title: Biological tissue simulation and standard testing material for MRI.
abstract: The polyacrylamide gel is proposed here as a phantom material for NMR imaging. This substance has electrical and NMR relaxation characteristics very similar to those of biological tissues. The thermal and time stabilities also make this material a convenient standard for MRI.
