Video Library

This is a collection of real-time, contact B-scan images demonstrating cross sections of many anatomic entities, presented as a teaching tool for primary pattern recognition.
 
These movies are contributed by ultrasonographers from many sites. An editorial panel reviews all movies for clarity and representation.
 
A small graphic demonstrates probe placement, ultrasound scan area and probe movement or ocular motion.  Ultrasonic image view is noted. Coronal or sagital images are listed and depicted. Gain levels are presented within the movie screen area. Each movie segment is reviewed for diagnostic concept categories: Real-time, Gray scale and 3-D thinking.
