Image formation and other principles

Understanding ultrasound image formation is essential for accurate recognition of the normal anatomy and detection of pathologies. What constitutes an ultrasound pulse? How does it interact with tissues to form echos and ultimately a recognizable image? What is spatial resolution and how does it affect lesion perceptibility? This short video clip highlights the principles concepts […]
