transmitted energy spectrum that emulates a second reference energy spectrum. A second plate material is selected such that a second plate, an image plate, and a base plate, yield a first transmitted doserate that emulates a first reference doserate. A third plate material is selected such that a third plate, a base plate, and a first plate yield a second transmitted doserate that emulates a second reference doserate. |
