Abstract: A phantom assembly for testing x-ray equipment comprising a phantom assembly for testing x-ray equipment comprising at least one image plate made of at least one image plate material, at least one base member made of at least one base material, at least one step surface formed in the base member, and at least one mesh insert. The at least one base material is selected, sized, and dimensioned such that base member yields a transmitted reference signal in addition to at least one transmitted energy test spectrum associated with the at least one step surface. The at least one mesh insert is selected, sized, and dimensioned such that the at least one mesh insert yields a transmitted energy resolution signal.

Abstract: 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.
