Numerous types of artifacts can result in clinical misinterpretations in computed tomography. The authors have evaluated phantom materials and techniques of construction which would produce objects similar enough to the human body to test the accuracy of CT in vivo. The object used for this purpose is a thoracic section with five soft-tissue materials, representing adipose tissue, muscle, heart, esophagus, and lung, and three bone materials representing cortical bone, average rib, and "inner" (trabecular) bone. The accuracy of CT numbers for studies of different organs was assessed and sources of error in five commercial scanners were identified.
多种伪影可导致计算机断层扫描中的临床误诊。作者评估了体模材料和构建技术，这些材料和技术所产生的物体与人体足够相似，以测试CT在体内的准确性。用于此目的的物体是一个胸部切片，包含五种软组织材料，分别代表脂肪组织、肌肉、心脏、食管和肺，以及三种骨材料，分别代表皮质骨、平均肋骨和“内部”（小梁）骨。评估了不同器官研究中CT值的准确性，并确定了五台商用扫描仪中的误差来源。
