By Zachary H. Levine, Mingdong Li, Anthony P. Reeves, David F. Yankelevitz, Joseph J. Chen, Eliot L. Siegel, Adele Peskin and Diana N. Zeiger


The authors characterized a commercially available foam composed of polyurethane and polyisocyanurate which is marketed for modeling parts in the aircraft, automotive, and related industries. The authors found that the foam may be suitable for use as a density reference standard in the range below −400 Hounsfield units. This range is coincident with the density of lung tissue. The foam may be helpful in making the diagnosis of lung disease more systematic
