An adjustable phantom ( 36 ) includes a base ( 202 ), an actuator ( 204 ) and a phantom ( 210 ). The phantom includes first ( 210 a ) and second portions ( 210 b ), each having a different value of a physical characteristic measured by a scanner ( 10 ). The phantom ( 210 ) is movable with respect to the base ( 202 ). In one embodiment, the phantom is well suited to simulating the arrival of contrast agent in a contrast enhanced imaging examination. |
