Abstract: Apparatus and method for simulating tracer interaction with living tissue. A chamber receives a fluid therein, and includes an inlet conduit for conducting the fluid into the chamber, an outlet conduit for conducting the fluid out of the chamber, a medium disposed within the chamber for modulating fluid flow, and a valve assembly for conducting the fluid into the inlet conduit. In some aspects, the fluid is a radiative tracer or a radiative washout fluid and the medium is configured to mimic a tissue, e.g., the heart, and portions thereof are capable of mimicking both normal and diseased tissues.

Abstract: A phantom according to the invention features a radiotransmissive vessel and a removable closure member, which together define a sealed chamber. A non-magnetic support member extends through a wall of the chamber—preferably through the closure member—and supports a hollow container within the sealed chamber. The support member is pivotally supported through the wall of the chamber by means of a non-leak pivot joint. The support member supports a magnetically drivable element—either a magnet or a ferromagnetic mass—on the opposite end that is not disposed within the chamber. By moving a co-acting magnetically driving element, movement of the support member, and hence the container within the chamber, can be controlled.
