Three-dimensional metric, perfusion and metabolic compartment spectroscopy phantom

摘要

A method and apparatus for calibrating NMR imaging and imaging spectroscopy devices. A precise three-dimensional cartesian grid allowing measurable three-­dimensional fluid flow is established. T₁/T₂ and regional spectroscopy is precisely measured at diverse placed in the grid. Gradual system change over time is measured by pumping fluids through the grid. A modular embodiment can be reassembled into different shapes by the user, and provides both flow-through and static fluid measurements.
