Basic ultrasound beam formation and instrumentation.
This article is a brief review of ultrasound beam formation. Some detailed components of the ultrasound machine are discussed as a primer for the subsequent article on recent technological advances. The components of the ultrasound transducer responsible for broad bandwidth technology and electronic focusing are discussed in the context of optimizing resolution. Other aspects of ultrasound physics, including artifacts and interactions with matter, are not discussed.
