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 reflection and extraneous beams. (NOTE: This material is best understood after completing The Physics of Ultrasound series first.)

Please note this course includes a Reference section. For accurate completion status, you MUST review the reference section.
