Ultrasound Imaging Techniques and Artifacts

An introduction to the physics and technological principles of diagnostic ultrasound is presented, including (1) a discussion of ultrasound-tissue interactions; (2) the pulse-echo technique; (3) transducers and ultrasound machine instrumentation for the detection and signal processing of echoes and image formation; (4) Doppler ultrasound; (5) B-mode and Doppler ultrasound artifacts. An overview of advanced ultrasound modes including harmonic and compound imaging, elastography, 3D imaging, ultrasound contrast, bioeffects, and safety of ultrasound is also provided.
