MR Compatible Heart Phantom for Medical Research
Timinger H, Borgert J, Krueger S
We present a pneumatically driven dynamic heart phantom for development and evaluation in medical research. The phantom contains an elastic ventricle phantom including vasculature which is reproducibly deformed by simulated heartbeat and respiration. Motion patterns and vasculature can be customized depending on the application to be simulated. The phantom can be imaged using MRT, CT, or X-ray. The phantoms control unit provides simulated ECG and respiratory signals. Possible applications include imaging tests, interventional and flow experiments. During evaluation, no B0 inhomogeneity was detected and gated 3D MR images of the moving phantom showed no motion artefacts at all.
