Planar Saline Bath Phantom Of The Rush Head Model

The Rush head model is an approximation of the volume conducting properties of the human head. A planar saline bath phantom was developed to simulate the key properties of the Rush head model while creating a testing platform for implantable neural devices. The phantom closely mimics electrical properties of human tissue such as increased resistivity through the skull region and current flow that wraps around the head. Preliminary testing shows good agreement of the saline bath phantom to predictions from a computer model.
