Phantom systems for radiation dosimetry with removable attachments
A phantom system is disclosed that includes a phantom and at least one removable phantom attachment configured to be attached to the phantom so that the phantom system may have an orientation, location and/or anthropomorphic feature identifiable to an imaging device.
1 . A phantom system comprising: a phantom; and
a removable phantom attachment configured to be attached to the phantom so that the phantom system has an identifiable orientation and/or location to an imaging device, the removable phantom attachment comprising an external and/or internal anthropomorphic feature with a shape configured for orienting and/or locating the phantom system.
2 . The phantom system of claim 1 , wherein the external and/or internal anthropomorphic feature is at least partially formed of a material having a density approximating water, tissue, bone, lung, or air.
3 . The phantom system of claim 1 , the removable phantom attachment configured to be attached outside of the phantom.
4 . The phantom system of claim 3 , wherein the external anthropomorphic feature is a nose, an ocular cavity, a mouth, a cranium, or an externally-visible portion of a clavicle, a pelvis, or a vertebra.
5 . The phantom system of claim 1 , wherein the removable phantom attachment is an anthropomorphic sheath configured to cover at least a portion of the phantom.
6 . The phantom system of claim 5 , further comprising an additional removable phantom attachment configured to be attached directly to the anthropomorphic sheath.
7 . The phantom system of claim 5 , wherein the sheath has a thickness of between 1.0 cm and 20 cm and includes an internal anthropomorphic feature.
8 . The phantom system of claim 1 , wherein the removable phantom attachment is a sheath configured to cover at least a portion of the phantom and configured for removable attachment of an external and/or internal anthropomorphic feature.
9 . The phantom system of claim 8 , wherein the sheath is configured to be a single piece that is shaped to wrap substantially around the phantom.
10 . The phantom system of claim 8 , wherein the sheath is configured to be a plurality of pieces shaped to wrap around the phantom, the plurality of pieces configured to connect at one or more connection points with one or more fasteners.
11 . The phantom system of claim 8 , wherein the sheath is configured to wrap partially around the phantom.
12 . The phantom system of claim 1 , wherein the external or internal anthropomorphic feature has a size, shape, or location corresponding to what the external or internal anthropomorphic feature would be on a person that has undergone an increase or decrease in weight.
13 . The phantom system of claim 1 , wherein the removable phantom attachment comprises an external or internal anthropomorphic feature having a size or shape corresponding to what the external or internal at anthropomorphic feature would be on a child.
14 . The phantom system of claim 1 , wherein a surface of the removable phantom attachment has a diffuse reflectivity of between 0.1 and 0.8 for light of wavelengths between 400 nm and 700 nm.
