Phantoms

MR compatible phantoms from tissue mimicking materials such as ethylene glycol or polyvinylpyrrolidone are used as a filler. Gel-phantoms combining a PVP solution with Agar can be constructed for MRI based safety validation of RF coils in MR thermometry. Fluid filled phantoms with ethyleneglycol or saline-solution can be used for system calibrations. Multiple phantom geometries, such as a pelvic mimicking or a head mimicking shape can be produced. Phantoms can be integrated with cavities for placement of thermal probes or an endo-coil.
