Design and Validation of a Multi-Modality Lung Phantom

Phantoms often mimic only one specific property of the body, and without relevant anatomical structure. We report the design and construction of an anatomic phantom that accurately mimics the in vivo properties of the lungs for both ultrasound and magnetic resonance imaging. The phantom demonstrated qualitative likeness to the lungs under ultrasound and quantitatively similar tissue relaxation characteristics using magnetic resonance imaging. Future work will determine if the phantom can be used to validate early-stage medical devices that operate within the lungs.
