Selectively adjustable phantom that is compatible with a magnetic resonance imaging system and environment

A selectively adjustable phantom system configured for use in a medical imaging system that is compatible with a magnetic resonance imaging environment, the selectively adjustable phantom system comprising:

• A phantom housing having formed therein an array of compartments divided into sub-arrays that are distinguished from each other by a ratio of the amount of fluid resent within the compartments;
• a plurality of fluid circuits, each fluid circuit connected to at least one of said compartments in a sub-array;
• a plurality of detachable fluid reservoirs external to the phantom housing and selectively coupled through the plurality of fluid circuits into portions of the sub-arrays within the phantom housing;
• and
• a control system configured to allow user selection of the selectively coupled portions of the subarrays connecting with the plurality of detachable fluid reservoirs in order to allow the sub-arrays to be selectively filled to a desired level through the fluid circuits by the fluid reservoirs.
