The comet tail artifact
M. C. Ziskin, D. I. Thickman, N. J. Goldenberg, M. S. Lapayowker and J. M. Becker
A description and explanation of an unexpected echographic appearance in a patient who had sustained an abdominal shotgun wound is presented. In the B-scans, a trail of dense continuous echoes, simulating a comet tail, is seen distal to each lead pellet. This comet tail appearance is shown to be a type of reverberation artifact. The effect of object size, shape, composition, and orientation on the appearance of this artifact is demonstrated. This article has been cited by other articles:
