Adult Ear for X-Ray CT, US, MRI
The Adult Ear Phantom is designed around the complex anatomy of a human ear and is valuable for researching and developing noise reduction equipment. It can be customized for projects involving Ultrasound, X-Ray/CT, and MRI imaging. The phantom is an ideal tool for testing and calibrating hearing aid equipment and can be used as a stand-alone product or incorporated into the complete skull or head phantoms.
