Abstract: A perfusion chamber for use in a phantom including a waterproof housing containing a porous material, the porous material defining fluid paths between pores and tubular channels within the porous material; and a reservoir for use in a phantom, a pump mechanism for use within the bore of an MRI scanner, a phantom for use in an MRI scanner, and a method for calibrating a scanning device.

Abstract: A phantom for use in an MRI scanner includes an outer housing and a plurality of vessels located within the outer housing, where each of the vessels contains a material. The value of a property of the material at a particular temperature is different for each of the vessels. The phantom also includes a phase change material between the outer housing and the vessels. Also provided are a method for manufacturing a phantom, a method for obtaining calibrated measurements from non-calibrated images using a phantom, a system for obtaining calibrated measurements from non-calibrated images, and a coil assembly for use in an MRI scanner.
