Abstract
A multimodality phantom apparatus includes a housing and a system of materials disposed within the housing. The system of material includes a first amount of abase material, a second amount of glass microspheres, a third amount of CaCO3, a fourth amount of gadolinium contrast and a fifth amount of agarose. The housing may include a plurality of compartments and at least one slot. The system of materials may be disposed within at least one compartment. The slot may be used to receive a dosimeter.

A multimodality phantom apparatus comprising:
- a housing;
- and
- a system of materials disposed within the housing and comprising:
- a first amount of a base material;
- a second amount of glass microspheres;
- a third amount of CaCO3;
- a fourth amount of gadolinium contrast and
- a fifth amount of agarose;
- wherein the second amount of glass microspheres, third amount of CaCO3, fourth amount of gadolinium contrast, and fifth amount of agarose are determined by optimization of a regression model over parameters T1, T2, and CT number.
