Dual-Cavity MRI Breast Phantom
An MRI phantom is a verification device, typically representing a human body part. It’s used to evaluate, analyze, and tune the performance of an MRI scanner and RF coils.
A small but complicated rotationally-molded MRI phantom. It is a hermetically sealed, fluid-filled low-density polyethylene vessel. The phantom has two cavities; one filled with a saline solution, the other with mineral oil. At the centre is a plastic plate machined with a pattern of high precision cut-outs.
Like all MRI phantoms and coils, it has to be completely free of metal fragments.
