Normal Incidence - Video Lesson

Hey, everybody. Welcome to today's lesson on Doppler ultrasound. This lesson will explore how normal incidence affects Doppler imaging, the significance of the Doppler angle in velocity calculations, the role of angle correction in compensating for suboptimal angles, and strategies to optimize measurement accuracy in clinical settings. The angle of incidence is critically important in Doppler ultrasound. Therefore, understanding these concepts is necessary in your role as a sonographer. Let's begin. Remember, normal incidence occurs when an ultrasound beam is perpendicular to the structure being imaged, meaning the angle between the beam and the target is ninety degrees. In doppler imaging, this condition significantly impacts signal detection and velocity measurement. At normal incidents, no doppler shift occurs because there's no component of motion along the ultrasound beam's axis. Remember, at oblique angles or if the blood is moving directly toward or away from the transducer at zero
