Ultrasound Artifacts 3: Miscellaneous Sources of Artifact

Ultrasound artifacts, which are becoming increasingly rare as technology improves, can still lead to critical errors in interpretation if they are not recognized and dealt with appropriately. A proper understanding of how they are created allows the echocardiographer to recognize, and work around these potentially hazardous pitfalls. This course focuses on miscellaneous sources of ultrasound artifact, including range ambiguity, mirroring, and ghosting. (NOTE: This material is best understood after completing The Physics of Ultrasound series first.)

You will learn:

  • Non-parallel beam alignment
  • Range ambiguity
  • Mirroring
  • Transit time effect
  • Ghosting and beam width artifacts
