Abstract
Numerous types of artifacts can result in clinical misinterpretations in computed tomography. Phantom materials and techniques of construction which would produce objects similar enough to the human body to test the accuracy of CT in vivo were evaluated. The object used for this purpose is a thoracic section with 5 soft-tissue materials, representing adipose tissue, muscle, heart, esophagus and lung, and 3 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 5 commercial scanners were identified.This publication has 1 reference indexed in Scilit:
