Some phantom designs for radiation dosimetry and CT applications.
Solid phantoms designed with nesting, rotatable cylinders, allow increased flexibility in the positioning of dosimeters or test objects, permitting continuous movement as in a water phantom, but with increased ease of handling. Using such phantoms, measurements can be made at almost any point in the cross section of a phantom, an ability not achievable with currently existing solid or water phantoms. A separate phantom design allows easy measurement at points along circles or radii in a phantom.
