Abstract
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.
摘要
作者对一种由聚氨酯和聚异氰脲酸酯组成的商用泡沫材料进行了表征，该泡沫材料在飞机、汽车及相关行业中作为模型部件销售。作者发现，这种泡沫材料在低于-400亨氏单位的范围内可能适合用作密度参考标准。该范围与肺组织的密度一致。这种泡沫材料可能有助于使肺部疾病的诊断更加系统化。
