Commercial ultrasound scanners have a dedicated control on the user interface that allows the sonographer to specify the angle correction. Nevertheless, it is widely recognized that incorrect angle correction is a leading cause of error in blood velocity measurements performed using Doppler ultrasound. In fact, it is noted in the top three amongst Top Ten Doppler Errors and Artifacts [Pegasus lectures]. Dejong13 from the Inter-societal Commission for the Accreditation of the Vascular Laboratories (ICAVL) commission reported that as high as 35% of the applications for accreditation received by the ICAVL demonstrate improper angle correction techniques, making angle correction issues one of the most common causes for delayed decisions.
