Patent ID: 8708562

Claim:
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 plate made of at least one base material; at least one first plate made of at least one first plate material; at least one second plate made of at least one second plate material; at least one third plate made of at least one third plate material; wherein the at least one base material is selected, sized, and dimensioned such that one base plate, in combination with one image plate, yields a first transmitted energy spectrum that emulates a first reference energy spectrum; the at least one first plate material is selected, sized, and dimensioned such that one first plate, in combination with one image plate and one base plate, yields a second transmitted energy spectrum that emulates a second reference energy spectrum; the at least one second plate material is selected, sized, and dimensioned such that one second plate, in combination with one image plate and one base plate, yields a first transmitted doserate that emulates a first reference doserate; and the at least one third plate material is selected, sized, and dimensioned such that one third plate, in combination with one image plate, one base plate, and one first plate yields a second transmitted doserate that emulates a second reference doserate.
